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.

Jun 16, 2019· Meaning Activated Sludge Process. The activated sludge process is one of the biological method of industrial waste waste treatment. The activated sludge process consists of converting the suspended and particulate organic matter in the raw waste water into harmless end products and new cells growth with the help of Anaerobic and Aerobic Microorganisms.
Activated sludge is also the name given to the active biological material produced by activated sludge plants. Excess sludge is called "surplus activated sludge" or "waste activated sludge" and is removed from the treatment process to keep the ratio of biomass to food supplied in the wastewater in balance.
