What Are The Advantages Of Water Treatment Of Diatomaceous Earth?
Water treatment of diatomaceous earth has emerged as a highly effective solution in water purification, leveraging its unique physical and eco-friendly properties. The material's natural porous structure delivers exceptional adsorption capacity, effectively capturing suspended particles, colloids, and heavy metal ions ranging from 0.5 to 50μm, while rapidly reducing water turbidity and COD levels. Compared to conventional filtration media, its porosity exceeding 80% enhances filtration efficiency by 40%, simultaneously decreasing backwashing frequency to significantly reduce energy consumption and operational costs. Through high-temperature activation and modification processes, the treated diatomaceous earth achieves remarkable chemical stability with zero toxic substance leaching, fully complying with China's GB5749 drinking water hygiene standards. When applied in municipal water supply and industrial wastewater treatment systems, it not only provides deep water purification but also maintains essential mineral balance, ensuring both water safety and ecological compatibility. Its lightweight characteristics enable seamless integration with various equipment including sand filters and membrane separation systems, offering operational flexibility and easy sludge recovery to support resource recycling. With broad applicability, diatomaceous earth performs reliably in challenging scenarios such as highly polluted wastewater and swimming pool circulation systems, demonstrating excellent resistance to acids, alkalis, and high-temperature environments while maintaining long-term stability. By combining superior contaminant removal, environmental safety, and multi-scenario adaptability, diatomaceous earth continues to provide dependable support for water purification projects, effectively contributing to green and sustainable development objectives.
