RO (reverse osmosis) water purification system

Abstract

The invention discloses an RO (reverse osmosis) water purification system. The system comprises a pre-filter, an RO filter and a post-filter which are sequentially connected in series in the water flow direction, wherein a branch is arranged between a water inlet end of the RO filter and a water outlet end of the post-filter; a bypass electromagnetic valve is arranged on the branch; the post-filter is connected with a pure water faucet through a pipe. The problem that first effluent TDS (Total Dissolved Solids) of a high-flow RO system are out of limits according to a probe is solved; filtration of the whole RO system is adjusted automatically by adopting the effluent TDS probe for detecting the TDS of the water passing through the RO filter.

Problems solved by technology

[0002] At present, with the development of industrialization and the improvement of people's living standards, the pollution of water resources is becoming more and more serious, and people are paying more and more attention to the quality of water resources. For this reason, more and more water purification technologies are popularized. In the general civilian field, corresponding water purification products have also been promoted. When the reverse osmosis water purifiers on the market produce water, a large amount of concentrated water will be produced, and the concentrated water will be directly discharged into the sewer. caused serious waste

[0003] The reverse osmosis water purifier with the best filtering effect has been favored unprecedentedly, especially at present, a large number of reverse osmosis water purifiers are popular in the market, and a large number of reverse osmosis water purifiers have canceled the pressure tank that may breed bacteria and produce odors , but when the water purifier is not used for a long time, when the water is drawn for the first time, there is an infiltration process when the reverse osmosis membrane is passed through the water for the first time. During this period, a small amount of residual substances in the production of membrane materials will dissolve in the water and be washed out. At the beginning, the TDS of pure water exceeded the standard, and for users, the first time to use water is the most, which caused the pure water used most of the time to use water with TDS exceeding the standard

[0004] At present, this problem has not been effectively solved. Some manufacturers have set up light reminders. When the TDS exceeds the standard, it will display a yellow light, and when the TDS is normal, it will display a green light, warning users to wait until the green light is on before starting to take water. This has brought troubles to users. Because the water It keeps flowing, and there is a lot of pressure in my heart. I have to keep an eye on the water flow and the indicator light. The user experience is poor.
