What are the problems in the use of reverse osmosis technology of secondary reverse osmosis pure water treatment equipment? Author: Reverse osmosis water treatment equipment has a very good use of the chemical in the electronics industry. During the operation, the equipment was in good condition, but after one year of operation, the desalination rate of the secondary reverse osmosis pure water treatment equipment dropped significantly, and the amount of water produced was also greatly affected. The membrane difference in the system is significantly increased, which has a great negative effect on the reverse osmosis in the secondary reverse osmosis pure water treatment equipment, which directly makes the equipment unable to use normally. So what are the problems in the use of the reverse osmosis technology of the secondary reverse osmosis pure water treatment equipment? 1. The water quality has deteriorated. Most of the water used in the system comes from nearby rivers, and some places will be affected by the nearby seawater intrusion. The microbial content of the water quality itself will be very different, and the changes in the content will also vary greatly. This brings great difficulty to the pretreatment of water quality, and directly leads to a certain increase in the turbidity in the water treatment process. When the salt content increases, the conductivity of the water increases from 3800 to 5200, which directly affects the increase of the dissolving agent. From such an example, it can be seen that the water quality in the raw water source will respond to the conductivity, which will also shorten the mechanical life of the ultrapure water equipment. 2. The membrane body in the secondary reverse osmosis pure water treatment equipment is contaminated. In the inspection project, a large amount of brown sludge was found at the filter membrane. Checking the data again, it is found that the pressure difference in the membrane is much higher than before, and the water production is also reduced accordingly. It can be seen that the membrane in the reverse osmosis system is contaminated and severely blocked. It is difficult to have more sediments in the membrane module, and the equipment will also take protective measures according to the needs of the operating mode. If the management personnel do not operate according to the requirements, the membrane body will be seriously polluted, and the function of the membrane body will eventually decline. 3. The membrane body in the secondary reverse osmosis pure water treatment equipment is aging. The aging phenomenon is an irreversible change. In the actual water environment detection, it is found that in the pipeline with the filter system in the front, there will be a certain amount of residual cleaning liquid after cleaning. These strong oxidizing agents will gradually penetrate into In the reverse osmosis system, the chlorine content in the reverse osmosis system exceeds the standard and cannot meet the design requirements. After a long time of reaction, the membrane in the reverse osmosis system will be oxidized and cannot exert its due effect. This is the end of the introduction about the problems in the use of the reverse osmosis technology of the secondary reverse osmosis pure water treatment equipment, and I hope it will be helpful to everyone.
