    Keeping up with both the water needs and sewage disposal of the Santa Margarita Water District has come with significant challenges, particularly due to both the increase in influent and change in the makeup and durability of the sewage running through the district’s reclaimed-water facility.

  • EPA Researchers Explore Technology To Destroy PFAS

    Per-and polyfluoroalkyl substances, otherwise known as PFAS, are a large group of human-made organic compounds with properties that make many of them toxic and persistent in the environment. PFAS have been manufactured and used since the 1940s in items such as fire-fighting foams, adhesives, cosmetics, paper products, and stain and water repellants. Until now, researchers have been unable to destroy PFAS in a way that has potential for larger scale use. 

  • Technologies To Meet Smaller Footprint And Stringent Nitrogen And Phosphorous Requirements

    The Buxahatchee Wastewater Treatment Plant in Calera, Alabama was built in 1960. It upgraded in 1985 to a 0.75 MGD capacity extended aeration system with integrated clarifier and traveling aeration bridge for nitrification.

  • Reaping The Benefits Of Proactive Asset Management

    The more a water distribution or wastewater collection operation knows about its infrastructure, the better equipped it is to optimize performance, maximize asset life, and prioritize long-term capital investment. Here is a breakdown of enterprise asset management (EAM) opportunities and the advantages they offer — from more timely data collection, to more in-depth cost analysis, to more cost-effective decision-making.

  • Mapping Assets For Resilience And Response In Emergencies

    Among utilities concerned about resilience and response in natural disasters or other emergencies, precise asset inventory and mapping are high priorities. In truth, there is value in having the same information for everyday purposes as well. For anyone who has ever had a problem locating or tracking key water or wastewater system assets, here are several good reasons and ways to avoid a last-minute scramble.

  • CHA Consulting Is Helping Florida Utilities Meet Ambitious Reclaimed Water Effluent Regulations

  • Ultrasonic Metering For Small Water Meter Applications

    For many years, ultrasonic metering has been utilized for large scale liquid and gas measurement. However, it is a relatively new technology for small meter applications — particularly those designed for potable water.

  • Filter Technology Saves Colorado Plant 50,000 GPD

    Combined with the installation of the new filter media and wash troughs, this particular type of underdrain and media retainer brought the water treatment plant’s operations up to speed.

  • $0 CAPEX Model Aids Innovation In Changing Water Environments

    Managers of industrial, municipal, and agricultural water quality or water use monitoring can attest to the challenges of balancing depth of detail against the costs of achieving it. Now, an Infrastructure-as-a-Service (IaaS) business model is rewriting the economic impacts of those challenges by repackaging water monitoring capabilities to meet evolving needs more efficiently.

  • How To Design A Solution For A Temporary Water Or Vapor Treatment Project

    The key to a successful water treatment or vapor extraction project is to understand the elements that can impact the treatment process, as well dispelling key myths about temporary treatment systems.

WASTEWATER APPLICATION NOTES

  • Microbial Control In Cheese Making

    Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

  • Application Note: Simultaneous Determination Of Total Bound Nitrogen (TNb) And Total Organic Carbon (TOC) In Aqueous Samples Total bound nitrogen (TNb) consists of dissolved ammonia, nitrates, nitrites, amines, and other organic nitrogen-containing compounds. TNb measurements represent an alternative to Total Kjeldahl Nitrogen (TKN) analysis for rapid screening of industrial wastewater, drinking water,agricultural run-off, and surface waters.

  • Waste Technologies Transform Problems To Profit

    Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.

  • Bringing Efficiency And New Confidence To BOD₅ Analysis

    Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

  • Reduce SBR Maintenance Costs With Jet Aeration

    Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

  • Process Optimization For Flow Measurement

    The Saalfeld-Rudolfstadt Association in Germany must rely on cutting-edge technologies that optimize flow measurement in order to allow for smooth processes and supply 82,000 inhabitants with clean drinking water. 

  • Advances In Paper-Based Devices For Water Quality Analysis

    Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.

  • Recording & Control: Online Data Recording And Control In Anaerobic Digestion Processes

    Solids present in wastewater need to be safely and comprehensively treated and removed. This means not only removing toxic compounds, including both organic and inorganic materials such as heavy metals, but also eliminating any harmful bacteria present in the solids.

  • Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money

    Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

  • Pile Cloth Media Filtration Effectively Removes COD And TSS From Oil Refinery Wastewater

    This application profile focuses on two test sites with different treatment requirements and describes how Aqua-Aerobic Systems’ OptiFiber® pile cloth media filtration was used at both sites to address the removal of harmful constituents from refinery wastewater.

Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

A tube diffuser BIOFLEX® consists of a support tube with an inside thread and slotted sleeve membrane. Two hose clamps fasten the membrane onto the support tube and an O-seal is applied for sealing between the distribution pipe and the diffuser element. To avoid buoyancy the support tube is flooded. Tube diffusers are usually installed in pairs either by a pipe clamp fixed on a round tube serving as a distribution pipe or by a double nipple inserted into a rectangular tube. When air is supplied, it is directed through the head of the support tube under the membrane. Through the slots of the membrane the air is smoothly dispersed into the wastewater.

Iron salts are a proven technology for long-duration hydrogen sulfide control in collection system gravity and forcemains; solids processing units, solids transfer lines and anaerobic digesters. They have been used for over 30 years in hydrogen sulfide control applications and are a well understood technology.

Biological Nutrient Removal (BNR) is a process used for nitrogen and phosphorus removal from wastewater before it is discharged into surface or ground water.
