• Summer Road Trip Finds Small Streams Have Big Impacts On Great Lakes

  In the summer of 2018, Rob Mooney, a graduate student at the University of Wisconsin–Madison’s Center for Limnology, set out on an epic road trip around Lake Michigan. Mooney was no stranger to the drive. In fact, he had already completed eight circuits of the lake over the previous two years as he monitored seasonal changes in dozens of rivers and streams flowing into the lake.

• SFPUC Leads National Partnership In Shaping Onsite Water Recycling Opportunities

  Reimagining urban water systems demands collaboration, consistency, and crosscutting ideas. Utilities have an important leadership role in actively promoting integrated water resources management and building an enabling environment for water supply diversification.

• Growth Opportunities Are On The Horizon In The Water And Wastewater Treatment Equipment Market As Public Concern On PFAS Rises

  Per- and polyfluoroalkyl substances (PFAS) are a family of ever-expanding, complex man-made compounds that have leached into our soil, air, and water. There are nearly 5,000 different types of PFAS found in various products like nonstick cookware, food packaging, cleaning supplies, paints, waterproof jackets, firefighting foams, carpets, and more.

• Municipality Looks To Expand Plant Capacity While Reusing Existing Systems

  Sharjah Municipality of the Untied Arab Emirates (U.A.E.) was requiring to treat more and more flow despite having very little space for new treatment systems. They were looking at wanting to expand their plants No. 4 & No. 5 plants to meet new total nitrogen limits and try to do so by having to reuse the existing systems. This type of upgrade would save on cost as well as space at the plant.

• Water Stressed City Looks At Opportunities To Reuse And Recycle Tertiary Treated Municipal Sewage For Cooling Tower Application

  Bengaluru, being a water stressed city, was looking at opportunities to reuse and recycle of tertiary treated municipal sewage for cooling tower application in a nearby power plant. Jakkur STP, being a 10 MLD plant based on conventional anaerobic + conventional activated sludge, was identified to supply about 15 MLD of recycled water for the power plant. The entire plant was designed and retrofitted as two process trains of 7.5 MLD. Read the full case study to learn more about why Integrated Fixed Film Activated Sludge technology (IFAS) was determined to be the best suitable upgrade.

• IFAS System Produces High Quality Effluent In East Central Kansas

  The City of Emporia, in East Central Kansas, recently experienced an increase in population and more stringent effluent permit requirements resulting in a strained wastewater treatment plant. Emporia retained the services of a local engineering firm to evaluate the current and future needs of the system and recommend an economical, sustainable, and effective solution. After evaluating several options, World Water Works’ Integrated Fixed Film Activated Sludge (IFAS) conformed to all the requirements and was selected.

• Profile II Analytical Results, Mine Site Processing

  Increasing profitability through efficient tailing and pregnant solution processing. 

• New Technology Makes Wastewater From Oilsands Safer For Fish

  In the northeastern corner of Alberta, nestled among the expanses of forests and wetlands, lies a major freshwater dilemma that Canada is currently facing. The reuse of water for oil extraction causes tailings ponds to accumulate higher and higher concentrations of harmful contaminants. As such, the water in these tailings ponds is dangerous, and often lethal, to birds, fish, frogs, and plants.

• CyAN App Used For Early Detection Of Harmful Algal Blooms

  Algal blooms with the potential to harm human health or aquatic ecosystems are referred to as harmful algal blooms. The most effective way of protecting public health from harmful algal blooms (HABs) is knowing ahead of time to avoid water containing cyanobacteria, which is why EPA developed the Cyanobacteria Assessment Network mobile app, an early warning indicator system for algal blooms in U.S. freshwater systems, which allows local water quality managers to proactively plan for cyanobacteria harmful algal blooms in their community.

• After 50 Years, EPA Researchers Are Still Using WASP Water Quality Model

  The Water Quality Analysis Simulation Program (WASP) is one of the most widely used water quality models in the United States and the world. WASP has seen continuous development and use since its release in 1970s, with researchers across the world still using the model today.
