CHAPTER 3 SLUDGE THICKENING - Marmara Üniversitesi

SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8% solids, can be thickened to a content of 4% solids, then a fivefold decrease in sludge volume is ...

operating principle sludge recirculation settling. Concentrated sludge is recycled at low flow rates via an eccentric rotor pump to prevent floc break-up; as discussed earlier, recirculated sludge multiplies contact surfaces and accelerates floc agglomeration phenomena. Flocculation is optimum in the Densadeg when the floc takes up approximately 10% of the space in the mechanical flocculator.
