Award-Winning Design Helps WWTP Protect Chesapeake Bay Watershed
9/26/2018
Arlington County’s Water Pollution Control Plant (WPCP) in South Arlington, VA, is located on 35 acres of land squeezed into a commercial/residential neighborhood less than a mile west of Ronald Reagan Washington National Airport. The facility treats flows from nearly all of Arlington. In addition, nearly 20 percent of the plant’s flow comes from neighboring localities such as Alexandria, Fairfax County, and Falls Church. Effluent from the plant is discharged into Four Mile Run to the south, which feeds into the Potomac River and, ultimately, the Chesapeake Bay.

Improving The Quality Of Secondary Wastewater For Indirect Potable Reuse—From Pilot To Full Scale Plant
8/29/2018
In spite of the recent abundance of water, many of California’s aquifers continue to balance on the edge of water scarcity. Decades of overpumping have reduced the amount of ground water available to supplement surface water resources diminished by drought. The Pure Water Monterey Ground Water Replenishment Project (Monterey Pure), addressed the need to replenish a local aquifer, by piloting Advanced Water Treatment (AWT) processes, to determine the best method to convert secondary wastewater into a pure water resource.

BIOSTYR® Improves Health Of The Long Island Sound
6/13/2018
The New Rochelle Wastewater Treatment Plant is located in the Westchester County, New York, discharging to the Long Island Sound. It serves a population base of 65,000 people and is permitted to treat average flows of up to 20.6 MGD. Operating with primary clarification and pure oxygen-based activated sludge treatment since a 1979 upgrade, the plant only removed BOD and TSS from the wastewater.

Bringing An END™ To RO Brine And Difficult Brackish Water Treatment
6/8/2018
Access to clean, safe, fresh water is one of the greatest challenges facing humanity in the 21st century. By some estimates over 1.5 billion people face water scarcity issues that directly threaten their health or economic welfare on a daily basis. More concerning, the impacts of climate change and global population growth are expected to exacerbate these issues to impact over 2.3 billion people by the year 2050. These sobering facts are why six of the United Nations (UN) Sustainable Development Goals (SDGs) are focused on providing access to clean, safe water. Part of solving this challenge is reducing industrial water consumption to conserve water resources.

Put An END™ To Silica Fouling
5/25/2018
Despite the tremendous advancements in water treatment technology over the past several decades, a handful of compounds remain significant challenges. Among the most challenging for water treatment systems is silica which can lead to irreversible fouling in modern (RO) treatment systems. Magna Imperio’s new Electrochemical Nano Diffusion (END™) process offers a simple and cost-effective solution for treatment of raw water and brine streams with high silica concentrations.
