Technical points of using new RO reverse osmosis membrane:
1. First, wash the quartz sand and coconut shell activated carbon, and wash the newly installed quartz sand and coconut shell activated carbon for a long time.
2. Check whether there is residual chlorine. If the residual chlorine exceeds the standard, solve the problem of residual chlorine, and then proceed to the next step of RO reverse osmosis membrane.
3. After the new membrane is installed, water it and soak it for 1 2 hours. Because it is a dry membrane, the soaked membrane is relatively wet to prevent damage to the membrane due to too high pressure.
4. Then start the high-pressure pump, and the pressure should be slowly increased from 2kg to 8 10kg, which has a better effect on the desalination rate of the new membrane.
5. Residual chlorine shall be controlled below 0.003.
6. Open the concentrated water valve before starting the high-pressure pump, and slowly adjust the concentrated water valve after the high-pressure pump is started to control the recovery rate of single membrane by about 15 percent .
7. The produced water in the first half hour must be drained because there is a protective liquid in the membrane to avoid affecting the taste of the water.
8. Detect the pH value of influent, which is above 6.5.
