Calcined Kieselguhr

Calcined Kieselguhr

Calcined kieselguhr is produced through high-temperature treatment of natural diatomite, achieving a porosity exceeding 85% and demonstrating exceptional adsorption capacity and chemical stability. This advanced filtration material is widely applied in chemical, environmental, and food industries for high-efficiency separation processes.

Key Characteristics:Precision Filtration - Microporous structure effectively captures 0.2-30μm impurities, significantly enhancing liquid purity.

Chemical Resistance - Withstands acid/alkali corrosion with no leaching risks, meeting industrial safety standards.Enhanced Performance - Low density and high permeability improve flow rates by 50+% compared to conventional media.Equipment Compatibility - Optimized for pressure filters, rotary vacuum drums, and other industrial systems.

Operational Advantages:Easy filter cake removal and recyclability,Reduces solid waste generation by 30%,Combines filtration efficiency with environmental sustainability,Ideal for applications requiring both precision and process reliability.
