Dewatering in its simplest definition, is the removal of water.
In wastewater treatment, dewatering is the part of the process whereby sludges are reduced in volume and converted from a liquid to a solid product. Biosolids dewatering typically occurs when transportation and storage costs for large volumes can be reduced or when the material is destined for landfill or beneficial reuse. The biosolids dewatering process not only effects the volume but also the nutrient and odour levels of the material.
