Dual media Filter
Dual media filter comprises off sand as filtering media and anthracite as polishing media. It is internally equipped with inlet distributor and a bottom collecting system. Externally, it is fitted with isolation valves and frontal pipe work. Sand removes the suspended particles while anthracite is used for removing the odor and colour to make the water good for a number of applications. Gravels and Pebbles are used to provide support to both the media. Once the solids like suspended solids are accumulated, the filter needs to be backwashed. Prior to the backwash, air scouring is also to be done for loosening of dirt and suspended solids. Limit for the backwash in these filers is governed by differential pressure across the filter
