Ultrapure water (UPW), high-purity water or highly purified water (HPW) is water that has been purified to uncommonly stringent specifications. Ultrapure water is a term commonly used in manufacturing to emphasize the fact that the water is treated to the highest levels of purity for all contaminant types, including: organic and inorganic compounds; dissolved and particulate matter; volatile and non-volatile; reactive, and inert; hydrophilic and hydrophobic; and dissolved gases.

Compared with the traditional distillation method of ultra-pure water equipment, the ultra-pure water equipment combines the latest electric deidion (EDI) technology and has obvious advantages and advanced properties. 1. High efficiency and energy saving. There are mainly multistage distillation, high-pressure graded distillation and centrifugal purification distillation processes. All distillation methods were performed at high temperatures of 120°C, so completely sterile water was obtained. Therefore, the energy consumption in operation is considerable; since the high temperature, all equipment components must withstand high temperature impact, and the equipment cost and maintenance costs are high. Reverse osmosis technology combined with high efficiency ozone disinfection method, the whole system works at room temperature and low pressure, saving equipment investment, low operation and maintenance costs, reliable and energy saving: the operation cost of membrane treatment method is only 12-15% of the distillation method, which is very economical and competitive. 2. Stable and reliable. With the acceleration of industrialization, the discharge of large and complex waste components makes the worldwide pollution become increasingly serious, among which the pollution of water resources is more severe than before. Because the boiling point of volatile organic pollutants is mostly lower than the vaporization temperature of water, if not treated, it is easy to enter the distillation process, simple distillation method can not effectively remove it, must rely on activated carbon adsorption and other filtration methods, increase the instability of the system and water quality. The membrane process adopts multi-media filter for pretreatment; the microporous working principle of reverse osmosis membrane ensures that all large ions and molecules in water can easily remove volatile organic pollutants with larger molecular diameter, and fundamentally ensure that organic indexes meet the indexes specified in the Pharmacopoeia

Ultrapure water is the basis for successful analyses. Yet analytical methods are becoming more and more sensitive and thus more susceptible to interference. Consistently high water quality is decisive in ensuring the reproducibility of your results and in preventing time-consuming repeat analyses. The Qina Ultrapure Water Systems offer an exceptionally wide range of modular-designed systems for producing Type I ultrapure water for chromatography, mass spectrometry and many more applications.

Ultrafiltration (UF) is a water purification process in which water is forced through a semipermeable membrane. Suspended solids and high-molecular-weight solutes remain on one side of the membrane, the retentate side, while water and low-molecular-weight solutes filter through the membrane to the permeate side. UF can remove most organic molecules and viruses, as well as a range of salts. It has gained popularity because it produces stable water quality no matter the source water, has a compact physical footprint, removes 90-100% of pathogens, and does not require chemicals, except for cleaning membranes. UF was first described at the end of the 19th century, but the practical start of ultrafiltration as a separation process came in 1963, coming on the heels of the discovery of the asymmetric cellulose acetate reverse osmosis membrane in the 1950s, and MIT’s discovery of polyelectrolyte complex hydrogels at the beginning of the 1960s.
