Nutrient Removal Resources

31. AquaDiamond Cloth Media Filters Achieve 0.1 mg/L Total Phosphorus Limit 4/8/2020

    With the current national emphasis on restoring the water quality of America’s urban waterways, the City of Brockton, Massachusetts, Advanced Water Reclamation Facility (AWRF) wanted to stay ahead of the regulatory cycle – in particular, phosphorus discharge limits set forth by the National Pollution Discharge Elimination System (NPDES) program of the United States Environmental Protection Agency (U.S. EPA). For this region of the country, the U.S. EPA has proposed total phosphorus (TP) discharge limits of 0.1 mg/L.

32. Integrated Solutions Drive Resource Recovery And System Resiliency 3/17/2020

    Traditional approaches or wait-and-see tactics, which at times can save the day, too often result in missed opportunities for incremental improvements that could act as building blocks of a long-term strategy. Integrated solutions can reveal this strategy road map for a resilient and reliable water infrastructure system.

33. How To Utilize Electrocoagulation For Efficient Phosphorus Removal In Wastewater 2/24/2020

    In this article, we will discuss what phosphorus is, the effects of elevated phosphorus levels on an ecosystem, and how innovative electrocoagulation technology can be sustainably used for effective phosphorus removal in wastewater and water sources.

34. Your Sewage Is Valuable Muck 2/21/2020

    A world without phosphorus is a world without life. But phosphorus is a finite resource, so researchers are recovering it from sewage.

35. Technologies To Meet Smaller Footprint And Stringent Nitrogen And Phosphorous Requirements 2/5/2020

    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.

36. Sidestream Enhanced Biological Phosphorus Removal Made Easier 1/21/2020

    Some excellent progress has been made in recent years on sidestream enhanced biologic phosphorus removal, but a current project promises to advance the practice even further.

37. AquaSBR® System Treats High Strength Vegetable Processing Waste 1/15/2020

    In early 1993, Birds Eye Foods was faced with a difficult decision, to construct a new wastewater treatment facility or to retrofit their existing flow-through extended aeration treatment system

38. Increased Energy Savings Achieved By Improved Design And Rigorous Testing 10/30/2019

    In 2017 Aeration Industries provided its Tri-Oval system with three Triton aerator/mixers controlled by dissolved oxygen instrumentation to a municipality located in Tennessee.

39. Aeration And Mixing Bring Hussain Sagar Lake's Ecosystem Back To Life 10/30/2019

    Hussain Sagar Lake in India faced an inflow of untreated waste and pollution causing decreasing DO levels and foul odors in the nearby community.

40. Nutrient Sensor Action Challenge Winners: Data And Decisions To Manage Excess Nutrients 10/22/2019

    Nutrients in the environment from excess nitrogen and phosphorous can result in negative impacts on water quality. EPA is improving nutrient management by incentivizing the development of low-cost technology solutions, such as nutrient sensors, in collaboration with USGS, USDA, NIST, NOAA, and the U.S. Integrated Ocean Observing System (IOOS).
