There are many issues that pure water equipment needs to pay attention to during the water production process, including operation steps and maintenance matters. Of course, there is also an important link, which is the monitoring indicators. What specific indicators need to be monitored? Below, the editor will provide a detailed introduction for everyone.

Establishing a sound supervision system for pure water equipment can ensure the quality and safety of purified water. If machinery and equipment encounter problems that you have not encountered before during the entire application process, we suggest that you do not blindly follow the trend for maintenance. You must find technical professionals to not only maintain the machinery and equipment, but also save you a lot of funds

1. Work pressure includes RO reverse osmosis seepage, seepage in each section, concentrated water, and commercial water. Under stable working pressure and temperature, the decrease in product water output indicates that the membrane has been contaminated by the environment. The conductivity includes RO reverse osmosis water infiltration and the conductivity of pure water for commercial use. The size of the conductivity reflects the salinity of the water, which in turn reflects the transformation of the water body for commercial use. The reduction of commercial water bodies reflects the environmental pollution process of membranes or other likely conditions, such as the damage of O-ring seals.

2. Operate the water seepage working pressure of each component in the pure water system production line and record it every 2 hours, as shown in the "Purified Water Production Line Operation Data Record". The standard solution for measuring pH, chloride ion content, and ammonia salt is uniformly prepared by the Quality Control Department and handed over to the pure water system for application. The pH, chloride ion content, ammonia salt composition determination method and standard specifications are the new version of the Chinese Pharmacopoeia Part II.

3. The total flow rate, working pressure, temperature, and conductivity should all be tested on a wired instrument panel. If there is a standard, the total flow rate of the automatic saving system software can be set to include the total flow rate of RO reverse osmosis seepage water, commercial water, and concentrated water, because the ratio of this total flow rate clearly determines the utilization rate of the reverse osmosis equipment. If the utilization rate is too high or too low compared to the design scheme value, it will have adverse effects on the operation. Therefore, ensuring the accuracy of the flow monitoring instrument panel is crucial.

4. Check the operation status of each component of the pure water system production line anytime and anywhere to ensure the normal operation of the pure water system production line. Query the data information on the display screen of the fully automatic detection system of the pure water system production line anytime and anywhere (seepage oxidation-reduction potential, effluent oxidation-reduction potential, terminal equipment water body, seepage oxidation-reduction potential is the first level RO seepage oxidation-reduction potential, effluent oxidation-reduction potential is the first level RO commercial water oxidation-reduction potential, and terminal equipment water body is the resistor after EDI effluent), and record it every two hours. Measure the pH, chloride ion content, and ammonia salt composition of a pure water system every two hours. And keep good records, as shown in the "Operation Record of Purified Water Preparation Post".
