What are the factors of how to correctly use small and medium-sized fully automatic ultrapure water equipment at high temperatures? When the small and medium sized manufacturers in the automatic delivery of ultra-pure water equipment will be given special instructions to allow users to use the device to understand and prevent a number of issues, including avoiding use in high temperature environments, as well as installation of equipment: The authors The environment is also required. Then why is the small and medium-sized fully automatic ultrapure water equipment not suitable for working at high temperature? In fact, because of the high temperature environment, it will have a great impact on the performance of the reverse osmosis membrane. We can see from the data that the water temperature becomes higher , The salt rejection rate of the reverse osmosis membrane will decrease, which is inversely proportional. This is because when the equipment is running with the same flow rate, the increase in water temperature will lead to a decrease in viscosity in the equipment, resulting in an increase in water flow, which directly leads to a decrease in operating pressure and a decrease in salt rejection rate. Therefore, when it is found that the water temperature has risen, it is necessary to take corresponding reasonable measures for adjustment and maintenance according to the actual situation. In addition, the influence of high temperature is not limited to the reduction of salt rejection. Rising water temperature will create a good environment for the growth and reproduction of some microorganisms, which will cause the equipment to be contaminated by microorganisms. Most bacteria grow at a temperature of 15°C to 30°C. When the temperature rises, the metabolism and growth rate of the bacteria will also increase. If microorganisms enter the concentrated water area of u200bu200bthe reverse osmosis system, the nutrients inside are the nutrients for the growth and reproduction of microorganisms. On the surface of the reverse osmosis membrane, it can rapidly multiply and produce biofilms within a few days, increasing the water pressure in and out of the reverse osmosis system, which not only reduces the desalination rate, but also reduces the amount of water. Water can also be polluted. If small and medium-sized fully automatic ultrapure water equipment has been contaminated by bacteria, measures should be taken to clean the equipment immediately. We can choose chemical cleaning. The best cleaning environment is that the water temperature is below 30 degrees Celsius and the pH is 11-12.
