Sludge application settlement subclass
WebbIntroduction. Sedimentation is the process of allowing particles in suspension in water to settle out of the suspension under the effect of gravity. The particles that settle out from the suspension become sediment, and in water treatment is known as sludge. When a thick layer of sediment continues to settle, this is known as consolidation. WebbIn this type of settling tank, the sludge formed by flocculation constitutes an expanded mass through which the raw water to be treated, having previously been coagulated, percolates upwards in a regular and even …
