CDOF(Cyclonic Dissolved Ozone Flotation Unit)

Product Detail

1. Technology Introduction

 

The Cyclonic Dissolved Ozone Flotation Unit (CDOF) is a patented technology independently developed by SINOKLE. CDOF integrates multiple advanced technologies into a single unit, including catalytic ozone oxidation, cyclonic technology, dissolved gas flotation, and more. It excels in the efficient oxidation and comprehensive removal of refractory contaminants from various wastewater types, achieving an internationally advanced level of performance.

Applications:

Petroleum refining, power generation, metallurgy, pharmaceuticals, printing and dyeing, municipal wastewater, landfill leachate, river sewage treatment, etc.

 

2. Technical Principle

 

Under the action of SINOKLE’s proprietary high-efficiency heterogeneous catalyst, ozone is efficiently converted into highly reactive hydroxyl radicals (·OH). These radicals break down refractory organic pollutants, converting them into smaller, more easily treatable molecules that ultimately degrade into CO₂ and H₂O.

 

 

 

3. Highly Efficient Heterogeneous Catalyst

 

The ozone catalyst used in the CDOF system is a patented product developed by SINOKLE. It integrates multiple active metal oxides, including precious metals, into a unified system. Using advanced high-porosity microporous forming technology combined with hydrophilic modifications for anti-fouling and anti-clogging, the catalyst ensures exceptionally stable and efficient performance.

 

 



 

4. Technical Advantages

 

· Innovative Integrated Technology:

Combines ozone multi-catalytic oxidation, cyclonic dissolved gas flotation, and coagulation to efficiently remove COD, suspended solids, colloids, bacteria, viruses, and more.

 

· Patented Reactor Structure:

Features a special reactor design with extremely fast reaction times (residence time <15 minutes, compared to 90 minutes in traditional systems). The process is sealed and pressurized, preventing ozone leakage and ensuring safety and environmental protection.

 

· High Ozone Utilization Efficiency:

Ozone utilization exceeds 99.98%, with an ozone dosage ratio of 0.5 to 1.2 (compared to 2 to 4 in traditional systems), reducing operating costs by 1/3 to 1/2 compared to traditional methods.

 

· Automatic Control Technology:

Fully automated control via DCS/PLC technology allows precise regulation of ozone dosage, reaction liquid level, pressure, and exhaust gas concentration. The system can optimize automatically based on water quality, further reducing operational costs.

 

· Advanced Catalyst:

Utilizes a specialized catalyst with high activity, strength, and a large specific surface area. It is highly resistant to pollution and can operate across a wide pH range (acidic to alkaline), ensuring long-term effectiveness.

 

5. Wastewater Treatment Plant Technologies

 

After biochemical degradation, the remaining organic pollutants in the water are often soluble and refractory. Our CDFU+HIBR+CDOF technology effectively oxidizes these organic pollutants, reducing the COD index and achieving decolorization. It also provides sterilization and disinfection without causing secondary pollution. The treated effluent meets the Chinese Grade A standard of the Pollutant Discharge Standard for Urban Sewage Treatment Plants (GB18918-2002).
