What are the hazards of EDI industrial ultrapure water treatment equipment working in a high temperature environment? Author: now live in EDI ultrapure water treatment equipment industry is a relatively common water equipment, and after many industrial enterprises to purchase the EDI industry ultrapure water treatment equipment, manufacturers will tell the user a number of considerations, and in the use One of the things that need to be understood and guarded against in the equipment is to avoid using it in a high-temperature environment, so why is the EDI industrial ultrapure water treatment equipment not suitable for operation in a high-temperature environment? Let's introduce the environmental protection below. This is because in a high temperature environment, the performance of the reverse osmosis membrane will be greatly negatively affected. We found from big data that when the water temperature rises, the salt rejection rate of the reverse osmosis membrane will decrease, which is inversely proportional. The reason is that in the fixed flow operation state, the increase of water temperature will reduce the viscosity and cause the increase of the water flow, which directly leads to the decrease of the operating pressure and ultimately the decrease of the salt rejection rate. Therefore, when the water temperature rises, we should take corresponding measures to adjust and maintain it according to the actual situation. In addition, the impact of high temperature is by no means limited to the drop in desalination rate. The increase in water temperature will give some microorganisms a good growth and reproduction environment, and the equipment will be polluted by microorganisms. Most bacteria are suitable for growth in water temperature of 15°C to 30°C. When the temperature rises, their metabolism and growth rate will increase. And when microorganisms enter the concentrated water section of the reverse osmosis system, the nutrients inside are the nutrients for its growth and reproduction. It can reproduce rapidly and form biofilms on the surface of the reverse osmosis membrane within a few days, which increases the entry and exit of the reverse osmosis system. The water pressure difference will not only reduce the desalination rate, but also reduce the water production, and the water produced will also be polluted. When EDI industrial ultrapure water treatment equipment is found to be contaminated by microorganisms, measures should be taken immediately to clean the equipment. Environmental protection recommends using 0.1% NaOH solution for chemical cleaning. The cleaning environment is that the water temperature is lower than 30 degrees Celsius and the pH value is 11-12. This is the end of the introduction about why EDI industrial ultrapure water treatment equipment is not suitable for operation in a high temperature environment. I hope it will be helpful for everyone to understand the precautions for use of EDI industrial ultrapure water treatment equipment.
