ENHANCED BIOLOGICAL PHOSPHORUS REMOVAL IN A CANNIBAL™- TYPE ACTIVATED SLUDGE PROCESS
Abstract
A Cannibal™ solids reduction process was simulated in bench scale to test the feasibility to simultaneously achieve enhanced biological phosphorus removal (EBPR) and a reduction in sludge production. The biomass yield in the Cannibal-EBPR system was estimated to be 0.15 mg VSS/mg COD, which represented a 32% reduction in solids production compared to a Control-EBPR system operated with a 10-day solids retention time, for which conventional digestion of excess sludge was assumed. Regarding EBPR, greater than 98% phosphorus removal was sustainable in the Cannibal-EBPR system, but a mass balance on total phosphorus could not be closed, with nearly 33% of the phosphorus unaccounted.
