Overview
The well documented effect of nitrogen and phosphorus on eutrophication and increased oxygen demands are the primary drivers for regulatory efforts to reduce discharge limits for phosphorus and nitrogen in wastewater effluent. Aquatic and public health implications of nutrient discharge affect over 80 bays and estuaries and thousands of rivers and streams in almost every state of the nation. Ongoing implementation of federal and state water quality standards and total maximum daily loads will further reduce nitrogen and phosphorus limits for wastewater treatment facilities, making it imperative for engineers to understand the technologies available to reduce these nutrients in wastewater effluents.
This course covers phosphorus removal by chemical addition, biological nitrogen removal, combination processes, effluent filtration, mathematical modeling of removal efficiency, nutrient removal in small and decentralized systems, and nutrient recovery. The course is based on the EPA document EPA/600/R-09/012.
