Swimming Pool Grade Diatomaceous Earth CAS 68855-54-9 for DE Pool Filter Media
Swimming Pool Grade Diatomaceous Earth CAS 68855‑54‑9 is flux‑calcined diatomite specially developed for DE swimming pool filters. Optimized particle‑size distribution forms stable pre‑coat layer on filter grids. It efficiently removes fine dust, organic debris, algae spores and micro suspended contaminants from circulating pool water. High water permeability reduces backwash frequency. Low leachable impurities, safe for recreational pool water, widely used in residential and commercial swimming
Product Overview
Swimming Pool Grade Diatomaceous Earth CAS 68855‑54‑9 for DE Pool Filter MediaOrdinary sand filters are limited in capturing micro contaminants in pool water. This swimming pool grade diatomaceous earth is dedicated consumable for DE pool filter tanks. It builds thin, porous filter bed on filter manifold grids, intercepts tiny impurities that sand filters cannot trap, to achieve crystal‑clear pool water. Suitable for initial filling and regular media replacement for both household and commercial swimming pool filtration equipment.
