The hollow fiber membrane performance is examined in Forward Osmosis (FO). The original test apparatus is made to avoid the influence of concentration polarization, deviation flow and reduction of effective membrane area. A few hollow fibers are used in experiments of the permeation performance. It is cleared that the concentration polarization is very large influenced to the performance, about 40% reduction of performance. The performance of the conventional module model is about 1/2.5 of the hollow fiber that there exist the deviation flow and reduction of the effective membrane area.
