The purified water equipment includes four levels: pre-treatment process, reverse osmosis pure water process, ultra purification process treatment, and meticulous process treatment. After being treated by multiple modules such as multi-stage filtration module, ion exchange of high-performance resin, ultrafiltration filtration system, UV lamp sterilization, etc., the electrical resistivity of the produced water from the ultra pure water equipment is very high. Not only are all impurities removed, but also bacteria and organisms are also removed.

The surface roughness of the purified water equipment must comply with the specific regulations for the production, cleaning, and sterilization of the purified water system. The solution to the surface roughness of stainless steel pipes, pipes, and other raw materials has a crucial impact on the system. According to polishing, the contact area of the internal surface of the system can be greatly reduced, which will be beneficial for reducing the residual amount and the risk of impurity adhesion during transportation in the purified water system; Beneficial for smoother and easier cleaning of the inner surface of the purified water system; Beneficial for preventing microbial sedimentation and reproduction, providing reliable assurance for meeting the microbial limits of the system.

Maintenance of reverse osmosis unit for purified water equipment:

1. Regularly check and test the conductivity meter and various pressure gauges on time to ensure their normal and accurate operation.

2. Regularly inspect the electrical control system on time to ensure the normal operation of the equipment.

3. Regularly inspect the high-pressure pump and RO external pump on time, and replace the lubricating grease in a timely manner according to the maintenance manual.

4. Regularly record various operating parameters of RO equipment on time. Proposal: Record the operating parameters of each RO device every two hours.

5. As the running time increases, the membrane surface will adhere and precipitate, affecting the water permeability. Therefore, it is necessary to clean the RO components on time. If the pressure of each membrane element in the component exceeds 0.1Mpa, immediate cleaning should be carried out (cleaning is completed by the cleaning system). Take targeted treatment measures according to different pollution situations.
