摘要： A hollow fiber type semipermeable membrane which achieves both water permeability and selectivity in high level and performs efficient treatment using small membrane area utilizing the concentration difference from high concentration liquid having high osmotic pressure. The hollow fiber type semipermeable membrane 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/m2/day. An inner diameter thereof is 50 to 200 μm; and the hollow ratio thereof is 24 to 42%.

摘要： A reverse osmosis system in fluid communication with a fluid reservoir and a method of operating the same includes a pressure vessel having a membrane therein, a high pressure fluid input, a low pressure fluid input, a permeate output and a brine output. The system further includes a high pressure valve, a low pressure valve and a high pressure pump in fluid communication with the high pressure input through the high pressure valve. The system also includes a low pressure pump in fluid communication with the low pressure input through the low pressure valve. The high pressure pump and the low pressure pump are in fluid communication with the fluid reservoir. The low pressure pump initially fills the pressure vessel and the high pressure pump operates during permeate production.

摘要： A water treatment system including a reverse osmosis module and a control valve controlling communication between a water source and the module. A feedwater biased storage tank stores permeate and its pressurization by feedwater is controlled by a feedwater control valve. Flow of signal pressure to a signal pressure chamber of the feedwater control valve is restricted to reduce the rate at which a fluid generated force is applied. A check valve in parallel with the restriction allows relatively unrestricted flow out of the signal chamber when signal pressure is terminated. A tank pressurization control valve controls the operation of the feedwater control valve and controls the pressurization of a feedwater biasing chamber in the storage tank. Per-meate is stored in an accumulator for flushing the reverse osmosis module when the storage tank reaches a predetermined limit. Cleaning substances or additives can be introduced into the system.
