Typically, sludge is thickened (dewatered) to reduce the volumes transported off-site for disposal.A volume reduction of approximately 30 - 80 % can be reached with sludge thickening before further treatment. The sludge is compressed at the tank bottom only by the force of gravity, while above the sludge a cloudy water layer is formed, which is taken off and led back into the inlet.
