Reverse osmosis membrane assembly, the rate of recovery of system can rise to 60% and 80% or so respectively, so that the cycles of concentration of system is risen into 5. by 2
The higher rate of recovery reduces the yield of system concentrated water, therefore reduces the treating capacity of subsequent evaporation device, thus can substantially reduce
The investment cost and operating cost of system.Relatively low operating pressure causes the aquifer yield of film relatively low, thus in the aquifer yield of system
The quantity of membrane module is higher needed in the case of certain, thus the cost of investment of system is higher.And super-pressure reverse osmosis membrane assembly
Higher osmotic pressure can be overcome, because intake pressure raises the net pressure rise for causing driving counter-infiltration so that aquifer yield
Increase, and then reduce the quantity of membrane module, so as to reduce investment and the operating cost of system.
3. when the operating pressure rise of reverse osmosis membrane, film is also increased to the rejection of salinity.Because permeation flux
Increase with the rise of operating pressure, as the pressure increases, the quantity of solvent of permeable membrane increases and flux salt is constant, therefore salt rejection rate increases
Greatly.
4. when the salt content of raw water is in 25000-30000 mg/l, the open runner network pipe type high pressure of 75kg weight category is anti-
Permeable membrane element（STRO）（Non-stop layer pull bar）, the open runner network pipe type high pressure reverse osmosis membrane assembly of 90 feather weight（STRO）And
The open runner network pipe type reverse osmosis membrane assembly of super-pressure（STRO）Test data of experiment such as following table:
| Raw water salt content 25000-30000 mg/l | The system rate of recovery | Salt rejection rate | Membrane flux |
| The other STRO of 75kg weight category | ̴50% | 95% | 10LMH |
| 90 kilograms of rank STRO | ̴60% | 95.8% | 12LMH |
| 160 kilograms of rank STRO | ̴80% | 95.9% | 15LMH |
