Thickening is usually accomplished in a tank called a gravity thickener
Definition of Activated Sludge Treatment Activated sludge treatment can define as the wastewater treatment plant, which eliminates the particulate matter like sand, unwanted inorganic and organic wastes and harmful microorganisms from the sewage waste. The process is followed by the primary, secondary and tertiary treatment methods sludge moisture content, retention time, etc., and is based on the solids balance of the entire sludge treatment facility. The solids balance considers the reduction due to gasification, return load from each facility and the increase due to addition of chemicals, etc. This is important for sizing the sludge treatment units In municipal wastewater treatment AD is most often used to treat the waste solids discharged from the activated sludge-based process [links to YouTube.com], both the primary and the secondary (waste activated) sludge streams.

SLUDGE HANDLING, TREATMENT AND DISPOSAL 1. GENERAL CONSIDERATIONS. Sludge, or residual solids, is the end product of wastewater treatment, whether biological or physical/chemical treatment. Primary sludge is from 3 to 6 percent solids. Treatment objectives are reduction of the sludge and volume, rendering it suitable for ultimate disposal an activated sludge treatment process. It is here that biological oxidation of dissolved and fine suspended organic matter takes place. The biological oxidation takes place because aerobic microorganisms, organic matter and dissolved oxygen are all brought together in the aeration tank. The organic matter comes in with the primary effluent. Th Sludge treatment and disposal. 1. Romanus Peter BEHP1109 1442. 2.
