Sidestream Management to Optimize WRRF Nutrient Removal
Internal recycles, such as reject water and sidestreams from solids processing WRRFs can impact nutrient removal efficiency as well as create nuisance conditions. Managing these recycles can improve nutrient removal performance and reliability and reduce costs. Reject water treatment can also be used to reduce the nutrients discharged from a secondary treatment plant. This webcast reviewed the various recycles, their composition, and impact on the mainstream process. Strategies to optimize performance and to reduce nutrient discharge and reduce operating costs will also be presented.
