What Are The Advantages Of Calcined Diatomite Filter Aid?
The Calcined Diatomite filter aid enhances natural diatomite properties through high-temperature calcination, establishing itself as an essential material for precision industrial filtration. Its defining characteristic is an ultra-high porosity (85%+), enabling precise retention of 0.1-30μm suspended particles, colloids, and microorganisms - delivering 60% greater filtration efficiency than standard diatomite. This makes it particularly suitable for demanding applications like injectable drug purification and chemical catalyst recovery. Key Benefits:Exceptional Purity Performance.Pharmaceutical-grade certified with zero leachables. Chemically inert, resistant to strong acids/alkalis.Guarantees 99.9%+ filtrate purity.Maintains stability in high-temperature/high-viscosity media.Operational Excellence. Low-density/high-permeability design.30% reduction in system resistance.25%+ energy savings. 40% extended filter media lifespan.Compatible with plate-and-frame and rotary vacuum filters. Sustainable Advantages.Loose filter cake structure for easy removal.35% reduction in solid waste. Supports recycling and reuse.Fully biodegradable and renewable.Industrial Applications: Pharmaceutical sterile filtration. Petrochemical catalyst recovery. Biopharmaceutical processing.
