The water is passed through a Side stream filter to reduce the suspended solids present in the cooling water. This filter is provided to keep a check on the suspended solids. The suspended particles in the cooling water get entrapped in the filter media. The filter will have to be washed with effluent water for 10 to 15 min. daily.
The Filtration Plant has a multiple layers of sand media with different sizes. In this raw water flows down through the filter bed. The media has special surface properties due to which the small colloidal particles get attached to the surface.
There is flow reduction once the pressure drop across the filter is excessive. The filter is now taken out of service and cleaning of the filter is affected by flow reversal.
To assist in cleaning the bed, the backwash operation is often preceded by air agitation through the under-drain system.
The process of air scouring agitates the sand with a scrubbing action, which loosen the intercepted particles.
