Rotary drum thickeners

Rotary drum thickening increases the sludge solids concentration by agitating the solids in a slowly-rotating cylindrical drum with porous walls though which the water (or filtrate) drains. The drum is normally 0.5−1.5 m diameter drum and rotates at speeds between 5 and 20 RPM while the sludge continually passes along its axis.
