A hollow fiber membrane is described as follows; this process uses a number of long filaments that were porous that are packed in the body. They are also extremely adaptable. Its uses can be found by hollow fiber membrane in almost any type of filtration which ranges to the procedure for reverse osmosis from microfiltration. Hollow fiber membrane is thus utilized for the means of hollow fiber filtration. The theory of this process is same as the one within capillary and tubular filtration. The only distinction is that it utilizes a tube of small diameter so that you can provide flexibility. The process has a packaging density of value that is high. This is possible because of the small diameter that is strand. You will find certain filter configurations that are possible using the versatility of the strands which can be used are great. This configuration cannot be accomplished in filtration processes. Concentration Polarization is a procedure that happens when stress is applied to the feed side of the membrane. This can be completed throughout the filtration method. In this procedure, the solute is partly or completely retained together with the help of the membrane. This can accumulate on the surface. That is the principal reason for using concentration polarization is some of the pressure driven processes. In this method, the focus of the solute steadily raises on the the top of membrane. The flux will later balances this convective movement.
