2. Technical Principles

Under the action of the highly efficient heterogeneous catalyst developed by our company, ozone is efficiently transformed into hydroxyl (·OH) with strong oxidation, and the ring opening and chain breaking of refractory organic pollutants are realized to form easily treatable small molecular organic matter, and finally CO2 and H2O are generated.






3. Highly Efficient Heterogeneous Catalyst

The ozone catalyst utilized in CODF systems is a patented product independently developed by SINOKLE. This advanced catalyst integrates multiple active metal oxides (including precious metals) into a unified system. Through the application of high-porosity microporous forming technology combined with hydrophilic modification for anti-fouling and anti-clogging capabilities, the catalyst delivers exceptionally stable and efficient performance.








4. Technical advantages

A. Pioneering an integrated technology that integrates ozone multi-catalytic oxidation, cyclonic dissolved gas flotation, and coagulation, efficiently removing COD, suspended solids, colloids, bacteria, viruses, etc.




B. Special patented reactor structure, extremely fast reaction, residence time less than 15 minutes (traditional 90 minutes), operates sealed and pressurized, with no ozone leakage, ensuring safety and environmental protection.




C. Ozone utilization rate exceeds 99.98%, with an ozone dosage ratio of 0.5 to 1.2 (traditional 2 to 4), accounting for 1/5 to 1/2 of traditional methods, and operating costs are 1/3 to 1/2 of traditional methods.




D. Utilizes DCS/PLC fully automatic control technology, precisely controlling ozone dosage, reaction liquid level, pressure, exhaust gas concentration, etc. It can automatically optimize based on water quality, reducing operational costs




E. Employs a specialized catalyst with high activity, strength, and large specific surface area, strong resistance to pollution, and a wide pH adaptability range (acidic, alkaline), ensuring long-term effectiveness.




5. Technologies for Wastewater Treatment Plant

After biochemical degradation treatment, most of the remaining organic pollutants in the water are soluble and refractory organic pollutants. Our CDFU+HIBR+CDOF technology is adopted to efficiently oxidize organic pollutants, reduce COD index and decolorization, and has the function of sterilization and disinfection without secondary pollution. The effluent index meets the Grade A standard of "Pollutant Discharge Standard of Urban Sewage Treatment Plant" (GB18918-2002).
