Excess nutrients in coastal areas cause severe damage to the marine environment through algal blooms, eutrophication, ocean ‘‘dead zones,’’ and a reduction in biodiversity. Nutrients typically find their way to the ocean through wastewater discharges or agricultural runoff. Since many U.S. coastal water resource recovery facilities have not been designed with nutrient removal processes, excess nutrients in wastewater discharges in these regions contribute to harmful environmental conditions. One very promising technology to combat this issue is anammox (anaerobic ammonia oxidation), which has been shown to reduce nitrogen in wastewater sidestreams in full-scale installations and has been demonstrated in mainstream process configurations.
This webcast presented the results of the project Nitrogen Reduction Solutions for Ocean Discharges (5117), which identified and piloted four technologies that promote anammox for removal of nitrogen during wastewater treatment.
