Separation, as an important production link in the chemical industry, can have many processes and methods. Based on the different physical and chemical properties of the separated objects, there can be many methods such as gel chromatography, ion exchange, crystallization, distillation, centrifugation, extraction, adsorption, etc. The membrane separation technology represented by polymer membranes, as a new and efficient fluid separation, purification, and concentration technology, has been widely applied due to its advantages of mostly no phase changes in the operating process, continuous operation at room temperature, simple and easy amplification, high efficiency, energy conservation, and low pollution.

Equipment Process

The membrane separation process uses selective permeation of the membrane as the separation medium. With the help of external energy or some driving force (such as pressure difference, concentration difference, potential difference, etc.) on both sides of the membrane, the raw material side components selectively penetrate the membrane, achieving the purpose of separation, concentration, or purification. Membrane separation methods can be divided into gas (steam) separation and liquid separation according to their separation objects; According to their uses, they can be further divided into reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), microfiltration (MF), dialysis (D), electrodialysis (ED), gas separation (GS), pervaporation (P, ZAP), emulsion membrane ELM, and separation processes combined with other processes - membrane distillation and membrane extraction.
