Sludge theory
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.

WebbDepending on the concentration of solids and the tendency of particles to interact the following four types of settling may occur: 1. Type 1 – Discrete settling. 2. Type 2 – Flocculent settling. 3. Type 3 – Hindered or zone settling. 4. Type 4 – Compression settling.
WebbActivated sludge treatment process (ASTP) is the most common classification of biological treatment process used in the IW treatment.
