WebThe density of dewatered cakes ranges from 15% to 40%. The thinner cake is similar to a wet mud, while the latter is a chunky solid. The method of ultimate disposal and economics dictate the degree of moisture reduction necessary. Waste solids production in primary and secondary processing can be estimated using the calculation bleow. WebDry, high solids cakes mean lower costs. Use of dewatering equipment is an effective tool for managing sludge accumulation, reducing both transportation costs and storage expenses. Consistent Cake Dryness with Lower Risk of Spilling/Leaking Use of sludge dewatering filter presses produces consistent cake dryness.
