CDOF: Innovative Breakthrough in High Polymer Wastewater Treatment Technology
High polymer wastewater is one of the significant environmental challenges faced by the petrochemical industry. This type of wastewater contains large amounts of polymers and surfactants, exhibiting characteristics such as high viscosity, severe emulsification, and difficulty in degradation. With its self-developed CDOF (Cyclonic Dissolved Ozone Flotation) technology, the Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) has provided an innovative solution for the treatment of high polymer wastewater.
Technical Principles and Innovative Advantages
The CDOF technology creatively combines multi-stage catalytic ozonation, cyclonic technology, and dissolved air flotation into an integrated, efficient treatment system. This technology uses a specially patented reactor structure to achieve multi-stage, multi-dimensional catalytic oxidation reactions, including pressurized catalysis, homogeneous and heterogeneous catalytic oxidation, and hydraulic cavitation catalysis, among other processes.
Compared to traditional methods, the CDOF technology has significant advantages:
- Significantly improved reaction efficiency: The residence time is reduced from the traditional 90 minutes to less than 15 minutes.
- Extremely high ozone utilization rate: Achieves over 99.98%, with the dosage being only 1/5 to 1/2 of the traditional method.
- Significant reduction in operating costs: Costs are reduced to 1/3 to 1/2 of traditional methods.
- Small footprint: Modular design, occupying only 1/5 of the space required by traditional methods.
Core Technological Innovations
The heterogeneous ozone catalyst is the core of the technology. The SINOKLE uses various transition metal oxides and precious metals as catalytic components, and through a special micropore molding technology, creates a high-surface-area carrier with a surface area exceeding 250 m²/g. The catalyst is modified using atomic deposition technology, which gives it super hydrophilicity, making it resistant to contamination, scaling, and clogging, allowing for long-term stable operation.
Heterogeneous Ozone Catalyst
The multi-stage catalytic oxidation system ensures stable and reliable treatment performance. The system integrates multiple technologies, including homogeneous and heterogeneous catalytic oxidation, hydraulic cavitation catalysis, and micro-pressure catalytic oxidation, achieving 2-5 times higher oxidation efficiency compared to traditional ozone catalytic oxidation. The specialized catalyst has strong activity, high strength, and a wide pH adaptability range, maintaining excellent performance under both acidic and alkaline conditions.
Process Features and Operational Assurance
The CDOF unit uses a fully automated control system, precisely controlling parameters such as ozone dosage, reaction liquid level, and pressure through DCS/PLC. The unique catalyst backwashing, activation, and regeneration process ensures the long-term stability of the catalyst's performance, eliminating the need for regular dosing and significantly reducing operation and maintenance costs.
The unit operates in a fully enclosed, pressurized mode, preventing ozone leakage and ensuring safety and environmental protection. The system is highly resistant to shocks and can withstand significant water quality fluctuations, ensuring stable operation under complex water conditions in high polymer wastewater.

Applications
In actual engineering applications, the CDOF technology has demonstrated outstanding treatment performance. For high polymer wastewater, this technology effectively destroys the polymer molecular structure, achieving deep oxidative degradation of organic matter. The treated effluent's COD, suspended solids, and other indicators remain stable and meet standards, while also providing excellent decolorization and odor removal effects.
The CDOF technology from the SINOKLE provides an efficient, economical, and environmentally friendly solution for high polymer wastewater treatment. Its innovative technical approach and reliable engineering practices offer strong support for the green development of the petrochemical industry. As environmental regulations continue to tighten, this technology will play an important role in more complex wastewater treatment scenarios.
