Nutrient Removal Resources

1. Cyanobacteria’s Game Of Blooms: Fast Track Or Endurance Run? 8/10/2023
   Just like humans have the freedom to make life choices, cyanobacteria also possess their own unique survival strategies. Groundbreaking research conducted by Griffith University's Australian Rivers Institute unveils the fascinating world of cyanobacteria and how they employ phosphorus storage to thrive.
2. How An Algal Metabolic Hack Threatens Our Waters 3/9/2023
   Algae's ability to adapt and thrive is bad news for U.S. waterways, highlighting the importance of preventative measures to stave off harmful algal blooms.
3. Proactive WWTP Design And Innovation Improves Health Of Chesapeake Bay Watershed 2/2/2023

   Read about the $568 million, decade-long upgrade of a Water Pollution Control Plant that would expand the plant’s capacity from 30 mgd to 40 mgd while also reducing nitrogen and phosphorous to the limit of technology.

4. Evoqua's Orbal System For Biological Nutrient Removal 1/30/2023

   Discover how a fast-growing community's new WWTP meets new tighter limits on ammonia, phosphorus, and nitrogen for future growth.

5. When Density Is Desirable 9/9/2022

   Infrastructure intensification through densification and granulation can help utilities meet nutrient management goals with minimal investment through retrofit.

6. Sustainable Clarification In Food And Beverage Operations 8/5/2022

   Companies within the food & beverage industry generate significant quantities of wastewater each day. For example, a 16 oz. can of beer is about 90-95% water; however, to make that can, beer producers utilize approximately 7 times this quantity. About 2/3 to 3/4 of the water is typically discharged as wastewater to a municipal sewer system.

7. To Reduce Harmful Algal Blooms And Dead Zones, The U.S. Needs A National Strategy For Regulating Farm Pollution 7/18/2022

   Midsummer is the time for forecasts of the size of this year’s “dead zones” and algal blooms in major lakes and bays. Will the Gulf of Mexico dead zone be the size of New Jersey, or only as big as Connecticut? Will Lake Erie’s bloom blossom to a human health crisis, or just devastate the coastal economy?

8. Biotechnology Innovations Extend Life, Resilience Of Wastewater Infrastructure 5/4/2022

   In the daily rush to ensure that all the mechanical, electrical, and operational procedures are followed — monitoring inflow volumes and organic/nutrient loads; servicing and maintaining motors, pumps, and other electrical and mechanical equipment; maintaining chemical treatments to ensure effluent compliance — it is too easily forgotten that wastewater treatment is primarily a biological process.

9. EPA Researchers Develop Tool That Helps Water Quality Managers Meet Nutrient Load Targets 2/15/2022

   Nutrient pollution is one of America’s most widespread, costly, and challenging environmental problems. This pollution can occur when excess amounts of nutrients, such as nitrogen and phosphorus, run off from land into streams, rivers, lakes, and other water sources. To help water quality managers reduce nutrient pollution, EPA researchers developed the River Basin Export Reduction Optimization Support Tool (RBEROST), a regional online tool currently available for the Upper Connecticut River Basin that provides low-cost solutions to meet nutrient load targets.

10. Optimizing The Biological Process With Claros Process Management 9/28/2021

    The Wastewater Treatment Plant of Barstow, California (USA), sits in a challenging geographic and demographic position on a straight line between Los Angeles and Las Vegas. Operating a biological nutrient removal system, the plant treats 2.1 million gallons of water per day and discharges into percolation ponds. Kody Tompkins is the Chief Plant Operator of the facility.
