>More and more oily wastewater has been generated from the development of oilfields, especially for those using water injection technology. It usually contains a large amount of abundant of emulsified oil, soluble organic matter, solid particles, inorganic ions, bacteria and the like.
>Ceramic nanofiltration membrane has excellent thermal stability, chemical stability, solvent resistance and high separation precision. It can effectively retain oil and the effluent quality is stable.
