Sand Filters
Sand Filters
Properties :
- Designed and developed to remove turbidity and suspended particles present in the feed water with minimum pressure drop.
- The Filter consists of a multiple layer of sand with a variety in size and specific gravity.
- In sand filters water enters in the filter and percolates through the filter bed.
- Suspended matter present in the water comes in contact with the media particles.
- Trapped on the top of the bed
- By this phenomenon, clean water comes out through the filtration nozzles and through the filter outlet.
- Periodically cleaning of this filter is done by backwashing
- Water is introduced in the reverse direction of the service flow that is from the outlet nozzle upwards
- Causing suspension of the turbid material in the filter bed & finally flushing out through the backwash valve
- The Filter is then down rinsed & clear water is taken in the system
