Ten years ago, KLa Systems was presented with the challenge of finding a more wear-resistant material for our jet aeration nozzles.  The inner nozzle the traditional jet aerator is the liquid propulsion nozzle of the jet aerator and continuously sees high volumes of motive liquid flow at velocities ranging from 33-46 ft/s.  Traditionally, these inner jet nozzles were made from the same FRP material as the outer jet with the industry accepted corrosion/abrasion liner made up of C-Glass/Nexus and Silicon Carbide impregnated into the vinylester resin.  For many years this material had held up in most industrial and municipal bioprocesses with no adverse deterioration or wear of the jet nozzles.  It was when we entered the thermophilic biosolids treatment market when we determined we needed to upgrade to Kynar PVDF.  This material is both extremely chemical and wear resistance over a wide range of temperatures.

The Slot Injector™ System is a superior jet aeration system that is specifically applied to industrial biological treatment processes where fine screening is a standard pretreatment operation in both conventional and advanced air activated sludge applications.

The high-alpha factor and clean water oxygen transfer performance of KLa’s jet aeration technology results in low energy costs and reduced off-gas volume for industrial and biosolids applications.

Jet Mixers offer superior mixing of large diameter tanks by providing uniform energy distribution while minimizing power input. This mixing technology results in decreased reaction times, improved liquid blending and off bottom suspension of light, organic solids.  Jet mixers are used in wastewater treatment applications where blending, solids suspension, flow generation, or chemical reactions are key process parameters.  Jet mixers are fabricated of either FRP or stainless steel with no moving parts in the tank. Conventional pumps are used for the jet motive flow and are located just outside the tank for optimizing energy efficiency and ease in maintenance.

KLa Systems floating effluent decanters are used to draw clarified liquid from near the liquid surface of sequencing batch reactors and aerobic digesters.

A typical system consists of the Slot Injector™ aerators, jet mixers or jet aerators complete with in-basin piping system, back-flush system, liquid recirculation pumps, and air blowers.  The pumps supplied are either end suction centrifugal, submersible, or self-priming. Low pressure air is delivered by positive displacement blowers, screw compressors, multi-stage or high speed centrifugal blowers.

KLA SYSTEMS ARTICLES

  • In a small inlet off the coast of Northern Scotland, known as the Dornoch Firth, there’s been an effort to repopulate oysters that were extinct from overfishing. What’s special about this effort is that these oysters are being called upon to drink whiskey and help combat climate change.

  • As water resources are nearing a critical point, with population growth and environmental factors putting the squeeze on supplies, water scarcity has been an emerging concern across the globe.

  • As COVID-19 vaccination rates continue to inch upward across the U.S., office buildings and other businesses that remained closed are now springing back to life. However, because nobody has been around — to flush toilets, wash their hands, and drink from the water fountains — the water inside these facilities that remained stagnant long enough to harm those who return, if not properly addressed.

  • With temperatures rising and summer just around the corner, water meters are about to be speeding up. Not only can that get expensive, but water utilities in many parts of the country are struggling to keep up with demand.

  • Microplastics are a hot topic these days. Spawned by everything from plastic bags to laundered clothing, the volume of tiny particles that pollute our oceans has exploded in recent years.

  • Modern technology is a big reason that municipal utilities can provide clean and safe drinking water for customers, but even contemporary water professionals might be awestruck at the effectiveness of some ancient Mayan treatment systems.

  • Twenty years ago, some people viewed computational fluid dynamics (CFD) as more of a sales tool than an engineering tool. Since then, it has proven its validity and its value as a tool for analyzing wastewater aeration and process mixing performance. Here are some insights on the technology, its specific use in wastewater basins, and inside tips on how to apply it to greatest advantage across a variety of processes.

  • When it comes to wastewater aeration systems, experienced operators, consulting engineers, contractors, and executive decision-makers can appreciate the differences between a true workhorse and one designed by a committee. Here are six important considerations for keeping new or upgraded designs from casting a dark shadow on aeration cost, convenience, and consistency — even when multiple parties are involved in the process.

  • In 2001, when KLa designed its first aeration system, the two most prevalent biological wastewater treatment options were sequencing batch reactor (SBR) and conventional activated sludge (CAS) processes. Today’s options are much broader. Yet, cost-efficient aeration still remains an underlying challenge. This Q&A article provides a look at how the industry arrived at today’s opportunities and where it’s headed for the future.

  • Keeping pace with changing industrial wastewater treatment demands can raise multiple issues of oxygen demand, capital cost, and operating expense, often without the flexibility of taking basins out of service to upgrade to new levels of performance. Fortunately, there are alternatives for delivering more oxygen to treat more water, handling higher biochemical oxygen demand (BOD), or upgrading inefficient equipment — all without breaking the bank.

  • When you think about water efficiency, it might be difficult to fathom that humans have an advantage over their closest living animal relatives. However, a new study shows that people use as much as half the water that chimpanzees and other apes use daily.

  • Cybersecurity at municipal water utilities has been a growing concern in recent years, but the latest hack into a small Florida city’s water supply is shining a spotlight on the scope of the vulnerability and the challenges of preventing something similar from happening most everywhere else.

  • You might not be able to tell with a casual look, but rivers across the U.S. have been changing color. And that’s not necessarily a good thing.

  • Surviving a trip to Mars will be a tricky proposition. Based on the distance and resources needed for any journey, it will be necessary for astronauts to produce some of their own supplies, like fuel and water, after they arrive on the surface of our closest planetary neighbor.

  • Just off the coast of Georgetown, SC, a retired 65-foot fishing boat was recently sunk 50 feet underwater, where it joins a barge and nearly two dozen Army vehicles. Off the coast of Charleston, a short distance to the south, eight concrete towers of various heights have been installed on the sea floor.

  • Switzerland spends more than $200 million annually to combat littering, but this year its cleanup efforts feature a new type of rubbish: discarded face masks used for COVID-19 protection.

  • Few things will upset your vacation plans to the Gulf of Mexico quicker than news that a red tide is set to greet you at the shoreline. And that angst extends to restaurants, shops, and other businesses in the area, which take a beating when these harmful algal blooms, or HABs, drive away beachgoers.

  • Their name might sound like something out of a cartoon, but nurdles are causing quite the stir.

  • Droughts and water scarcity are making it increasingly difficult to farm for a growing global population. And while those supply factors could be disastrous if not addressed, newer technology applications are tackling the demand side of the equation.

  • Since the coronavirus started sweeping through the U.S., multiple research efforts have gotten underway to figure out how wastewater can provide clues about its spread. Now, some colleges and universities are planning to put wastewater under a microscope as an early warning system when students come back to campus this fall.

  • Every industry’s onsite wastewater treatment has its unique conditions and challenges. For distilleries, high levels of biochemical oxygen demand (BOD), nitrogen, total dissolved solids (TDS), and total suspended solids (TSS) put extra pressure on optimal biological treatment requirements. Here are some techniques that can help distillers put a little extra money in the bank while meeting the challenges of environmental discharge requirements.

  • While wastewater effluent standards mandated by the U.S. EPA and individual states eventually come down to a number, it pays to understand how those standards are established and the challenges of meeting them in real-world applications. Here is a look at the multiple pieces of that puzzle, including their wastewater treatment implications for industrial-scale meat and poultry processing operations.

  • As local breweries grow in popularity, their initial focus on hand-crafted recipes can quickly shift to business realities such as the costs and logistics of process wastewater treatment. Publicly owned treatment works (POTWs), brewery owners, and consulting engineers all have roles to play in making that trajectory smoother for up-and-coming craft and microbrewers.

  • While dissolved oxygen (DO) levels are critical considerations in aerobic wastewater treatment processes, not every application maintains a consistent level of demand. How industrial wastewater treatment plants (WWTPs) track and fulfill those needs make a big difference in the optimum performance and cost-efficiency of their operations — including the equipment used to manage their processes.

  • As craft beer was embraced as an affordable luxury by many Americans in recent years, the number of breweries has exploded. However, that segment of the industry, as well as traditional brewers, are taking a massive hit during the current coronavirus pandemic.

  • Controlling stormwater to prevent flooding and pollution is a never-ending task in many places. And officials are finding just as many solutions in ancient engineering as they are in modern technology.

  • New Orleans may have survived Hurricane Katrina, but newer stresses are impeding the region’s ability to process stormwater runoff to prevent flooding and groundwater contamination. Storms, which are dumping more water into New Orleans than ever amid climate change, are the big contributor. However, humans aren’t making things any easier.

  • It may be decades or longer before technology allows the colonization of other planets, but space exploration for one of the most vital resources — water — is already in full swing.

  • Two decades ago, the public was captivated by Julia Roberts’ portrayal of Erin Brockovich, a film about a struggling single mother who goes after big energy for polluting groundwater with hexavalent chromium. When the dust settled, the result was a class-action lawsuit settlement for more than $300 million.

  • Oceans across the globe are losing oxygen at an unprecedented rate, which is putting marine life in a serious bind, according to a new report released by the International Union for Conservation of Nature.

  • Expect to see more solar arrays sitting atop waterways.

  • The environmental problems caused by single-use plastic water bottles continue to make headlines, but that hasn’t slowed down water-related business ventures.

  • After roaming the oceans for more than a half billion years, jellyfish may finally be poised to overtake Earth’s largest bodies of water.

  • The presence of dissolved solids presents both physical and financial challenges for aeration diffusers in any wastewater treatment operation and can be particularly problematic in high-concentration industrial and food-processing applications. Here are some warning signs, insights, and solutions for coping with conditions that can lead to excessive dissolved solids accumulation.

  • Managing the treatment of wastewater — especially industry-generated wastewater that can elevate dissolved oxygen (DO) demands far beyond those of municipal/residential applications — is hard enough. Trying to do so during upset conditions is enough to put any water treatment professional on edge. Here are several preventive and remedial options to keep in mind before or after DO readings go haywire.

  • On the afternoon of May 19, 2011 KLa Systems was contacted by one of their customers located in Virginia. The customer stated that their aeration basin was running at near 0 mg/l dissolved oxygen (DO) residual with their air supply blowers running at 100% of capacity. Based on the conversation it was determined that a KLa field service technician was needed on site immediately.

  • Too much of a good thing can create new problems as quickly as it resolves old ones. Maintaining a proper balance of antifoaming agents and polymer additives is critical for sustaining the appropriate air bubble size and distribution needed to achieve dissolved oxygen (DO) requirements for neutralizing high biochemical oxygen demand (BOD) in many industrial and food processing wastewater applications.

  • A balanced wastewater process is a beautiful thing — plenty of biochemical oxygen demand (BOD), plenty of O2, and all those hungry little microbes are fat and happy. But what can be done when dissolved oxygen (DO) takes a nosedive and there’s not enough O2 to satisfy industrial and food processing BOD? Here are some preparations to consider before wastewater treatment goes completely out of whack.

  • What do a drinking establishment and an eco-friendly writing utensil have in common? They both reflect new and unconventional ways that water is being injected into commerce.

  • Several advancements in solar technology may provide the answer to drinking water production in distressed regions of the world.

  • Too many dog owners think their pets’ waste easily breaks down in nature and is helpful to plants, so they leave it on the ground. The truth is that dog poo and other pet waste is loaded with germs such as e. coli and giardia that make people sick as well as nutrients that can fuel problematic algae blooms.

  • As with any industrial process, the right tool for the job depends on the nature of the task at hand. In aerobic wastewater treatment, that optimal choice often comes down to a balance between the biological and financial demands of the application. Either way, here are several performance comparisons of how multiple aeration methods and locations stack up in industrial wastewater treatment applications.

  • Aeration for industrial and municipal wastewater treatment involves more than simply moving volumes of air through a treatment basin. It really comes down to creating and sustaining an optimal oxygenated environment for microorganisms to convert oxygen consuming compounds into CO2 and water. Here are some key considerations for making better retrofit decisions about upgrading existing basin capacity and efficiency with jet aeration.

  • Unlike most municipal wastewater treatment plant (WWTP) applications, industrial wastewater can vary widely from one application to another, even within the same plant, depending on the process being run. Industrial wastewater professionals — especially those facing specific challenges or planned volume increases — can benefit from comparing key points of differentiation in jet aeration system options before making any upgrade.

  • Looking for a way to store massive amounts of excess green energy? Water may provide the answer.

  • The hardest aspects of comparing efficiencies among submerged aeration technologies are the many variables in capital expense (CAPEX), operating expense (OPEX), and complexity of wastewater makeup. Instead, consider comparing the physics of different aeration technologies and the relative costs associated with them. Here are five major categories for evaluating industrial wastewater aeration efficiency.

  • It took decades to solve the mystery of Garfield phones that were polluting French beaches. Turns out a load of the novelty item, modeled after the popular orange cartoon character, was slowly being purged from a shipping container that had been lost at sea. That begs the question: Are shipping containers like these polluting global waterways at alarming rates?

  • Long thought to be an issue that plagued the United Kingdom most acutely, the scourge of fatbergs has been making itself known stateside.

  • An unusual culprit has been identified as the source behind rotten smelling water in Austin, Texas. Though the source of the smell was surprising, at least it wasn’t too difficult to deal with.

  • The fallout from Flint, Michigan’s lead-contaminated drinking water has been far-flung and long-lasting.

  • Wastewater service charges vary considerably across EPA regions and States. That’s one of the key findings from the National Association of Clean Water Agencies’ (NACWA) Cost of Clean Water Index. If you live in Montana, Wyoming or the Dakotas (EPA Region 8), your average service charge of $261 a year is considerably less than the $884 your fellow Americans up in New England (EPA Region 1) are paying.  As you can imagine, much of the difference is to do with population size and geography.

  • Did you know that the Environmental Protection Agency (EPA) had a published Contingency Plan in anticipation of the current government shutdown? I guess in hindsight, you would have expected it for an agency with 134 facilities dotted across the country. And in fact, it’s required by the Office of Management and Budget (OMB) under Circular A-11, Section 124 that all government agencies have plans for an orderly shutdown “in the event of an absence of appropriations.”

  • The federal government recently released its fourth National Climate Assessment which focuses on the impact climate change will have on the U.S. economy over the next century. As mandated by the Global Change Research Act of 1990, the U.S. Global Change Research Program takes a comprehensive look at climate change and its effects on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems and biological diversity.

  • According to the U.S. Geological Survey, groundwater supplies half of all drinking water to the U.S. population, nearly all of it to our rural population and over 50 billion gallons per day for agricultural needs. But according to new research out of UC Santa Barbara, supplies may be more limited than previously thought.

  • Last month, The Ocean Cleanup launched its first plastics cleanup system (System 001) in an area of the Pacific between Hawaii and California named the Great Pacific Garbage Patch. It constitutes the world’s largest accumulation zone, known as a gyre, of ocean plastics. Boyan Slat, CEO of The Ocean Cleanup, estimates that half of the Great Pacific Garbage Patch will be removed from the Ocean within five years as additional systems are applied until it achieves full-scale deployment.

  • Five years ago, the city of Detroit, MI, filed the largest municipal bankruptcy in U.S. history at an estimated $18 to 20B. At the time, there was a lot of speculation in the water market as to how the city would continue to serve its citizens with viable water and sanitary sewer services. Ultimately Detroit reached a deal with neighboring Oakland, Wayne, and Macomb counties to create the Great Lakes Water Authority (GLWA), a new regional water and sewer authority. Spring forward to today and despite Detroit’s population continuing to dwindle, it’s water and sewer provision under the GLWA has recovered significantly.

  • When you think about areas of the world where people have limited access to clean water, I’m guessing hot, sunny, arid climates come to mind. In an interesting twist, a couple of innovations are using those exact conditions to create potable water.

  • The latest disposable causing a stir in the wastewater treatment world is the contact lens. Researchers from Arizona State University recently presented their findings at an American Chemical Society event showing that contact lenses flushed down the toilet or washed down the drain can pass through wastewater treatment plants and accumulate in sewage sludge. As sludge is often applied on land for disposal and fertilizing, macro- and microplastics from lenses enter terrestrial ecosystems.

  • Recently, Ohio Governor John Kasich issued an executive order allowing the Ohio Department of Agriculture to set requirements for storing, handling and applying manure as well as nutrient management plans in an effort to reduce nutrient pollution and algal bloom growth in Lake Erie. The order is set to affect 7,000 farms across 2 million acres.

  • The annual Lake Erie harmful algal bloom forecast was recently released by the National Oceanic and Atmospheric Administration (NOAA), predicting that western Lake Erie will experience a harmful algal bloom (HAB) of cyanobacteria this summer. The bloom is expected to be smaller than in 2017 but larger than the bloom in 2016.

  • Sniffer dogs have been used for a while in the oil and gas industry to find leaks. But recently, dogs have begun to be used to find leaks in water mains.

  • For most of the United States, we’ve reached the time of year where Americans desire to maintain a perfectly green lawn starts to be tested by the warmer and dryer summer months. From the water industry’s perspective, it’s staggering just how many billions of gallons of treated water ends up being sprayed across our hallowed front and back yards in maintaining a full and aesthetically-pleasing lawn.

  • Jet aeration systems are extremely efficient due to their high alpha factor and clean water oxygen transfer performance. Proper start-up, operation, and maintenance will ensure reliable service and a long life.

  • Conserving energy and saving costs are always on the minds of wastewater professionals. Aeration accounts for more than 50 percent of electrical usage at most treatment plants. Improved aeration efficiency will always work toward the goals of saving energy and reducing operating costs.

  • As industries expand, they typically need to increase the capacity of their wastewater treatment facilities. Increasingly stringent regulatory requirements, such as lower nitrogen limits, may also signal the need to boost treatment capacity. Installing additional tanks and larger equipment not only adds capital costs but increases operating costs as well.

  • A couple of weeks ago, Environmental Protection Agency (EPA) administrator Scott Pruitt called PFAS groundwater contamination “a national priority” and pledged action at an EPA national PFAS leadership summit.

  • Writing for Mental Floss in 2015, Emily Becker finished her article on the twenty-year export of New York City’s wastewater sludge to Colorado with the words “there are no plans for the New York City poop train to leave the station again.” Fast forward to 2018 and the wheels are once again rolling.

  • It is almost too heart-breaking to watch. In the YouTube video, marine biologists from Texas A&M University extract a plastic straw from a sea turtles’ nose as the creature winces in pain. Today that video has been viewed more than 22 million times, drawing attention to the hazard that plastic straws present to animals and our environment.

  • Saturday, March 24th was a busy day at the Brightwater Clean-Water Treatment Facility in Woodinville, WA, just outside Seattle. The Utility’s Education and Community Center was full of family-oriented science experiments and art projects with organized tours of the wastewater treatment plant taking place throughout the day. All in recognition of International World Water Day which had occurred two days before.

  • For many people, hot springs conjure up thoughts of cleansing and purity. For centuries, humans have visited hot springs to relax and recover. But as with any natural water body, hot springs can also exhibit biota that can infect and in severe cases kill.

  • Aeration is the heart of every activated sludge system, as well as the most energy-intensive process. When designing or modifying a wastewater treatment facility, the aeration system design will have lasting impacts on effectiveness, capital and operating costs.

  • Last year, the National Oceanic and Atmospheric Administration (NOAA) recorded the largest hypoxic zone in the Gulf of Mexico since monitoring began 32 years ago. Hypoxic waters, often referred to as dead zones, have dissolved oxygen concentrations of less than 2-3 ppm. They are caused by eutrophication or excess nutrients that promote algal growth in water bodies. As algae decompose, they consume oxygen creating dead zones.

  • You may have read recently that Orange County Water District (OCWD) and Orange County Sanitation District (OCSD) set a Guinness World Record for the most wastewater recycled to drinking water in 24 hours. The record attempt kicked off on February 15th 2018 to mark the 10th anniversary since the districts’ Groundwater Replenishment System was launched and culminated with more than 100 million gallons per day (MGD) being produced.

  • Sequencing Batch Reactors (SBRs) are a variation of the activated sludge process that combine treatment steps into a single basin. Based on a fill-and-draw method, major phases of the SBR process include a cycle of fill (with or without aeration), react, settle, decant, and idle. Today, successful flow control strategies have made SBRs state-of-the-art technology. SBRs are commonly used today and are especially beneficial for many industrial applications.

  • Over the past 10 years, DC Water has become the harbinger of the modern water utility. It’s often unconventional approach to tackling age-old problems usually elicits one of two responses from other utility professionals. The first response is one of resignation — if only I had the budget that size permits, I’d be able to do similar things. And the second is one of awe — there’s no way I have the amount of gumption to convince regulators or customers that I have a better way.

  • One of the great turnaround stories in the history of our nation’s water bodies is that of the Chesapeake Bay. Since 1976 when the Environmental Protection Agency (U.S. EPA) first undertook a comprehensive study of the Bay, efforts to address excessive nitrogen and phosphorous degradation of water quality have steadily improved the Bay’s complex ecosystem.

  • When California’s AB2022 went into effect earlier this year, allowing the bottling of advanced purified reused water for educational purposes, Orange County Water District (OCWD) and Orange County Sanitation District began the #GetOverIt! campaign to continue to push for consumer acceptance of recycled water systems.

  • Unless you spent the last election cycle hiding under a rock (and no blame if you did), you are no doubt aware of the growing rift between the two major political parties of the United States. As reported in The Atlantic citing polling from the Pew Research Center for the People and the Press, those who identify as Democrats are becoming more liberal and those identifying as Republicans swing ever more conservative.

  • Weather plays an important role in how Americans think about water. And I don’t mean when it’s raining, we decide to grab a raincoat.

  • It wasn’t so long ago that city rivers were some of the more polluted bodies of water on the planet. In 1969 for example, the Cuyahoga River famously caught fire after years of unabated pollution, spurring an environmental movement to clean up the nation’s waterways.

  • A few years back, the Secretary of the International Farm Management Association (IFMA) announced that if the world’s population consumed food in the same manner as the citizens of the U.S., we would need 6 planet earths to keep up with demand. Now we know that the traditional diet of hamburgers, steaks and all-you-can-eat buffets across America’s heartland is slowly being diversified by a growing number of eating options, many far greener, i.e. Salad Works. 

  • Membrane bioreactor (MBR) plants are found all around the world, serving as a go-to method for treating wastewater through a combination of processes. But as this technology gains popularity, operations must contend with the inherent aeration problems it presents.

  • New York City treats 1.3 billion gallons of wastewater a day across its 14 wastewater treatment plants. The city has seen a precipitous drop in fecal coliforms, with the NYC Department of Environmental Protection (DEP) reporting that fecal coliforms per 100 mL of water has fallen from 1,000 in 1972 when the Clean Water Act was passed to closer to 10 as of 2009.

  • On January 1st 2017, Philadelphia’s controversial “soda tax” went into effect, adding a 1.5-cents-per-ounce on sugary beverages sold in the city. Several cities across the U.S. have enacted similar taxes in a bid to battle diet-related diseases such as obesity and fund more healthy activities within their communities.

  • Cities all over the country have been prioritizing clean water through a variety of different programs and the City of Brotherly Love is among the ranks.

  • The Great Barrier Reef — a chain of 2,900 individual, underwater corals comprising the world’s biggest structure made by living organisms — is one of the most visible victims of climate change.

  • The Merrimack River is considered one of the major beneficiaries of the Clean Water Act of 1972.

  • With sandal-and-swimsuit season right around the corner, policymakers are raising awareness about the problem of beach pollution.

  • In a nation of red states and blue states, water policy is an issue that often dissolves party lines.

  • Boston Harbor used to be an icon of water pollution in the U.S. But a massive cleanup effort — one of the biggest restoration feats in the nation’s history — has revived the harbor in the last three decades.

  • Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort.

  • As more wastewater treatment facilities focus on ways to cut costs and improve environmental stewardship through energy reuse and sustainable practices, the industry is becoming a leader in the world of tomorrow.

  • Although they may appear crude on the surface, biosolids represent the future of wastewater treatment. This organic substance contains energy and nutrients, and thus the potential for resource recovery and increased energy efficiency by wastewater treatment operations.

  • Those who are philanthropically-minded need look no further for a cause than that of water. After all, this is a fundamental aspect of human existence and one that is shockingly scarce in some parts of the world.

  • It may seem farfetched, but the reality is that many Americans don’t have regular access to clean drinking water.

  • Wastewater treatment plants process tons and tons of sludge every year and they have to contend with the question of what to do with it. Increasingly, biosolids are looked at as an opportunity to help the planet.

  • On the surface, wastewater treatment operations don’t appear to be handling precious material. But these facilities are actually processing a great deal of value every day.

  • On his way out of office, Barack Obama made a final effort to bolster the Waters of the United States rule (WOTUS), which has drawn controversy since it was issued in 2015.

  • In a drastic about-face, California has gone from historically desperate drought conditions to an inundation of water that has brought its own set of problems.

  • In wastewater treatment, aeration systems are more than just critical. They can be seen as the central nerve of the whole operation, the part of the process that usually costs the most to run and can cause the most havoc when it malfunctions.

  • Back in the late 1980s when market drivers created the cost-effective option of using above-ground circular tanks for industrial activated sludge processes, there were some early valuable lessons for both aeration equipment manufacturers and plant operators.

  • The holiday season is a time to gather with loved ones, consider the things we are thankful for, and remind ourselves about what is truly important.

  • Water supplies remain our most valuable and necessary resource. Overused and often contaminated throughout most of history, water was no less of a concern back in the 1600s when the Pilgrims landed at Plymouth Rock than it is for us today.

  • Just like a poorly poured pint of beer can wreak havoc on your coffee table, excessive foam formation in aeration tanks can create operational challenges for both municipal and industrial treatment plant operators. In municipal plants, foam formation is common during secondary treatment startup, as the young microbiology is unable to breakdown surfactants associated with soap, shampoo, etc.

  • People concerned about their water footprint often make an effort to turn the faucet off quickly, take shorter showers, and cut back on watering the lawn.

  • The real MVP in professional football? Water.

  • Election season is in full swing and while it may not be the “hottest” topic being debated amongst presidential candidates, the topic of water isn’t being ignored as we approach November. Several candidates have addressed the challenges plaguing water and wastewater systems nationwide.

  • Choosing a technology provider to supply a solution for water or wastewater treatment is no small task. Frankly, there’s a lot at stake, from large sums of money to the efficacy of an entire operation hinging on the right decision. But with so many options out there, what qualities do you need to look for to guarantee you’re making the right choice? To get an answer, Water Online spoke with Fred Siino from KLa Systems.

  • Summer reading list a bit dry? Drink up these books on the world’s greatest resources — water.

  • Jet mixers are widely used in both municipal and industrial wastewater treatment facilities to blend the plant influent and suspend light organic solids in circular equalization tanks. 

  • Could all wastewater treatment plants someday become energy neutral? The goal may sound unobtainable, but with the right technology, investments, and innovation it may not be. According to the American Biogas Council, the wastewater sector consumes 22 terawatt hours of electrical energy each year, but has the potential to generate 851 trillion BTU of energy annually.

  • While the term “Water Resource Recovery Facility” may seem like nothing more than a trendy phrase, the name change represents a distinct shift in the role that wastewater utilities can now play.

  • While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.

  • We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly  desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.

  • Where there’s a problem, there’s a solution. Sometimes it just takes a little ingenuity to get there. When you’re in the business of providing solutions to municipal and industrial water resource recovery utilities, then it’s helpful to invest in ingenuity.

  • Not all water treatment needs are the same. That’s why it’s imperative to work with those that understand the subtle dif­ferences that make each industry unique. For food and beverage companies, that means aligning with KLa Systems, a com­pany focused on oxygen transfer with a track record of innovation in jet aeration and mixing.

  • KLa Systems has recently completed our 30th MBR aeration system project using our Slot Injector™ aeration technology. These plants are for industrial customers and although predominantly in the food & beverage sector, we have also supplied MBR aeration systems for leachate treatment, chemical and petrochemical processing effluent.

  • With nutrient control becoming more of a concern and prompting ever-increasing regulations, biological wastewater treatment processes must be scrutinized and optimized like never before. To that end, KLa Systems, which specializes in custom-designed mixing and aeration technologies necessary for biological wastewater treatment, answers 10 important questions related to aeration equipment.

  • Many municipalities are facing the challenge of having to equalize large volumes of storm water sometimes mixed with raw sewage in order to continuously meet their permit limitations. The equalized flow is stored during a storm event and then slowly diverted to the treatment facility when influent flows return to normal levels.

  • A gourmet cheese, whey protein, and lactose production facility located in the Midwest had been utilizing a land application system for effluent discharge for over 40 years. Using a combination of ridge and furrow and spray irrigation, the plant had many years of success applying their wastewater to the land.

  • Looking to reduce its water footprint, Shepherd Neame Brewery invested in a complete membrane bioreactor (MBR) wastewater recovery and re-use plant. Learn how the new plant's aeration system has helped to reduce the brewery's water-to-beer ratio to an industry-leading value of 3:1.

  • Since 2001 KLa Systems has supplied innovative jet aeration and jet mixing systems for industry, water utilities, and municipalities around the world. In 2006 we introduced the Slot Injector™ aeration system.

  • A landfill had an existing single basin SBR plant to process the leachate which is notable for its high nitrogen load. The original system was installed with a fine pore diffuser aeration system and due to the chemical/biological composition of the mixed liquor it was prone to diffuser fouling and premature membrane failure.

  • KLa Systems, Inc. has developed a skid mounted Slot Injector™ manifold system for installation into existing basins without the need to take the basin out of service. The directional Slot Injector manifolds can be used in aerated lagoons, oxidation ditches and circular tanks to provide both oxygen transfer and mixing to meet the process requirements.

  • The plant manufactures touch panel and polarizer which are materials for LCD assemblies. Since the manufacturing process is a semiconductor process, the wastewater contains large quantities of organic solvent from developers, strippers and rinse liquid waste. By KLa Systems

  • KLa Systems is in the process of starting up their tenth MBR project using slot injector aeration technology.

  • Anaerobic wastewater treatment processes have been increasing in popularity across the food and beverage industry. Anaerobic processes effectively treat both the normal industrial wastes (higher concentration than municipal wastes) and the very high-strength/low-volume wastes generated by the industry. A welcome side benefit is the generation of biogas for energy production. A food and beverage company can save money, improve sustainability, and lower its carbon footprint. Other drivers include potential legislation in some states to reduce organic waste in landfills and the significant reduction in land application process viability.
