A sand-anthracite filter or dual media filter/multi-media filter is primarily used for the removal of turbidity and suspended solids as low as 10-20 microns. Dual media filters provide very efficient particle removal under the conditions of high filtration rate. Inside a sand-anthracite filter is a layered bed of filter media. The bed is graded from bottom to top as follows: Having the filter media graded this way enables the sand
anthracite Filter to run for longer times before a backwash is necessary. A sand
anthracite filter or multi-media filter consists of 2 main parts: Internally, the dual media filter is fitted with an inlet
distributor and a bottom Colleting system. Externally, the system is fitted with
frontal pipe work and isolation valves. Sand is used to remove the suspended
particles and anthracite is used to remove the odor and color etc. to make the
water fit for different applications. Gravels and pebbles are provided to
support to both the media. Periodically, the sand-anthracite filter will
backwash, which changes the water flow through the sand-anthracite filter. |
