A hollow fiber membrane is described the following; this procedure uses a quantity of long porous filaments that are packed in the body. Each filament in the hollow fiber membrane is extremely narrow in diameter. They are also very versatile. Its uses can be found by hollow fiber membrane in almost any type of filtration which ranges from micro filtration to the process of reverse osmosis. Hollow fiber membrane is therefore employed for the procedure for fiber filtration. The principle of the process is same as the one found in tubular and capillary filtration. The only distinction is that it uses a tube of small diameter so that you can provide flexibility. The method has a packaging density of high-value. This is feasible due to the small diameter that is strand. You can find certain filter configurations which might be possible using the flexibility of the strands which can be used are great. This configuration cannot be accomplished in filtration processes. Concentration Polarization is a process that occurs when pressure is placed on the feed side of the membrane. This can be done throughout the filtration process. In this procedure, the solute is totally or partially retained with all the aid of the membrane. This can then accumulate on the surface. This is the principal reason for using concentration polarization is a number of the pressure driven processes. In this method, the concentration of the solute steadily raises on the the top of membrane. This is from the flow which outcomes in the accumulation of the solute. This movement will later be balanced by the flux.
