Membrane Filtration Technology
Membrane filtration technology is, actually a kind of membrane separation technology, in which the driving force relies on the pressure. And membrane filter technology includes MF, UF, NF, and RO. When the solution flows over the membrane, under certain pressure, only water or some small molecule is allowed to get through the numerous micropores distributing over the membrane and turned into permeate.
Other matters whose volume is greater than the diameter of membrane micropores would be stopped and turned into a concentrated solution. According to this principle, the membrane filter realizes solution separation and concentration. It is a kind of advanced water treatment technology.
The installing of the membrane component
Make sure the system has been cleaned before you install the membrane components. Before you install the reverse osmosis membrane into the system, the O ring and the seal need to be lubricated. You can use a 50% glycerin-water solution. Oil, grease, vaseline, or other petroleum compound are prohibited.
The microfiltration membrane is a kind of precise filtration and can be divided into dead-end and crossflow. The former is usually used in small-scale applications and the filter elements are always one-off. The latter is usually used on an industry huge scale and it requires periodic cleaning and regeneration to recover the filtering performance of the membrane.
Micro-filtration membrane mainly used in the pharmaceutical industry degerming filtration. Besides, it is also widely used in urban sewage disposal and wastewater treatment preprocessing.
Ultrafiltration membrane is a kind of membrane process which is between nanofiltration and microfiltration. It applies to the separation, concentration, and purification of macromolecular substances and small molecular substance.
The early industry ultrafiltration only applied to the treatment of sewage and wastewater. In the latest decades, with the development of ultrafiltration technology, it has been used in the food and drinks processing, medicine industry, clinical medicine, and sewage treatment, etc.
