What is dewatering?
The basic answer would be the process of removing water from sludge. This is not a totally correct answer, since dewatering does not completely remove the water from the sludge. The percent of solids and moisture in relation to each other after dewatering, is dependent on the nature of the sludge and the exact natural, chemical, and mechanical means used to dewater the sludge. Therefore, a better definition of dewatering is; the process of natural, chemical, or mechanical removal of water from sludge, thereby reducing it to a damp solid with the lowest level of moisture attainable by the best available technology.
