Microfiltration membrane generally refers to a filtration membrane with a pore size between 0.1 and 1 micrometer. The microfiltration membrane can intercept particles between 0.1 and 1 micrometers. Microfiltration membranes allow the passage of large molecules and soluble solids (inorganic salts), but will retain suspended solids, bacteria, and high molecular weight colloids. The operating pressure of the microfiltration membrane is generally 0.3-7bar. Microfiltration membrane filtration is an early developed and applied membrane technology in the world, using natural or artificially synthesized polymer compounds as membrane materials. For microfiltration membranes, the main separation mechanism is screening and interception.

Shandong Bona has established long-term and friendly cooperative relationships with numerous global organic membrane component suppliers. We have introduced a large number of high-quality imported organic membrane components, membrane modules, and organic membrane accessories. We provide a variety of materials and molecular weight retention roll ultrafiltration membrane components, which are compact in structure and have a reasonable surface area/volume ratio. By using different flow channel networks, the width of the material liquid flow channel can be changed to adapt to various viscosity of the material liquid. We can also select suitable ultrafiltration membranes for customers based on their different process requirements, treatment systems, and related technical requirements.

1. Separation efficiency is an important performance characteristic of micropores, which is controlled by the pore size and pore size distribution of the membrane. Due to the fact that microporous filtration membranes can achieve relatively uniform pore sizes, the filtration accuracy and reliability of microfiltration membranes are high;

2. The surface porosity is high, usually reaching 70%, which is at least 40 times faster than filter paper with the same retention capacity;

3. The thickness of the microfiltration membrane is small, and the loss caused by liquid adsorption by the filtering medium is very small;

4. The polymer microfiltration membrane is a uniform continuum that does not shed the medium during filtration and does not cause secondary pollution, thus obtaining high-purity filtrate;
