Our FRP Sand Filter is a Fiber Reinforced Polymer Sand Filter that is a type of water treatment system. This system is used to remove suspended particles as well as impurities from water. The filter is made of a reinforced fiberglass shell and contains a bed of sand as the filter media. Water flows through the sand bed, & the impurities are trapped in the sand particles. TheFRP Sand Filters are commonly used in swimming pools, industrial applications, and water treatment plants.
