Fine Quartz Filter Sand are used as topmost layer in filter bed. Quartz sand is a silica, crystalline quartz media which can be used as highly efficient filter media for the reduction of suspended matter. Its fractured edges and irregular surface provides a high surface area and complex flow path for efficient removal of suspended matter throughout the filter bed.
