Membrane Filtration Technology:
Membrane is a material with selective separation function. The process of separating, purifying and concentrating different components of feed liquid by selective separation of membrane is called membrane separation.
It differs from traditional filtration in that membranes can separate on a molecular scale, and the process is a physical process that does not require phase changes and additives.
The pore size of the membrane is generally nano-scale. According to the different pore size (or molecular weight cut off), the membrane can be divided into microfiltration membrane, ultrafiltration membrane, nanofiltration membrane and reverse osmosis membrane.
The basic principle of membrane separation:
During the filtration process, the feed liquid is pressurized by the pump, and the feed liquid flows along the surface of the filter membrane at a certain flow rate. The molecules of substances larger than the molecular weight cut-off of the membrane do not flow back to the material tank through the membrane, and the substances or molecules smaller than the molecular weight cut-off of the membrane flow back to the material tank. Through the membrane, a dialysate is formed. Therefore, the membrane system has two outlets, one is the return liquid (concentrate) outlet, and the other is the dialysate outlet.
Application:
Since the membrane separation process is a pure physical process, it has the characteristics of no phase change, energy saving, small size, and can be split, so that the membrane is widely used in fermentation, pharmaceutical, plant extraction, chemical, water treatment process and environmental protection industries.
