Membrane Technology and Filter Membranes
Working without the additional chemicals, and with the character of energy-saving and easy to arrange, membrane technology becomes a popular separation technology in the lab.
Membrane technology is a big concept of different separating processes, but all the processes have a common ground that they are all based on the presence of semi-permeable membranes.
You will find that the principle of membrane technology very easy to learn: the filter membrane that has selective separation wall, is acting as a special filter which is not only letting the liquid flow through but catching the suspended solids and other substances.
There are lots of methods to make substances penetrate a membrane in applications. High pressure, the introduction of electric potential and the maintenance of a concentration gradient on both sides of the filter membrane are often used to work it out.
You can find Hawach filter membranes in two types: round disc membrane filters and roll type membrane filter. Both of them can be used for filtrating and sterilizing liquids, gas, and other samples. With different pore size and materials such as PTFE, PVDF, Nylon, MCE, CA, PES, GF, PP and etc., Hawach filter membranes can remove all micro-organisms and particles, without any chemicals disturbing during the process.
