CDOF Technology: Redefining the Efficient and Environmentally Friendly Wastewater Treatment Revolution

In industrial wastewater treatment, conventional processes often suffer from low efficiency, high cost and secondary pollution. Independently developed by SINOKLE, the CDOF(Cyclonic Dissolved Ozone Flotation Unit) integrated ozone catalytic oxidation and flotation technology is centred on 'high efficiency, environmental friendliness and intelligence' and provides breakthrough solutions for petrochemicals, landfill leachate, pharmaceuticals, metallurgy and other industries, becoming a benchmark of advanced technology in wastewater treatment.

Technical Breakthrough: Three Core Advantages Reshape the Industry Landscape

1. 'Multi-catalytic oxidation + flotation' integration: treatment efficiency increased 10 times
   CDOF technology innovatively integrates multiple ozone catalytic oxidation, cyclonic separation and dissolved gas flotation to form a closed loop of 'oxidation - demulsification - separation'. Through a patented catalyst, ozone is converted into highly active hydroxyl radicals (OH), raising oxidation efficiency 2-5 times over conventional methods, shortening reaction time from 60 minutes to 5-10 minutes, and reducing equipment footprint to 1/10 of conventional processes. For example, in a landfill project in Zhejiang, the CDOF technology achieved COD removal above 80%, reducing effluent COD from 1,500 mg/L to below 200 mg/L while raising B/C (biodegradability) from 0.22 to 0.37, laying the foundation for subsequent biological treatment.

2. Low-cost operation: energy consumption reduced by 75%
   Conventional ozone oxidation suffers from low ozone utilisation and high energy consumption, whereas the CDOF technology, through catalyst optimisation and cyclonic flotation synergy, cuts ozone consumption to 1/8-1/4 of conventional processes. In a petrochemical wastewater project in Xinjiang, at an ozone dosage of 100 ppm, COD removal exceeded 90%, oil content fell from 35 ppm to 2.3 ppm, and oily sludge (hazardous waste) generation dropped by more than 90%, saving over RMB 1 million per year in hazardous waste disposal costs.

3. Fully automated closed operation: safe, environmentally friendly and pollution-free
   CDOF equipment adopts a fully closed pressurised design with an integrated intelligent control system, achieving unattended fully automatic operation. The ozone leakage rate is virtually zero, avoiding secondary pollution risk; meanwhile, micro-bubble flotation reduces flocculant dosage and chemical residues. In a landfill leachate treatment project in Shenzhen, the CDOF technology enabled effluent quality to stably meet China's Class I-A national standard and improved system operating stability by 300%, thoroughly solving the traditional susceptibility to water-quality fluctuations.

Application Scenarios: Full Coverage from Industrial Wastewater to Municipal Sewage

CDOF technology has been successfully applied to oil-produced water, landfill leachate, pharmaceutical wastewater, dye wastewater and other difficult scenarios. For example, in diphenylguanidine wastewater treatment, the technology broke through the bottleneck of poor results and high cost in conventional processes, saving the enterprise more than 50% in operating costs; in oily wastewater treatment at heavy-oil power plants, its compact design and high treatment capacity make it a powerful tool for green power generation.

Conclusion
SINOKLE CDOF technology, centred on an 'innovative catalytic system + intelligent flotation process', redefines the standards of efficiency and environmental protection in wastewater treatment. Whether in reducing enterprise operating costs or supporting the realisation of the 'dual carbon' goals, the SINOKLE CDOF demonstrates strong technical vitality. Choosing CDOF is to choose the new paradigm for future wastewater treatment!
