Effect of Algal Biofilm and Operational Conditions on Nitrogen Removal in Waste Stabilization Ponds

The possibility of optimizing treatment and reducing land requirement in WSP (Wastewater Stabilization Ponds) is paramount. WSPs are known to provide treatment for wastewater but these have several drawbacks which include short-circuiting, limited area for microbial attachment, oxygen limited to upper aerobic layer and large area for construction.This study proposes investigating ways of addressing these issues by use of vertical baffles. It is expected that vertical baffling will reduce short-circuiting, create more area for microbial attachment, and alter wastewater flow from aerobic to anaerobic zones. The overall effect of improving nitrogen removal is anticipated.
