Description
Pool Grade Diatomaceous Earth: High-Efficiency Filter Media for Crystal-Clear Pool Water
Pool grade diatomaceous earth is a natural siliceous mineral derived from ancient diatom fossils, formed through millions of years of geological sedimentation. As a professional filter media, its core component is silicon dioxide (≥85%), with trace amounts of alumina and iron oxide, giving it exceptional filtration performance.
Microscopically, it features a honeycomb porous structure with 85%-90% porosity and a specific surface area of 30-65 m²/g, enabling it to trap particles as small as 3-5 microns—10 times more efficient than traditional sand filters. It effectively removes algae, bacteria, amoeba, and fine impurities from pool water, keeping it crystal-clear and healthy. Chemically stable, acid-resistant, non-toxic, and odorless, it maintains stable performance in long-term pool water circulation (pH 6.5-8.5) and is compatible with common pool chemicals.
Hebei Hezhen Industrial Co., Ltd., a professional pool-grade diatomaceous earth manufacturer, produces products with strict quality control: SiO₂ content ≥85%, moisture ≤0.8%, and ignition loss ≤5%. We offer customized mesh sizes (325-1250 mesh) and bulk supply, with products exported to Europe, America, Australia, and Southeast Asia, providing reliable filtration solutions for commercial swimming pools, residential pools, and water parks.
