Hollow Fiber Membrane Technology

As one of the world's leading companies in filtration, Cobetter has invested a lot of fund and technology to successfully develop hollow fiber membrane. The outer diameter of this kind of membrane is usually between tens to hundreds microns, and micropores are evenly distributed on its surface. Based on this unique structure, the lateral flow filtration other than dead end filtration can be realized, which can be applied to the technology for degassing liquids or dissolved gas control. Cobetter has developed PP, PMP and PTFE hydrophobic membranes with different characteristics to meet the requirements of various applications.


Advantages of PMP Material

·  PMP material has chemical resistance property same as PP.
·  The unique molecular structure endows PMP with superior air permeability.
·  PMP material has excellent hydrophobicity (low surface tension);
·  PMP can withstand liquid with surface tension above 35Dyne/cm.

Weaving Method And Flow Channel Design

How to make thousands of tiny fiber membranes into a complete filter is also a test of technology. Cobetter's unique weaving process makes the fiber membrane into an array, then it will be wound into a cylindrical shape and put into the membrane shell. This technology expands the effective contact area. At the same time, each fiber membrane is fixed and will not move with the flow of liquid, so as to eliminate broken phenomenon of fiber membranes and ensure the stability of the membrane contactor.


The inner structure of Cobetter's degassing membrane is equipped with a baffle and a central tube for water distribution, which makes the liquid form a jet state on the surface of the membrane, and effectively improves the gas transmission efficiency between the shell side and the tube side.











Degassing Membrane Function And Working Theory

In medical industry, the water used in the pipeline already has high enough purity, but the dissolved gases (such as O₂, N₂, CO₂, etc.) and visible bubbles in the water will be generated in various environments, or react with reagents, causing inaccurate sampling. These gases are bound to cause great interference to the micro quantitative medical test, especially the clinical test results.

 

The function of degassing membrane contactor is to remove the gas attached to the solution and eliminate the interference to the detection process and results. In a typical operation, the liquid flows outside the membrane, and the membrane is vacuumized or purged with gas. There are many micropores on the surface of hydrophobic membrane, which allow gas to pass through but prevent liquid from penetrating. The gas continuously moves to the inner part of the hollow membrane through the micropores and is taken away, so as to achieve bubble removal.
