Parkson Corporation is pleased to announce the release of the latest video in the Parkson University series, “Sludge Thickening – How Our Industry Has Been Calculating Polymer Usage Wrong.” In this video, we discuss how to correctly calculate polymer use during the sludge thickening process in wastewater treatment.
On December 11th, the U.S. Environmental Protection Agency (EPA) and the Department of the Army (Army) proposed a new definition of “Waters of the United States” to replace the 2015 definition adopted under the Obama administration. That definition has been subject to a variety of litigation over the past three years, causing its application to be sporadic at best.
Water utilities in Michigan are suing the state over the implementation of the toughest lead rules in the country.
Basic construction activities today are more complex than ever when it comes to environmental concerns. Dewatering is a common necessity for contractors and developers today. In addition to ensuring a safe construction site, contractors must be aware of groundwater disposal constraints and regulations.
A commercial real estate corporation that owns, develops and operates premier properties in major North American cities was one of the earliest companies to recognize the benefit of individually metering tenants for their utility usage. When designing a prestigious building complex in New York City, the company sought a flow meter that would facilitate this task. After careful consideration of several options, the choice became clear: clamp-on ultrasonic flow technology from Siemens.
At one of the most prestigious universities in Asia, the main campus comprises a large number of buildings clustered within an area less than 2 km2 (1.2 mi2). Because the university was built more than a century ago, many facilities on the campus were never fitted with the proper instrumentation for energy measurement, making it difficult or impossible to monitor the performance of most HVAC systems, including the cooling system.
After having been reluctant of using clamp-on ultrasonic flow meters for energy measurement in cogeneration plants in large residential and commercial buildings, a USbased engineering firm was convinced by the clamp-on meter’s strengths.
Mixing is something that is often taken for granted when designing systems for water and wastewater treatment. Perhaps “taken for granted” is too harsh a term. Let’s instead say that while designing a treatment unit operation or process, mixing as a phenomenon is automatically assumed to occur — an assumption that forms the basis for process controls, performance guarantees and measurement methods and locations.
Did you ever have a paper route or go door-to-door selling items to your neighbors for a charitable cause in your younger years? Remember the house with the big dog? Or the overgrown yard? Maybe even the dark house at the end of the lane that the spooky old woman known to all as “the witch” lived in?
Combining technologies can deliver a detailed and robust understanding of flood risk.
The video provides a different perspective on the sludge thickening process and explains how various features combine to make the ThickTech the best option for low polymer usage and the highest capture rates of 98% or more.
Most people understand the inherent benefits of plastic piping — chemical resistance, installation speed, ease of assembly, cost efficiency, longevity in corrosive, harsh exterior or underground environments, etc. Not everyone, however, fully appreciates the nuances of plastic piping design that help to maximize those benefits most efficiently.
Las Vegas water planners are prepping for a harrowing possibility: The disappearance of the Colorado River.
Harmful algal blooms — the overgrowth of algae in water — are a major problem across the nation. Blooms occur when excess nutrients (nitrogen and phosphorus), combine with sunlight, and warm temperatures in water bodies. They can cause severe, negative impacts on aquatic ecosystems, the economy, and human health.
While San Diego has a reputation for beautiful weather in a sunny seaside setting, its growing population in the southernmost area of rain-starved California is a recipe for trouble in paradise. That challenge has spurred the creation of Pure Water San Diego — a multi-phase, multi-year program with the goal of using recycled water for up to one-third of San Diego’s water supply by the year 2035.

Newfoundland’s Department of Municipal Affairs and Environment has added an interesting condition to its approval of Grand Falls-Windsor’s $10-million wastewater treatment facility upgrade. As reported in The Compass, the town must develop a Women’s Employment Plan for the construction phase of the project.
Envision a world absent of a water crisis, an end to the threatened health and economic welfare affecting nearly 1.5 billion people due to water scarcity. Clean, safe, fresh water is one of the greatest challenges facing humanity in the 21st century and we are only scraping the surface on achieving public awareness. As our global population increases, access to clean water decreases; a metric with diminishing returns.

Matthew Au of Las Vegas Valley Water District describes using AF Transformer to speed up AF structure creation to build a better database.
Like wastewater treatment plants across the country, Village Creek Water Reclamation Facility experiences fluctuations in the volume of water to be treated due to the inflow and infiltration of stormwater. During storm events, this variation can be between X and Y mgd.
Not cool enough in summer. Not warm enough in winter. Guests staying at a prestigious country club in New York state complained regularly about the air conditioning and heating of their luxury suites and apartments. The geothermal heat exchange system serving this facility had never, in fact, been fully functional.
Across the country, farmers face unrelenting pressure to conserve both water and energy. From California to Texas, recent droughts and declining groundwater levels require more pumping to provide irrigation water for crops. Pumping water takes energy, as do many other precision agriculture tasks involved in running a successful farm today. This symbiotic relationship between water and energy use — often called the energy-water nexus — is taking its toll on America’s agricultural industry.
Dr. Francisco Castillo speaks on their FIELD MOUS system (Field MOnitoring User System), where a PI System acts as a repository of technical data into which different departments plug their data, and other departments access it to fit their particular needs.

The characteristic feature of the HUBER Drum Screen LIQUID is its screen basket which is horizontally installed in the channel or in a tank.
In the discussion about limited resources and energy saving in sewage treatment plants innovative sewage treatment methods are increasingly becoming a focal point. In Germany, there are about 1,200 sewage treatment plants which are designed for 10,000 to 50,000 PE, about one third of them have a sludge digester. Thus, there is a potential of about 800 sewage treatment plants that remains for a change from aerobic sludge stabilisation to processes with anaerobic sludge stabilization.
One of the nation’s largest four-service utility providers, Colorado Springs Utilities supplies energy and water to over 450,000 people. The state-certified laboratory of the Water Quality Assurance section processes over 14,000 samples and 80,000 analytes per year from eight watersheds, seven finished water treatment facilities, 38 finished water reservoirs, four post-chlorination stations, two wastewater treatment facilities, and over 2700 miles of pipeline.
With the proliferation of sensors, data collection, and cloud storage, there is the potential for operational insight heretofore never available, and the opportunity will only expand as the technology evolves and the Internet of Things becomes, well, more of a thing. But data is only truly useful if it informs decision-making that results in positive impact — for an organization's bottom line, its personnel, its customers, or even the world at large (i.e., the environment).
Colorado Springs Utilities internal customers can see lab results more quickly and as a result are reducing costs by optimizing their facilities by 30%.

Filtration has been around for a long, long time, so it may be that most treatment plant operators feel pretty informed about its capabilities. But hearing from Brian Frewerd, Director of Application Engineering with Parkson Corporation and Water Talk guest, will likely prove enlightening. Frewerd provides background on sand filtration for tertiary treatment applications, followed by insight on notable technology improvements and performance milestones
