Nanjing Bidun Environmental Protection
Advanced solution for high-precision treatment of oily wastewater in petroleum refining enterprises
Precision purification technology
The quantity of oily sewage produced in oil refining enterprises is very large. Normally, enterprises adopt the traditional three-stage process: deoiling, air flotation, biochemical treatment and then discharge. However, with the expansion of refinery scale and decline of former handling capacity, the total treatment capacity cannot keep up with demand.
The performance of each process section often fails to satisfy the requirements for the subsequent process sections, especially when the oil content of incoming water to biochemical treatment exceeds 10ppm. This results in the total index of outgoing water remaining in a disqualified state, creating significant environmental compliance pressure for enterprises.
Bidun's oily sewage treatment process utilizes a new type precision treatment oil-removal device based on patented interception oil-removal technology. When air flotation effluent passes through Bidun's oil-removal device, SS, COD and oil content are significantly reduced, with oil content consistently maintained under 10ppm.
The Precision Purification of Industrial Oil Sewage delivers exceptional performance in treating challenging refinery wastewater with high efficiency and reliability.
