Dewatering conveyor belts, which may include heat and vibration as well, have perforations in the dewatering conveyor belts that drain water as the sludge is moved. Belt presses squeeze out the water by passing the slurry between a lower dewatering conveyor belt and an upper weighted belt. Screw conveyors, mixing tanks, or similar equipment mix air at a controlled temperature and humidity with the sludge, and water is carried away with the air flow. Dewatering refers to the removal of unwanted water. It may be the removal of ground water, process water, water entrained or carried along by oil or gas, or water used to transport solids. The equipment choice is based on factors such as a permanent versus a temporary operation, a batch versus a continuous process, and the percentage of water that must be removed.

               

Water used to carry a solid is called slurry. Coal slurry pipelines, for example, pipe ground-up coal particles carried in a water stream. Gold panning was another operation that took advantage of the transport possibilities of water. The materials transported by the water are referred to as the solids. Once the solids are concentrated, they are referred to as sludge or cake.

The water may have to be pressed out or the solids filtered out In many slurry operations. Often, agents that promote clumping of the solids, called flocculants, are added to the sludge to enhance dewatering.
