Oil Water Separation

With the rapid development of modern industry, the discharge of industrial oily sewage has increased sharply, and the frequent occurrence of leakage accidents during crude oil exploitation and transportation has caused serious damage to the ecological environment. As we all know, oilfield produced water, steel mill cold-rolled emulsion wastewater, and catering oily wastewater contain a large number of refractory organic species. If directly discharged, it will seriously damage the ecological environment such as water resources and soil, and affect human health. Therefore, the technology for oil-water separation has become a research hotspot.

Our group uses wire mesh as the support, and adopts chemical oxidation, etching, hydrothermal method, electrochemical deposition, heat treatment and other methods to obtain super-hydrophilic/underwater super-oleophobic “water-removing” screen film. , has a higher oil-water separation efficiency.
