RO is the abbreviation of Reverse Osmosis membrane, which means reverse osmosis in Chinese.
The general flow of water is from low concentration to high concentration, once the water is pressurised, it will flow from high concentration to low concentration, which is also known as the principle of reverse osmosis: as the pore size of RO membrane is 5 parts per million (0.0001 microns) of a hair, which is generally invisible to the naked eye, bacteria and viruses are 5,000 times more than it.
Therefore, only the water molecules and some of the beneficial mineral ions can pass through, other impurities and heavy metals are discharged by the waste pipe.

Test conditions: Test pressure: 100 psi (0.69Mpa)
Test fluid temperature: 25 °C
Test solution concentration (NaCI): 250ppm
pH value of test solution: 7.5
Single membrane element recovery rate: 20%
Notes
Regular flushing of the RO membrane is a common, simple and effective way to maintain the membrane.
It is a mistake to avoid flushing for fear that it will produce waste water, but to some extent flushing more frequently will actually reduce the proportion of waste water.

First of all, you should have a water pressure meter, you test the pressure of the waste water, if the pressure value is above 6KG, it means that the RO membrane may be blocked. Or you have a TDS or conductivity meter, you test the water quality if the TDS value of the water is very high, then the d
