Maintenance Techniques for Purified Water Equipment

1. Strictly control the inlet water quality to ensure that the device operates under water quality conditions that meet the inlet indicators. If the inlet water quality does not meet the requirements, it can easily cause fouling and blockage of the reverse osmosis membrane, leading to rapid failure of consumables and seriously affecting the outlet water quality.
2. The total inlet water volume of reverse osmosis is controlled by the RO inlet control valve. If the inlet water volume of reverse osmosis does not change, do not move the RO inlet control valve, and it is strictly prohibited to fully open or close it. The RO concentration control valve is used to adjust the system recovery rate. If the recovery rate does not change, do not tamper with the concentration control valve, and it is absolutely forbidden to fully open or close it.

3. The device cannot be shut down for a long time and should run for less than 2 hours per day. If it is prepared to shut down for more than 72 hours, a chemical cleaning device should be used to fill the components with 1% sodium hydrogen sulfate and 18% glycerol for protection.
4. After each shutdown, the reverse osmosis device should be flushed for 10 minutes under the condition of a water inlet pressure of 0.4 Mpa.
5. Operating pressure control should take the lowest possible pressure value while meeting the requirements of water production and quality, which is beneficial for reducing membrane water flux attenuation and decreasing membrane replacement rate.
6. The operator should record the operating parameters every hour, check the usage of the pure water equipment and the quality of the effluent. The main recorded content should include: influent: pH value, conductivity, pressure, SDI， Water temperature. Water production: conductivity, flow rate, pH value, concentrated water: flow rate, pressure, and inlet pressure of each section.
