Alkaline treatment of excess activated sludge

Alkaline decomposition of excess waste sludge was attempted. Effect of sludge concentration, alkaline concentration, sludge volume index (SVI) and temperature on digestibility of the sludge were investigated. Digestibility was increased with increasing alkaline concentration and temperature and decr...

Summary:Alkaline decomposition of excess waste sludge was attempted. Effect of sludge concentration, alkaline concentration, sludge volume index (SVI) and temperature on digestibility of the sludge were investigated. Digestibility was increased with increasing alkaline concentration and temperature and decreased with sludge concentration and SVI. Digestibility was related with treatment time by the following equation; X=AtB
