Clarifier Wikipedia

Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and/or thickening Concentrated impurities, discharged from the bottom of the tank are known as sludge, while the particles that float to the surface of the The result of this continuous development is the Flottweg Cseries HTS Decanter ® They are used in sludge dewatering for flow rates from 5 to 180 m³/h Flottweg has developed a unique centrifuge concept specifically for the highlevel dewatering of sewage sludge: the Flottweg Xelletor seriesSewage sludge dewatering sludge thickening Decanters
