Sand Filter

Sand Filters are recommended for places where the input water has traces of sand in it.
You must have observed a sudden gush of sand along with water on opening a tap.
Imagine the harm inflicted on your clothes once they are washed with water containing sand.
Presence of sand also effects the life and performance of other appliances in house like washing machine, geysers and dish washers.
Some people experience irritation while having a bath with such water. Not only this, the post bath feeling is not good at all.
Sand Filter is an ideal solution for the systems with high sediment, silt, sand, and turbidity. The sand filters are specially designed to take care of the range of suspended impurities.


A sand filter is made up of beds of fine sand, gravel and coarse gravel which are placed inside a vessel.
Service Mode – This is the normal working mode of the sand filter.
Water comes from inlet through the Multiport Valve and drops on the sand bed which takes care of all suspended particles.
Clear water flows down and is collected by the Riser tube at the bottom from where the outlet is provided.
Cleaning the Sand Filter – Also known as Backwash
The reverse process is applied. We put the valve on the Back flush Mode.
Now all the water will enter inside the vessel through the Riser tube and will come out from the base of the vessel.
Entire dirt, sand, sediment particles which have been trapped by the sand are discarded through the Drain Pipe.
