Location of the thickener in a wastewater treatment plant is important. If sludge is to be digested, thickening a blend of primary and waste activated sludge is a good practice. If these sludges are to be dewatered, then they should be thickened separately and mixed immediately before dewatering [3]. Sludge Thickening vs. Dewatering

Continous gravity settling simulates a thickening chamber and is thus much more representative of the real operation. In studying the process of thickening, two types of continuous thickeners may be used: Laboratory columns varying from 0.5 - 2 ft. in diameter, and …

Thickeners are a major component in a plant layout and their selection may be critical for several reasons: They occupy large spaces as may be seen from the aerial photograph of three large thickeners. They are normally positioned far away from the center of the plant and owing to the large flows they are fed by gravity to save pumping. ...
