Sand Filter Plant

Sand Filter Plant

The Pressure Sand Filter consists of a multiple layer of sand with a variety in size and specific gravity. These Filters are designed to remove turbidity and suspended particles present in the feed water with minimum pressure drop.

Sand filters work by allowing water to cycle through a canister that contains sand. The water flows through the sand with ease, but larger particles are unable to pass through. Once the debris and other particles have been filtered out by the sand, a pump moves the clean water back into the pool. As more debris becomes collected by the filter, the efficiency of the filter will start to increase as well; the debris will actually help to keep smaller particles from passing through the sand. In order to ensure consistency and make sure that most if not all of the debris that might be in your pool water is filtered out, sand of a specific makeup and grain size is used. Sand filters use #20 silica sand with grains that fall within the 45 to 55 millimeter range. Any sand that you buy as “pool sand” or “filter sand” will meet this standard, since it is sold specifically for use in sand pool filters.
