Sludge treatment − centrifugal thickening | Sludge Processing
Basket centrifuge. A basket centrifuge is based on an upright rotating vessel (or basket) which can be either perforated or solid, with the solid basket type being the most widely used of the two in sludge thickening. The feed is continuously introduced into the centrifuge while the liquid ( centrate) is removed via an overflow weir.
Sludge Digestion/Thickening Optimizes Treatment
Sludge digestion/thickening occurs in one basin with the use of an Aire-O 2 Tritons aerator/mixer. The equipment aerates to achieve significant volatile suspended solids (VSS) destruction, as well as consistent treatment from mixing. To decant, the equipment is turned off and the solids settle to the bottom allowing the supernatant to be removed.
