They can produce much thicker sludge than gravity belt thickeners or rotary drum thickeners, but this benefit comes with additional costs. Centrifuges require significantly more power since they operate at high speeds to dewater the biosolids.

Webbdrum thickener (Solids Flow Rate) is 350 gpm, the rotary drum thickener feed solids concentration (Solids Concentration) is 0.75%, and • If the active content of neat polymer (Active Neat Polymer Concentration) is 40%, then, using the equation provided, the Polymer Solution Flow Rate is calculated to be 0.03 gpm, or 1.8 gph. Webb6 juli 2024 · The sludge sampling technician, in speaking with plant operators, discovered their intent to use effluent water mixed with polymer in a new drum thickener. The technician altered his sampling point to the effluent and used it in the analysis, making it as realistic as possible. Webbof 4% solids, then a fivefold decrease in sludge volume is achieved [1]. Thickening is generally accomplished by physical means including co-settling, gravity settling, flotation, centrifugation, gravity belt, and rotary drum [1].
