The deionized water equipment is an ion exchange system. The ion exchange method system software is a traditional sewage treatment process that uses anion and cation exchange columns to exchange various anions and cations in water. The combination of anion and cation exchange columns according to different proportions can form the ion exchange method cation bed system software. So, what kind of deionized water equipment processing technology can generally be divided into?

The first method is to obtain deionized water using a cation anion exchange column. Generally, after passing through, the conductivity of the effluent can be reduced to below 10us/cm, and then it can be achieved below 1us/cm through a mixed bed. However, the water cost of this method is extremely high, and there is too much particulate residue to meet the ideal requirements. It has been adopted less frequently.

Second method: preparatory treatment (i.e. sand carbon filtration device+precision filter)+reverse osmosis+mixed bed processing technology

This type of method is commonly used at present. Due to the low operating cost of reverse osmosis, more than 90% of the positive ions in the water can be removed, and the remaining positive ions can be removed through mixed bed exchange. This can achieve a water conductivity of around 0.06. That's the most popular way now.

Third method: using a two-stage reverse osmosis method

The steps are as follows:

Drinking water multimedia filter, quartz sand filter, softened water processor, middle water storage tank, low voltage pump, precision filter, first stage reverse osmosis pH adjustment switching valve, second stage reverse osmosis (reverse osmosis membrane surface with positive electricity), pure water storage tank, pure water pump, microporous filter, tap water point

The fourth method is to apply reverse osmosis in the first solution, just like the second method. The mixed bed used in the later application is replaced by EDI continuous desalination membrane blocks, so there is no need for strong acid and strong alkali to rebuild epoxy resin. Instead, it is to rebuild electricity consumption. This completely makes the entire process zero pollution, and by solving the problem, the water body can reach over 15M. But this type of method requires more early project investment and low operating costs. Make appropriate project investments based on the situation of each enterprise. It can't be better. The steps are as follows:

Source water multimedia filter, quartz sand filter, softened water processor, middle water storage tank, low voltage pump, pH value adjustment system software, high-efficiency switching valve, precision filter, high-efficiency reverse osmosis, middle water storage tank, EDI water pump, EDI system software, microporous filter, tap water point
