Distilled water: water condensed by distillation so there is very little inorrided salt in it. If only after a distillation of the water inside although those non-volatile parts (salts) are removed but the volatile parts of the water (ammonia, carbon dioxide,organic things) will still enter the distilled water. .

from tap water to deionized water generally goes through a few steps of treatment first through quartz sand particles thicker impurities and then through the yin and cation exchange column in turn to remove ions and then pressurized through Reverse osmosis membrane finally also generally has to go through a step of ultraviolet sterilization to remove the watermicroorganisms If the resistivity has not yet reached the requirements at this time, can be another ion exchange and reverse osmosis process and distilled water is only gasification and condensation purity is generally not as good as deionized water in the actual semiconductor industry used in most of the deionized water.
