What is the Sludge Thickening Process in Water Treatment

Mar 06, 2018 · These particles form a blanket of sludge on the surface that you can remove and treat. Rotary-drum thickeners are stainless-steel drums with spirals and a flow system used to treat solids. The drum mixes sludge to reduce the water content, leaving a solid concentration behind. Water flows out of the drum for reuse.
