Microfiltration membrane generally refers to a filter membrane with a pore size between 0.1-1 microns. Microfiltration membrane can intercept particles between 0.1-1 microns. Microfiltration membrane allows macromolecules and soluble solids (inorganic salts) to pass through, but will intercept suspended matter, bacteria, and high molecular weight colloids. The operating pressure of microfiltration membrane is generally: 0.3-7bar. Microfiltration membrane filtration is an early developed and applied membrane technology in the world, using natural or synthetic polymer compounds as membrane materials. For microfiltration membrane, its separation mechanism is mainly screening and interception.

Bonatech has established long-term friendly cooperative relations with many organic membrane component suppliers around the world. We have introduced a large number of original imported organic membrane components, membrane assemblies and organic membrane accessories with excellent performance. We provide a variety of materials and molecular weight cut-off rolled ultrafiltration membrane components, which have compact structure and reasonable surface area/volume ratio. By using different flow channel networks, the width of the liquid flow channel can be changed to adapt to liquids of various viscosities. We can also select suitable ultrafiltration membranes for customers based on their process requirements, different treatment systems and related technical requirements.

Features:

1. Separation efficiency is a relatively important performance characteristic of micropores, which is controlled by the pore size and pore size distribution of the membrane. Since the pore size of microporous membranes can be relatively uniform, the filtration accuracy of microfiltration membranes is higher and the reliability is higher;
2. The surface porosity is high, generally reaching 70%, which is at least 40 times faster than filter paper with the same interception capacity;
3. The thickness of the microfiltration membrane is small, and the loss of liquid caused by adsorption of the filter medium is very small;
4. The polymer microfiltration membrane is a uniform continuum. There is no medium shedding during filtration, and no secondary pollution will occur, thus obtaining a high-purity filtrate;
