Brief introduction of ultra-pure water

Ultra-pure water treatment: not only the conductive medium in water is almost completely removed, but also the undissociated colloidal substances, gases and organic substances in water are removed to a very low level. The resistivity is greater than 18mω* cm, or close to the limit value 18.3mω* cm(25℃).

Ultra-pure water treatment is difficult to achieve in general processes. The resistivity can reach18.25m Ω * cm (25℃) by four steps of pretreatment, reverse osmosis, ultra-purification and post-treatment, and various treatment methods such as multistage filtration, high-efficiency ion exchange device, ultrafiltration filter, ultraviolet lamp and TOC removal device.

Ultra-pure water is produced by distillation, deionization, reverse osmosis or other appropriate supercritical fine technologies in order to develop ultra-pure materials (semiconductor raw materials, nano-fine ceramic materials, etc.). ) in the American scientific and technological community. Except for water molecule (H20), there are almost no impurities, bacteria, viruses, chlorine-containing dioxins and other organic substances in this water, and of course there are no mineral trace elements needed by human body. Generally speaking, this kind of water can't be drunk directly, which is harmful to human body and will precipitate from human body.
