Sludge reduction by mixed liquor ozonationUBC Library
In this comparative study a combination of mixed liquor ozone treatment and an enhanced biological phosphorus removal (EBPR) process with long SRT operations (25 d and 50 d) was tested for sludge reduction. An equivalent to about 80 sludge reduction was achieved in an EBPR system with mixed liquor ozonation and with long SRT operation. The effluent quality was not affected with mixed liquor
