A sedimentation tank is a structure used to remove suspended solids from water, mainly achieving solid-liquid separation through gravity settling. Sedimentation tanks play an important role in sewage treatment and are widely used in the treatment of industrial water and domestic sewage. ‌

Basic principle of sedimentation tank

The sedimentation tank utilizes natural sedimentation or coagulation sedimentation to remove suspended solids from water. The basic principle is to purify water by causing suspended particles to sink through the action of gravity. The sedimentation effect depends on the flow rate of water and the residence time in the pool. In order to improve the sedimentation effect, technologies such as honeycomb inclined tube opposite flow sedimentation tank, accelerated clarification tank, pulse clarification tank, etc. are often used.
