CDFU, the full name in English is Cyclonic Dissolved Gas Flotation Unit. It is a new generation of green and efficient compact vertical tank air flotation equipment developed by SINOKLE. This equipment integrates patented technologies such as cyclone centrifugal separation technology, ultra-fine bubble generation technology, and dissolved air flotation technology. Through the organic combination of multiple technologies, it can achieve efficient and rapid separation of dirty oil, emulsified oil, suspended solids, etc. in sewage.

The commissioning work was carried out by the first refinery workshop of UPC. In the early stage, the workshop divided the responsibilities of the teams, and the leaders took the lead in confirming step by step. After three checks and four determinations, sufficient preliminary preparations were made, and good test conditions were met.

On January 9, test runs began. On January 10, all internal processes were cleared, and all instruments inside the skid were debugged normally. On January 11, the entire skid installation was completed. On January 13, the test run was successful.

After the device is put into use, it is expected to receive 50-60 tons/hour of second-normal, third-normal, and pre-treatment electric desalination water. This set of facilities can achieve oil-water separation of highly oily sewage, reduce the generation of sludge, and reduce operating costs. It has good environmental benefits and economic benefits.


CDFU cyclone dissolved air flotation equipment has outstanding advantages such as compact structure, small footprint, low operating cost, high removal rate of emulsified oil and fine suspended solids, and does not require the use of chemicals. It is especially suitable for oil fields, refineries or offshore The platform's ability to treat highly difficult sewage containing emulsified oil and fine suspended particles has been successfully used in more than 30 difficult sewage treatment projects at home and abroad and achieved stable operation.
