Advantages Of Industrial-grade Diatomite
1.High-Precision Adsorption & Separation：Multi-level pore structure (0.1-50 μm) and high porosity (≥85%) precisely target impurities in industrial feed liquids.Suspended solids retention rate > 98%, heavy metal ion (e.g., Pb²⁺, Cr³⁺) removal rate ≥ 95%, and oil adsorption capacity up to 0.8 g/g, significantly improving product purity. 2.Extreme Environment Resistance:Withstands strong acids and alkalis (pH 1-14) and high temperatures up to 450°C. Compressive strength > 2 MPa, making it ideal for harsh conditions like petrochemical catalysis and metallurgical smelting.Long-term stability outperforms traditional filter media. 3.Energy & Cost Efficiency:High-permeability design increases filtration efficiency by 30% and reduces filter cake resistance by 40%. Waste residue reduced by 35%, lowering overall energy consumption by 20-30% and extending equipment maintenance cycles. 4.Broad Application Compatibility:Customizable particle sizes (20-400 mesh) for diverse industrial needs, including:Petrochemical catalyst recovery,Paint residue removal,Metallurgical flux purification,Industrial wastewater treatment,Compatible with pressure filtration, centrifugation, and vacuum systems. 5.Sustainable Resource Recycling：Filter residue can be regenerated (e.g., precious metal extraction, building material production).Calcination process produces zero pollution emissions, reducing carbon footprint by 25%.Supports corporate ESG (Environmental, Social, and Governance) goals. 6.Long-Term Economic Benefits：High mechanical strength (wear rate < 0.3%) and anti-clogging properties.Reduces total lifecycle costs by 30% and improves return on investment (ROI). Conclusion Industrial-grade diatomite, with its "precision separation + extreme durability" core advantages, empowers industries to achieve high-efficiency production, resource recycling, and low-carbon transformation, addressing critical challenges in high-pollution and high-energy-consumption sectors.
