One. The water usually contains five kinds of impurities: 
 A, electrolytes, including charged particles, common cations H +. Na +. K +. NH4 +. Mg2 +. Ca2 +. Fe3 +. Cu2 +. Mn2 +. Al3 +, etc.; anions have 3 -; B, organic substances, such as: organic acids, pesticides, hydrocarbons , alcohols and esters; C, particulate matter; D, microbial; E, dissolved gases, including: N2, O2, Cl2, H2S, CO, CO2, CH4, etc.; 
 The so-called de-ionized water, ultra pure water, high water, the depth of water purification is to remove these impurities. Impurities to the more thorough, the more pure water. 

 II. Deionized water, ultra pure water, high water effect: 
 Over the years, many of our enterprise product quality, process management has been strictly the case, remains unstable, with foreign products have a big gap, it is likely that production of water problems. If you use deionized water, then the situation will be greatly improved, many industries in China to improve product quality, and catch up with the world advanced level is one important means. This, we in practice, such as chemical, biological, painting, surface treatment, pharmaceutical, food, electronics and other industries have been well verified. 

 Three? I bottled distilled water, ultra pure water, high pure water production process:: 
 1. Raw water → sand filter carbon filter → → → softening precision filter → RO reverse osmosis system mixed bed → → → Terminal fine filtration of bottled water (water that is more than can be achieved 15MΩ.cm 0.066 μs / cm below 25 ℃) 
 2. Raw water → sand filter carbon filter → → → softening precision filter → RO reverse osmosis pure water tank system → EDI → → → pure water pump precision polishing mixed bed filter → Terminal → bottled water (water can reach 18MΩ. cm above the 0.055 μs / cm less, 25 ℃) 

 Note: I deionized water customers throughout the country, is widely used in semiconductor materials, devices, printed circuit boards and integrated circuits and ultra-pure ultrapure materials, laboratory chemicals, laboratory and pilot automotive, appliance surfaces other high-tech polished refined products.
