1) The reverse osmosis assembly frame is not suitable for being arranged in the second floor, otherwise, the assembly frame is in a high position, and the membrane is easy to lose water when the valve is not tightly closed.
2) When the reverse osmosis is designed, a certain space is reserved on the water outlet side of the membrane shell, so that the scrapped membrane can be conveniently extracted from the water outlet side when the membrane is conveniently replaced.
3) The reverse osmosis group rack concentrated water drain pipe is preferably bent upwards to a height exceeding the highest membrane layer and then is discharged into a trench when designed.
The working principle of one embodiment of the utility model is as follows: the utility model uses the water treatment technology of separating substances by using the selective permeability of the membrane, so that the solvent in the solution is separated by the membrane, and inorganic ions, bacteria, viruses, organic matters, colloid and other impurities in the raw water can be removed, thereby obtaining high-quality purified water.
