Feb 24, 2021Primary sludge and surplus sludge are then brought together and enter the sludge treatment section. This sludge typically contains 5 to 10 grams per liter of total dry solids and should normally be thickened to 5 to 8% before being pumped into the digestion tower. This process removes 90 to 95% of the water from the slurry.CHAPTER 5 SLUDGE TREATMENT FACILITIES 5.1 The role of sludge thickening is to thicken the sludge of low concentration generated in STPs, and to make subsequent processes such as sludge digestion and sludge de-watering more effective. Thickened sludge may be of two kinds primary sludge generated in the primary settling tank and excess sludge generated in the secondary settling tank.China Center Drive Mining Thickener Manufacturers, Factory Large Sludge ConcentratorCenter Drive Mining Thickener.

Both are methods of solids concentration and volume reduction. Only the degree of volume reduction is different. Generally thickeners concentrate sludge at lower than 15% concentration, the dewatering units concentrate the sludge to higher than 15% concentration [3].
