Highly Emulsified Acidic Water Treatment in Refining
Process Flow

Process Advantages
1. The first-stage CDFU achieves purely physical demulsification and separation — stable, reliable, and highly efficient in oil removal. Recovered oil reduces secondary pollution with no oily sludge (hazardous waste) generated, resolving environmental compliance issues while creating economic value.
2. The second-stage CDFU requires only a small amount of PAC, significantly reducing chemical dosage. Float scum volume is reduced by more than one-third, minimizing oily sludge (hazardous waste) generation and lowering secondary treatment costs.
3. Closed, pressurized operation prevents hydrogen sulfide and oil-gas leakage, ensuring a safe and environmentally friendly on-site environment.
4. Single-stage retention time is less than 5 minutes, with a small footprint. Fully automated and easy to operate and maintain, with short construction period and capability for online implementation.
5. Strong shock resistance and stable operation, capable of handling significant influent water quality fluctuations.
