The use of reverse osmosis industrial ultrapure water treatment equipment maintenance tips can not miss the article: In recent years, environmental pollution problems have not been solved, more and more water purification equipment appeared in a variety of production. Purified water equipment can prepare purified water dedicated to the production of products in industries such as biology, pharmacy, and medical equipment cleaning to meet the demand for high-quality water during the production process. Industrial reverse osmosis ultrapure water treatment equipment can effectively control the quality of the produced water and achieve industry standards such as sterile, pollution-free, impurity-free, and high-purity water. At the same time, it has also made outstanding contributions to people's healthy water and the earth's environmental protection. It also needs our daily maintenance. 1. For industrial reverse osmosis ultrapure water treatment equipment with high water temperature, reverse osmosis pure water equipment is prone to encounter the problem of high inlet water temperature in summer. Excessive water temperature is not conducive to the normal operation of pure water equipment, usually we prefer The method is to control the salt content of the influent water, reduce the operating pressure, and implement the decompression operation. According to the requirements of the water production volume, the pure water equipment shall be arranged to shut down and revise alternately. However, it should be noted that in order to avoid the growth of bacteria on the reverse osmosis membrane surface and increase the pressure drop, the shutdown time of each ultra-pure water equipment shall not exceed 24 hours. 2. Regarding industrial reverse osmosis ultrapure water treatment equipment shutdown and start-up treatment, the normal operation of industrial reverse osmosis ultrapure water treatment equipment needs to be shut down for rest or overhaul to ensure the health of the device and extend the service life, but a long-term shutdown will cause pure Depletion of water equipment. In theory, industrial reverse osmosis ultrapure water treatment equipment runs for at least 2 hours a day is a relatively healthy use time. Under special circumstances, if the machine needs to be shut down for more than 72 hours for repair, the industrial reverse osmosis ultrapure water treatment equipment should be maintained, and the components of the device should be filled with 1% sodium bisulfate and 18% glycerin for protection treatment with a chemical cleaning device. Every time the industrial reverse osmosis ultrapure water treatment equipment is shut down and started, the device should be flushed for 10 minutes under the condition of the inlet water pressure less than 0.4MPA. 3. Records about the operation and maintenance of industrial reverse osmosis ultrapure water treatment equipment. During the daily operation of industrial reverse osmosis ultrapure water treatment equipment, relevant parameters need to be observed and recorded on time, so as to closely monitor and promptly feedback and deal with problems when abnormalities are found. Among them, the PH value, conductivity, pressure, SDI, water temperature and other parameters of the water inlet of the pure water equipment are the parameters that need to be recorded in detail and accurately. The conductivity, flow rate and PH value of the produced water are important parameters to measure the normal operation of the equipment. The inlet water pressure value at each stage can reflect the problematic links that may occur in the process. 4. Low-pressure flushing Regular low-pressure flushing of industrial reverse osmosis ultrapure water treatment equipment in accordance with the maintenance regulations will help remove the stains attached to the reverse osmosis membrane and maintain the stability of the membrane performance. 5. Outage protection Due to production reasons, industrial reverse osmosis ultrapure water treatment equipment often needs to be shut down, which will affect the performance of the reverse osmosis membrane. In severe cases, the performance will be lost and cannot be restored. Low-pressure flushing can be used to reduce the impact during short-term outages. It is worth noting that the temperature of the water used for flushing should not be too low, otherwise it will affect the reverse osmosis membrane and cause the membrane to deteriorate. Long-term outages must be cleaned and protected with fungicides. 6. Chemical cleaning of the reverse osmosis membrane. Under normal conditions, inorganic substances, microorganisms, metal oxides and other substances attached to the reverse osmosis membrane will reduce the processing capacity of the reverse osmosis membrane and cause fatal losses. In order to maintain the water permeability and desalination effect of the reverse osmosis membrane, the reverse osmosis membrane should be chemically cleaned.
