WebJan 11, 2024 · Gravity thickening is most effective on primary sludge. In operation, solids are withdrawn from primary treatment (and sometimes secondary treatment) and are pumped to the thickener. The solids buildup in the thickener forms a solids blanket on the bottom. The weight of the blanket compresses the solids on the bottom and squeezes … WebA gravity thickener is used to concentrate 40 GPM of waste activated sludge at a concentration of 0.9% (9,000 mg/L). The underflow sludge is withdrawn at 3 percent and the effluent suspended solids concentration is 1,800 mg/L. Determine the suspended solids removal efficiency (%) and the concentration factor. Adv. Chapter 2: Activated Sludge Web1. Gravity Thickening: This process involves the concentration of thin sludges to more dense sludge in special circular tanks designed for this purpose.
