اقرأ أكثرResultSludge Thickening. The primary stage in reducing the sludge volume is thickening. When the thin sludge is condensed, thick sludge is formed. The viscosity of dense sludge is greater, however it should likewise be pumpable. The suspended solids content of the thickened sludge to be pumped to the dewatering …
اقرأ أكثرResultThe air to solids ratio is the mass of air employed per unit mass of sludge solids. For sludge thickening applications, this ratio is normally in the range 0.02−0.06 kg air/kg DS. The concentration of air in the recycle stream is determined primarily by the pressure, since gas concentration increases with pressure. ...

اقرأ أكثرResultSludge is introduced at the central feed well and the supernatant overflows a peripheral . The sludge is thickened by the action of a specially designed rake which also moves the thickened sludge to a central hopper, of included angle 60°, for intermittent discharge under hydrostatic head (Albertson, 1992 ).
اقرأ أكثرResultA rotary drum thickener (RDT) is based on the same principle as a gravity belt thickener (GBT), in that water drains from the sludge through a retaining porous medium. For an RDT the porous medium is the cylindrical wall of a 0.5−1.5 m diameter drum which rotates at speeds between 5 and 20 RPM while the sludge …

اقرأ أكثرResultFor U.S. units, the flow rates in the equation will be in MGD and the suspended solids concentrations will be in mg/L. A factor of 8.34 will be needed with each term to convert mg/L to lb/MG, resulting in lb/day for each term. Since we are going to solve the equation for Qr, the 8.34 in each term will 'cancel out.'.
