Desalting reverse osmosis process and water treatment system

Abstract

The invention discloses a desalting reverse osmosis process and a water treatment system, belongs to the field of water treatment, and aims to inflate a ventilation partition plate to enable a pneumatic disc to extend and expand during reverse osmosis, so that on one hand, airflow of gas can play a role in blowing the extended and expanded pneumatic disc, the pneumatic disc is in a dynamic state and continuously generates flexible friction with the surface of the reverse osmosis membrane to achieve an auxiliary effect of washing dissolved salt impurities, on the other hand, the airflow can accelerate flowing of a saline solution at the reverse osmosis membrane, and the airflow is kept parallel to the reverse osmosis membrane; and compared with the prior art, the washing effect of the salt-containing water solution in the vertical direction is improved, damage to the reverse osmosis membrane is remarkably reduced, then the long-time continuous reverse osmosis effect of the reverse osmosis membrane is effectively guaranteed, the reverse osmosis efficiency is remarkably improved, and under the effect of the pneumatic disc, compared with the prior art, the flowing speed of a saline solution can be increased, and the desalting efficiency is improved.

Description

Technical field[0001]The present invention relates to the field of water treatment, and more particularly to a salt deficiency and water treatment system.Background technique[0002]Reverse osmosis is a membrane separation process in which the pressure gradient is dynamic, which can effectively remove dissolved salts in water as a molecular filter, which can remove dissolved salt colloidal bacteria and organic matter. The reverse osmosis process is the inverse process of natural penetration. In the process of producing a reverse osmosis process, a water-containing solution is applied to overcome the natural osmication pressure to overcome its natural osmosis, so that the water is dissolved in the water to dissolve the salt. The other side of the reverse osmosis membrane is blocked; at the same time to prevent the salt impurities from dissolving the salt impurities in the surface of the membrane, the concentrated water should continue to flush the film surface and the impurities in the...

AI Technical Summary

Problems solved by technology

[0003] In the process of desalting reverse osmosis water, the dissolved salt impurities focused on the surface of the membrane need to be continuously washed off by the brine solution, but because the brine solution washes the membrane perpendicular to the membrane, the flow speed of the brine solution is too fast , causing the membrane to be subjected to a large impact force, prone to deformation and damage, the flow speed is too slow, and the overall reverse osmosis efficiency is low
