Sedimentation Flow Diagram

Sedimantation or clarifier is the process of removing contaminants from water by settling to the bottom of conical shape tanks. These contaminants can be suspended solids, settleable solids, chemical sludge, biological sludge or microrganism. The purpose of this type of seperation is to clarify turbid water in two phases of solid and liquid.

Sedimentation system required coagulant and flocculant aid such as alum, PAC and polymer to help small size particles or colloid settling in such a contact time.

This application is most needed in raw water pretreatment. Sources of raw water can be rivers, canals, reservoirs, well water or wastewater.
