Abstract: Forward Osmosis(FO) is recently paied attention to preprocessing of the Reverse Osmosis(RO). It can reduce the input power of RO plant. It is required to reduce the salt concentration at outlet and increase the permeation flow rate. In this paper, the characteristics of the fresh water flow and osmosis are studied for the hollow fiber membrane module used in RO system. It is cleared that the disappearance of fresh water and the concentration polarization in hollow fiber largely influence the reduction of permeation flow rate in the case of the low fresh water flow rate. Concentration of fresh water and the leakage of salt influence the reduction of permeation flow rate in the case of high fresh water flow rate.
