Core Element and Structure Feature of 0.45 Disc Vacuum Microfiltration Membrane
Microfiltration membrane is non-toxic and hygienic and mainly made of refined nitrocellulose, microfiltration membrane manufacturers added with the appropriate amount of cellulose acetate, acetone, n-butanol, ethanol, etc. Vacuum microfiltration membrane is a porous membrane filter material with relatively uniform pore size distribution Penetrating micropores with an absolute pore diameter of 80‰. Vacuum membrane filter is divided into the hydrophobic membrane and hydrophilic membrane.
0.45 disc membrane filters are widely used in bio-separation, and mainly used for rough molecule separation which are differences in size. To increase the selectivity for the target molecule by several orders of magnitude, the hydrophobic and hydrophilic membrane will couple with affinity, ion, exchange, hydrophobic interaction, or reversed-phase ligands. Different membrane materials such as polyamide, regenerated cellulose, polystyrene, have been used for different purposes.
The advantages of vacuum microfiltration membrane are flexible. Hydrophobic and hydrophilic membrane can be used in separating, concentrating, and purifying a huge variety of materials in a wide range of different industries. You can find that the processes of microfiltration and ultrafiltration which are capable of fractionating particle species according to size, can operate like “sieves” which high efficiency.
There are no phase changes involved in the process of membrane filtering, whith both feed and product streams remaining in their original liquid form from the beginning till the end. The processes can be active pretty well at low temperatures too.
Hawach microfiltration membrane is always made in a uniform and highly precise manner, helping you make the process relatively simple to scale up and lower your energy requirements at the same time.
Vacuum membrane filter is mainly used for the filtration of water-based solutions, so it is also called water-based membrane. Microfiltration membrane is simple and fast to use and is widely used in scientific research, food inspection, chemical engineering, nanotechnology, energy, and environmental protection.
Core element of vacuum microfiltration membrane
The core element of the vacuum membrane filter is the membrane, which is a membrane filled with more tiny pores prepared on a microporous supporting layer (support). There are many materials for making microfiltration membranes, including organic membranes and inorganic membranes.
Structure feature of 0.45 disc membrane filters
As a filter element, the structural feature of the vacuum membrane filter is that the filter layer is very thin, so its filtration mechanism is mainly the screening effect, and the adsorption effect is very small. Therefore, the filtration accuracy of 0.45 disc membrane filters is high, the particle size control is relatively stable, and the backwashing is easy to restore performance.
However, if the water contains oil, it is easy to block and it is not easy to backwash. Many researchers at home and abroad have hoped to treat produced water with ceramic membranes based on the hydrophilic nature of ceramic materials, but after research, it is generally believed that the problem of membrane fouling is still difficult to solve. Membrane fouling is a very complicated problem, but one thing is certain, that is, a large amount of organic matter in the contaminants is certain. However, the vacuum microfiltration membrane itself is generally concerned with less consideration of the supporting layer.
