The conventional treatment for production of drinking water from surface water generally consists of coagulation, flocculation, sedimentation and sand filtration. One of the main disadvantages of the conventional process combining sedimentation and filtration is the rather long residence time.

Not all systems use presedimentation, but presedimentation is often used when raw water turbidity is high or highly variable. Presedimentation basins range in size, depending on the flow, and the water is sometimes pretreated with a coagulant and/or a polymer prior to entering the presedimentation .

Took about five liters of water in a plastic bucket and added half a teaspoon of powdered Alum (that is about 50 mg which works out to 10 mg per liter of water) and stirred well. This bucket of water needs to be kept still for about 6 to 7 hours so that the sediments get coagulated and settles down at the bottom.

Coagulation is always considered along with flocculation and is used to remove particles which cannot be removed by sedimentation or filtration alone. These particles are usually less than 1 μm in size and are termed colloids. They have poor settling characteristics and are responsible for the colour and turbidity of water.

Coagulation stage: Alum and other chemicals are added to the water at this stage. Suspended particles get stuck to the chemicals to form 'floc'. Sedimentation Stage: As particles get stuck they become heavy and sink to the bottom of the chamber. At this stage, most of the particles are stuck to form sediments, sinking to the bottom.
