SCHEMATIC DIAGRAM OF PRIMARY TREATMENT
The first stages of waste water ( sewage ) treatment are commonly physical and aimed to remove larger suspended solids from waste water, primarily using gravity to allow...
Clariflocculator in Waste Water Treatments
In large waste water treatment plants, the flocculator and the clarifier are combined together to achieve economy in construction. The combined unit of flocculator...
The sludge which is found in the bottom of a sedimentation tank in water treatment plant is primarily composed of water. The solids in the sludge are mainly flocs, excess coagulant, such as alum. Alum sludge...
Sedimentation basins have 4 zones
1. The Inlet zone,
2. The Settling zone,
3. The Sludge zone, and
4. The Outlet zone.
Each zone should provide a smooth transition between the zone before and the zone...

Purpose Of Sedimentation
Sedimentation is a unit operation to settle out the suspended particles and flocs in water. Sedimentation water treatment is achieved by lowering the velocity of the water below...
Water Treatment Coagulants
Coagulant water treatment chemicals come in two main types –
