Compared with the above methods, membrane separation technology can adjust the pore size as needed to achieve precise separation. Moreover, membrane separation method does not require the introduction of a third phase, has mild operating conditions, and high separation efficiency, making it an effective way to achieve oil-water separation.

Inorganic ceramic membrane is a precision ceramic filtration material with a porous structure, which is sintered at 1360 ℃ using alumina, titanium oxide, zirconia, and other materials. The porous support layer, transition layer, and microporous membrane layer are asymmetrically distributed, and the filtration accuracy includes microfiltration, ultrafiltration, and nanofiltration.

MBR, also known as membrane bioreactor, is a new water treatment technology combining activated sludge process and membrane separation technology. At present, MBR membrane is mainly divided into four types: hollow fiber membrane, flat ceramic membrane, ceramic membrane and tubular membrane.

As a new, efficient and precise separation technology, Ceramic membrane separation technology has been given more application space in the field of water treatment. With the increasing severity of water pollution, Ceramic membrane separation technology will have a broader development prospect.

Nowadays, membrane technology has developed rapidly and has been applied in all walks of life. Today we will introduce ultrafiltration membrane in membrane technology.
