What are the advantages of the process design of ultrapure water treatment equipment in the electronics industry? Author: electronics industry is a demanding industry quality, ultra-pure water used in the electronics manufacturing industry more widely, mainly because of precision components and electronic products sometimes need water for cleaning or cooling at the time of manufacture, which requires water can not Containing any conductive material, otherwise the components will be damaged, so it will cause the extreme demand for ultra-pure water in the industry. As a result, a large number of ultra-pure water treatment equipment for the electronics industry appeared on the market. Now everyone chooses the equipment but also looks at the technology of the equipment. There are three main types of ultrapure water system processes, and other processes are basically derived from different combinations and combinations on the basis of these three types. Now the advantages and disadvantages of these three processes are listed here. 1. EDI electronic special ultrapure water equipment mainly uses ion exchange resin. The advantages show that the investment is small and the space occupied is not very large, but the disadvantages are also very obvious. It must be regenerated frequently, which will damage the environment to a certain extent. . 2. The second process uses reverse osmosis technology as the pretreatment device technology. The disadvantages of this process are more serious than the previous process. The initial investment is much higher than the previous one. The only advantage is the ultra-pure water for EDI electronics. The equipment regeneration time interval is relatively long, and it also pollutes the environment to a certain extent. 3. The third process also uses reverse osmosis as the device as the pretreatment equipment. The third method is nowadays that the production of ultrapure water is more economical and environmentally friendly, and it is not necessary to regenerate the equipment. , And the surrounding environment is basically pollution-free. But its disadvantage is that the capital investment is still too high compared to the above two methods.
