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. Webb• This calculation can be applied to either neat polymer or polymer solution. For example, in U.S. customary units: • If the desired polymer dose is 10 active lb/dry ton, the flow rate to a rotary drum thickener (Solids Flow Rate) is 350 gpm, the rotary drum thickener feed solids concentration (Solids Concentration) is 0.75%, and Webbper day and the pounds of activated sludge or secondary efﬂuent solids discharged per day (Equation I.6). (I.6) The MCRT of an activated sludge process can be calculated by dividing the pounds of suspended solids or MLSS in the activated sludge process by the pounds of suspended solids leaving the activated sludge process (Equation I.7).The MCRT the port jefferson
