Webb25 dec. 2024 · The technology of low-loaded activated sludge is used. The excess sludge formed in biological treatment is collected in a gravity thickener, where the hydration is reduced to approximately 98.5–98%. Then, the sludge is mechanically thickened in a decanter centrifuge to a dry matter content of approximately 5%. WebbA thickener/clarifier apparatus comprising: a settling tank (20) providing for the settling of particulate material residing within liquid contained within said settling tank (20) and facilitating the formation of a clarified liquid phase in an upper region of said settling tank (20); a feedwell body (22) disposed inside said settling tank (20); at least one open …
WebbSludge Thickeners The HEI Sludge Thickener is an efficient method to gravity concentrate and decant waste sludge. Liquid sludge pumped from a clarifier will have a solids content of 0.5% from cone bottom clarifiers to 2%-4% from the rake bottom clarifiers. WebbAfter the sludge has been flocculated in the feed pipe, it enters the gravity zone where most of the liquids and solids are separated. A spreader plate ensures uniform distribution over the working width of the belt. PowerDrain belt thickener units can be equipped with two to four rows of ploughs, which compact, rearrange, and deflect the sludge.
