Membrane Filter:
The quality of the membrane material is the basic prerequisite for the application of membrane filtration technology. A good membrane material needs to have a certain high permeability and mechanical stability. Filtration membranes are mainly divided into reverse osmosis membranes, microfiltration membranes, nanofiltration membranes and ultrafiltration membranes according to different pore sizes. The separation mechanism is mostly sieve separation, charge effect and diffusion effect. Membrane filtration mainly intercepts some suspended substances larger than the pore size through the uniform voids on the membrane, and then uses the pressure difference as the driving force to achieve concentration and separation.
Advantages of membrane filtration technology:
1. The energy consumption is low in the process of technology and system application, and no phase change occurs under normal circumstances.
2. The filtration effect is good, multiple substances can be separated, and the efficiency is high.
3. Wide filtering range.
4. The equipment is small in size, which can save floor space.
5. Simple operation, convenient maintenance and repair. The reliability of the application of this technology is also high.
6. It has certain chemical stability and can effectively resist the corrosion of alkali, acid and other substances.
