In recent years, with the development of new technologies, the screening function of the pvdf ultrafiltration membrane has also been improved and enhanced to a certain extent, and therefore, its contribution to human society is increasing. Pvdf ultrafiltration membrane is not only widely used in industrial applications, but also very common in the formulation field. The ro membrane filter can be used in most fields involving filtration.

1. The main purpose of pvdf ultrafiltration membrane

The ro uf membrane is to filter water, which has a purification function. The pressure difference between the two sides of the membrane is used as the driving force during the whole process, and the filter membrane is used as the filter material. Under a certain working pressure, when the original liquid passes through the membrane surface, many microplates densely packed on the membrane surface only allow water and small molecular water substances to pass through the liquid, while substances whose volume exceeds the micro diameter of the membrane surface are intercepted to the inlet of the membrane. On the liquid side, it becomes a concentrated liquid.

2. Application range of pvdf ultrafiltration membrane

a. Generally used to separate bacteria, pyrogens, colloidal solutions, floating residues and biological macromolecular organic compounds;
b. In the preparation process of purified water and ultrapure water, it is used as terminal equipment for RO reverse osmosis pretreatment and ultrapure water;
c. Purification of daily water and pure water;
d. Concentrate, purify and react in alcohol, enzyme preparation, pharmaceutical and other industries;
e. Able to concentrate and separate fruit juice;
f. Separation, concentration and reaction of soybeans, dairy products, sugar industry, tea pickles, vinegar, etc.;
h. Used for separation, concentration and purification of biopharmaceuticals, pharmaceutical products and their food industries;
i. It can also be used for terminal equipment treatment in blood night treatment, sewage treatment and ultrapure water production.

The application range of the pvdf ultrafiltration membrane includes the above aspects, and its use is indeed quite common, and it is even used in daily life.
