Webb16 juni 2024 · Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the separation of the solids and liquid. Webbh 1: clarified water zone. h 2: separation or free sedimentation zone. h 3: sludge storage zone (safety precaution during rainfall episodes), linked to the flow of deconcentrated matter from the aeration tank. h 4: sludge thickening and discharge zone.. The sum of the four figures hm = h 1 + h 2 + h 3 + h 4 represents the structure’s average depth. For a …
