With the gradual advancement of water treatment technology in my country, the application of reverse osmosis element membrane is becoming more and more common. It is a key component of osmosis membrane filter. However, during the entire application process, reverse osmosis element membrane will find that the pH of the effluent will decrease, and customers will worry that the safety of the water will be lost.
The pH of the reverse osmosis water has always been lower than the pH of the reverse osmosis water, which is related to the pH of the source water (ie bicarbonate). The bicarbonate in reverse osmosis concentrated water is concentrated 3-4 times, mostly in a saturated state. According to the equilibrium curve of bicarbonate, sulfide and CO2 with pH changes, the CO2 concentration value increases. Since reverse osmosis cannot intercept steam, the CO2 concentration value of cold water and concentrated water is basically the same, and the CO2 concentration value is also higher, so the pH value of the off-edge water decreases.
The above is the analysis of the reasons why the pH of the effluent of reverse osmosis element membrane has decreased. If there are other problems during the application process, you can contact the customer service to solve them.
