GLRPPR Sector Resource: Case Studies on Implementing Low-Cost Modifications to Improve Nutrient Reduction at Wastewater Treatment Plants

Title:
Case Studies on Implementing Low-Cost Modifications to Improve Nutrient Reduction at Wastewater Treatment Plants

Abstract:
As many studies have shown, nutrient pollution is one of America's costliest and most challenging water quality problems. However, many of the nation's waste-water treatment plants (WWTPs) were not designed for nutrient removal and major retrofits may be a significant hurdle. The recent EPA draft report showcases a number of communities that were able to achieve better nutrient treatment at WWTPs through relatively low-cost modifications without requiring costly infrastructure upgrades. Nitrogen discharge levels in 12 case study plants were reduced by about 20 to 70%. Two case studies also documented low-cost phosphorus reduction of 40 to 58%. In many cases, these facilities also reduced energy consumption and lowered operational costs. The webcast will give listeners a broad overview of the report, and will highlight two of the case studies in Crewe, VA and Victor Valley, CA.
