| titleOfInvention | Hollow fiber type semipermeable membrane, process for manufacturing same, module and water treatment process |
| abstract | To provide a hollow fiber type semipermeable membrane which achieves both water permeability and selectivity in high level and which can perform efficient treatment using small membrane area in such a water treatment utilizing the concentration difference from high concentration liquid having high osmotic pressure. n A hollow fiber type semipermeable membrane which is characterized in that, when an aqueous solution of 25°C having NaCl concentration of 35 g/L and pressure of 1.0 MPa is flown into an outer side of the hollow fiber type semipermeable membrane having length of about 70 cm while freshwater of 25°C having NaCl concentration of 0 g/L is flown into an inner side of one open end of the hollow fiber type semipermeable membrane and discharged from another open end at 10 kPa or less, the permeation flow rate is 30 to 70 L/m 2 /day, wherein said permeation flow rate is measured under such a condition that twice of the permeation flow rate flown from the inner side to the outer side of the hollow fiber type semipermeable membrane utilizing the concentration difference as a driving force is equal to a flow rate flown into the outer side of the hollow fiber type semipermeable membrane and that the discharged flow rate from the inner side of the hollow fiber type semipermeable membrane is equal to 10% of said permeation flow rate; the hollow fiber type semipermeable membrane is further characterized in that the inner diameter thereof is 50 to 200 µm; and that the hollow ratio thereof is 24 to 42%. |
