Pressure Sand Filter
Pressure Sand Filter is used for removal of suspended solids & turbidity from Water & Wastewater. Our unique design of Pressure Sand filter ensures the maximum utilization of the surface area, lesser pressure drop across the filter bed and effective removal of the impurities.
Sand filtration is frequently used and very robust method to remove suspended solids from water. The filtration medium consists of a multiple layer of sand with a variety in size and specific gravity. Sand filters can be supplied in different sizes and materials both hand operated or fully automatically.
Working Principle
Raw water is passed through the pressure sand filter, the filter media (Fine quartz sand) is supported on gravel & pebbles bed of progressively larger sizes. During the filtration cycle the filter bed retains the dirt and suspended particles from the water and accumulates within the filter bed. Clear water can be collected from the outlet of filter.
Raw water pump is used for generating necessary operating pressure in the pressure sand filter. Raw water is passed through CHEMTRONICS Multigrade Sand Filter at a pressure of 3.5 kg / cm2 to reduce the suspended solids present in the raw water.
The filter will effectively remove up to 30 – 50 micron of the suspended solids to less then 5 ppm. The filter will have to be washed with raw water for 20 to 30 minutes daily. To filter the partials below 30 – 50 micron cartridge filter is used.
Applications for sand filtration :
- Preparation of cooling water
- Treatment of waste water
- Production of drinking water
- Filtration in swimming pools
- Pre filtration for membrane systems
- Filtration of gray or surface water
- Swimming pool water
