WebbCalculation : The daily sludge mass produced = ( 100,000 ) ( 0.080 ) = 8,000 kg dry SS / day. Since 97 % MC is 3 % SC or approximately 30 kg dry SS / m 3 sludge, the daily volume produced is 8,000 / 30 = 267 m 3 . The digester ( liquid ) volume is ( 267 ) ( 25 ) = 6,680 m 3 ( probably divided equally between two digester tanks ). WebbThe solids content of mechanically dewatered sludge typically ranges from 20 to 45 percent solids by weight; most processes produce con-centrations of solids at the lower end of that range. Conditioning Sludge conditioning processes do not, in and of themselves, reduce the water content of sludge.
