The use of the chamber filter presses in the purification of concrete slurry or cement residue water

Filter presses are generally used to separate solids from liquids and were used to dewater sludge in England about 130 years ago. Today there are different types of filter presses, such as the frame filter press, the membrane filter press, the chamber filter press. The chamber filter press is used for the purification of wastewater from the concrete industry and thus the separation of water and cement residues. Some of the substances recovered from the aggregate separation can be reused.
