The Remarkable Role of Ozone Catalysts in Wastewater Treatment

Ozone catalysts, as an efficient and environmentally friendly water treatment technology, have been widely applied in the field of wastewater treatment in recent years. Among them, the ozone catalysts developed by SINOKLE have become leaders in the industry due to their unique characteristics and significant effects.

The primary role of ozone catalysts is to promote chemical reactions between ozone and other substances, thereby enhancing treatment efficiency and effectiveness. SINOKLE's ozone catalysts utilize advanced technologies such as multiple active metal oxides and high-porosity microporous molding techniques, featuring high efficiency, reusability, and excellent stability. This catalyst can effectively reduce the reaction activation energy, achieving deep oxidation and maximizing the removal of organic pollutants.

During the wastewater treatment process, ozone catalysts accelerate the decomposition of ozone, increasing the contact time between ozone and wastewater and improving the utilization rate of ozone. Simultaneously, the catalyst can adsorb some organics and directly undergo redox reactions with ozone. The titanium oxide metal and hydroxyl radicals produced can directly oxidize organics, thereby effectively removing pollutants. SINOKLE's ozone catalysts also possess the following technical advantages:

• Improved Ozone Utilization Rate: The presence of the catalyst can significantly increase the utilization rate of ozone, reduce treatment costs, and enhance reaction rates.
• Reduced Energy Consumption: Due to the increased reaction rate, the required ozone and energy consumption can be lowered.
• Enhanced Stability: Heterogeneous catalysts typically exhibit good stability and a long service life, reducing replacement frequency and maintenance costs.
• Strong Adaptability: The ozone treatment system can be adjusted according to different water qualities and treatment requirements, demonstrating excellent adaptability.

Furthermore, SINOKLE's ozone catalysts have demonstrated remarkable effects in practical applications. For example, when treating oily wastewater, Colira used carbon-based ozone catalysts to conduct deep treatment on oily wastewater from a petrochemical plant in Xinjiang. With an ozone dosage of 100 ppm, the COD (chemical oxygen demand) of the raw water was 180 mg/L, while the COD of the effluent was only 23 mg/L, with a COD removal rate exceeding 90%. The influent oil content was 35 ppm, and the effluent oil content was 2.3 ppm. Additionally, the phenol content of the wastewater was reduced from 0.1 mg/L to 0.005 mg/L, and the cyanide content was reduced from 0.19 mg/L to 0.048 mg/L, demonstrating extremely significant treatment effects.

In terms of landfill leachate treatment, SINOKLE's patented CDOF (Cyclonic Dissolved Ozone Flotation Unit) technology fills 80% of the unit with KHC-PC1001 catalysts. Through the ozone catalytic oxidation process, difficult-to-degrade macromolecular organics in landfill leachate are oxidized into easily degradable small molecular organics or even mineralized into CO₂ and H₂O. This technology has achieved remarkable results in an aged landfill leachate treatment project in a landfill site in Zhejiang, with a COD removal rate exceeding 80%, an ozone dosage ratio of only around 1.2, and significant improvements in water quality indicators.

In summary, SINOKLE's ozone catalysts play a crucial role in the field of wastewater treatment due to their technical advantages, high efficiency, and wide range of application cases.
