Membrane Separate

Membrane separation is a new separation technology that emerged in the early 20th century and rose rapidly after the 1960s. Membrane separation technology has the functions of separation, concentration, purification and refining, high efficiency, energy saving, environmental protection, molecular filtration and simple filtration process, easy to control, etc. Therefore, it has been widely used in food, medicine, biology, Environmental protection, chemical, metallurgy, energy, petroleum, water treatment, electronics, bionics and other fields have produced enormous economic and social benefits, and have become one of the most important means in today’s separation science.

Membrane separation is an emerging interdisciplinary high-tech. The material of the membrane involves inorganic chemistry and polymer chemistry; the preparation of the membrane, the characteristics of the separation process, the transfer properties and the transfer mechanism belong to the field of physical chemistry and mathematics; the fluid mechanics, heat transfer, mass transfer, chemical power involved in the membrane separation process The design of the process and process is mainly in the field of chemical engineering research. From the field of membrane separation, it also involves biology, medicine and disciplines related to food, petrochemical, environmental protection and other industries.
The membrane separation process has become an important process for the separation and purification of industrial gas separation, aqueous separation, chemical and biochemical products. Widely used in food, beverage processing, industrial wastewater treatment, large-scale air separation, hydrometallurgical technology, gas and liquid fuel production, and petrochemical production.

Based on relevant practical projects, the research team applied membrane separation technology to the field of dye/divalent salt separation and achieved good practical results.
