WebDewatering. 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. Web15 feb. 2024 · Sewage sludge, formed by bacteria as a result of the consumption of organic pollution, arises as a by-product of waste water treatment. A range of treatments allow the safe disposal of the sludge. Liming and aerobic or anaerobic digestion stabilise the sludge, avoiding odour and reducing pathogenic organisms.
