Sewage Treatment Of Diatomaceous Earth

Sewage Treatment Of Diatomaceous Earth

Sewage treatment of diatomaceous earth is refined from premium diatomite ore through proprietary thermal activation technology, achieving exceptional adsorption capabilities with ≥88% SiO₂ content, ≥80% porosity, 50-70m²/g specific surface area, and precisely calibrated 0.5-15μm pore structure for optimal contaminant targeting. This advanced filtration medium delivers:Heavy metal ion removal efficiency >95% (including Pb²⁺, Cd²⁺)，≥85% COD reduction for organic pollutants，Significant turbidity and BOD reduction，Engineered for harsh environments with acid/alkali resistance (pH 2-12) and biological corrosion resistance, it's ideal for both industrial effluent and municipal wastewater treatment, compatible with press filters, sedimentation tanks and other standard equipment.Operational Advantages:Ultra-low dosage (0.1-0.5% by volume)，40% sludge volume reduction，30% faster dewatering performance

，Environmentally certified non-toxic solution，Sustainable disposal options (solidification landfill or resource recovery)，Combining cost-efficiency with broad system compatibility, Shengtai's diatomaceous earth solution enables reliable compliance with discharge standards while supporting ecological restoration initiatives. The product's unique pore architecture and surface chemistry provide superior contaminant capture across diverse wastewater treatment applications.

What Are The Advantages Of Sewage Treatment Of Diatomaceous Earth？
1.High-Efficiency Pollutant Removal Heavy Metal Adsorption: The porous structure of diatomaceous earth achieves over 98% adsorption efficiency for heavy metal ions through ion exchange and surface complexation, particularly effective for hard-to-degrade organic compounds. 2.Multifunctional Synergistic Treatment Decolorization & Deodorization: Removes >90% of dye wastewater color while adsorbing odor-causing substances like ammonia nitrogen and hydrogen sulfide. Microbial Carrier: The porous surface provides attachment sites for microorganisms, enabling biofilm reactor construction to enhance biochemical treatment efficiency. 3.Eco-Friendly & Sustainable Naturally Non-Toxic: Sourced from fossilized diatoms, free from heavy metals and harmful chemicals, compliant with GB/T 24251-2009 environmental standards. Regenerable & Recyclable: Can be reactivated for repeated use, minimizing waste. 4.Cost-Effective Performance Low-Cost & Easy Operation: Requires no complex equipment—can be directly dosed or integrated with existing processes (e.g., sedimentation tanks, sand filters). Broad Applicability: Suitable for municipal sewage, textile dyeing wastewater, electroplating effluent, papermaking black liquor, and more. Conclusion: With its high adsorption capacity, multifunctional synergy, and eco-economic benefits, diatomaceous earth is an ideal alternative to traditional chemical agents. It demonstrates exceptional advantages in heavy metal remediation and resource recovery, aligning with China’s "Dual Carbon" strategy and holding significant potential for widespread adoption.
