Upgrading Lagoons to Remove Nitrogen & Phosphorus

Description:Due to increased concern across North America regarding the health of lakes and rivers downstream of municipal and industrial wastewater treatment plants (WWTP), improving water quality from existing WWTP (as well as new processes) has become a high priority. Historically, most lagoon systems were designed to remove BOD and TSS from the wastewater stream. Increased focus on the effect of effluent toxicity in the receiving stream, along with possible eutrophication of lakes and rivers, has resulted in new requirements for nitrification of ammonia, and removal of both phosphorus and nitrogen. Lagoon Phosphorus removal is accomplished by chemical addition and filtration. While phosphorus removal is an established process, ongoing development work continues to lower chemical dosing requirements and improve removal efficiencies when utilizing the process to upgrade lagoon systems.
