Abstract | Physical-chemical treatment of raw wastewater in a 50,000 to 100,000 gpd pilot plant consisted of two-stage lime precipitation with intermediate recarbonation, filtration, pH control, ion exchange or breakpoint chlorination for nitrogen removal and carbon adsorption. The complete system with ion exchange removed 98% of the phosphorus, 95% of the organics (COD) and 78% of the total nitrogen. With breakpoint chlorination, the complete system removed approximately 98% of the phosphorus, 94% of the organics (COD) and 86% of the total nitrogen. (Modified author abstract) |
