Wastewater treatment - Dewatering Britannica

Wastewater treatment - Wastewater treatment - Dewatering: Digested sewage sludge is usually dewatered before disposal. Dewatered sludge still contains a significant amount of water—often as much as 70 percent—but, even with that moisture content, sludge no longer behaves as a liquid and can be handled as a solid material. Sludge-drying beds provide the simplest method of dewatering.
