First, types of uf membrane module

1. The organic membrane is mainly made of polymer materials, such as cellulose ester, aromatic acrylic resin, polyethersulfone, polyvinylidene fluoride, etc. According to the different appearance of membrane, it can be divided into flat membrane, tubular membrane, capillary membrane, hollow fiber membrane, etc.

2. Among inorganic membranes, ceramic ultrafiltration membranes is widely used. The microfiltration has a long service life and is corrosion-resistant, but the water output has an earthy smell, which affects the taste. At the same time, the microfiltration is easy to block and difficult to clean. Hollow fiber uf membrane is widely used in the field of household water purification due to its advantages of high packing density, reasonable total membrane area, high pure water flux, convenient use, and convenient cleaning.

3. It is not difficult to see that the hollow fiber uf membrane can be either an organic membrane or an inorganic membrane. The hollow fiber uf membrane module is designed like a fiber with the effect of self-supporting points. The outer diameter of the hollow chemical fiber is 0.5-2.0mm, and the inner diameter: 0.3-1.4mm. The raw water is pressurized and fluidized on both sides or the inner wall of the hollow fiber to form external pressure and internal pressure. Ultrafiltration membrane equipment is a dynamic filtration process. The intercepted chemical substances can be removed with the concentration, without clogging the membrane surface, and can run continuously for a long time.

Second, the application of uf membrane module in various fields

1. Application in dairy industry production.
It has been used to concentrate skim milk overseas, and can be made into skim milk with a protein content of up to 50%-80%.
2. Application in the field of household water purifiers.
Household ultrafiltration water purifiers are the main household water purifiers on the market. Its key component is the uf membrane module, which can remove biological macromolecules, colloidal solutions, proteins, particles, etc. in saturated solutions. It has the characteristics of low working pressure, high water production rate and beneficial to practical operation.
3. Application of sewage treatment.
At present, it has been used in the treatment scheme of spraying sewage in vehicle processing and manufacturing, metal laser cutting sewage and food chemical wastewater, as well as the recycling of chemical substances.
4. The application of brewing raw water.

It is used in small beer sprinkler production lines, and ultrafiltration membrane is used to deeply purify the brewing raw water, which can effectively reduce the concentration of various pollutants in the water and remove the secondary pollution caused by the pipe network, fully meeting the requirements of high-quality raw water required by the brewing process.
