| Outline of Final Research Achievements |
It is researched the permeation performance of the hollow fibers module with PRO (Pressure Retarded Osmosis). It is cleared that the module permeability is very low and about a tenth of a hollow fiber permeability. The main causes are the concentration polarization and the reduction of the effective film area. The reduction of performance in fresh water flow caused with the concentration polarization and the least flow rate. It is pointed out by the high accuracy simulation that the optimization of the module geometry is very important and it can be obtain the three times higher performance than the conventional module.
