Ultra Pure Water Systems
ASTM Water Type l, Type ll and Type lll
Ultra-pure water is water that is almost or completely free of contaminants. Ultrapure water systems is an important component for laboratories of all markets. These ultra-pure water systems remove chemical contaminants through deionization (DI) and reverse osmosis. An ultra-pure water system eliminates bacteria with UV radiation. These laboratory water purification systems can achieve a resistance of 18.2 MOhm-cm (high resistance indicating low anionic contamination) and can reduce organic carbon to less than 50 ppb. An ultra-pure water system is equipped with ultra-filters to remove endotoxins, DNase and Rnase from bacteria can be destroyed by UV radiation, resulting in an extremely low total organic carbon (TOC). Additional carbon filters in these lab water purification systems reduce the need for pre-treatment, and allowing tap water to be used as a source.
What is Reversed Osmosis?
Reverse Osmosis is a physical procedure to concentrate the dissolved substances in liquid, in which the natural osmosis process is reversed under pressure. Osmosis describes the process of generating a concentration balance between two liquids through a semi-permeable membrane. This process always takes place when two aqueous solutions with different ion concentrations in water are used and separated by a semipermeable wall. Physiologically speaking, the ion solutions that are separated from each other by membranes always strive for a concentration balance. This means that ions from the side with a high concentration of solutes strive to arrive at the side with a lower concentration. Because the membrane forms a barrier that prevents the ions from migrating easily due to their molecular size, the smaller water molecules instead flow from the lower side to the higher solution concentration side. In reverse osmosis technology, the principle of osmosis described above is reversed. On the side with high ion concentrations (tap water, raw water), pressure is applied, forcing the water to flow in the other direction, i.e. to the other side, namely to the pure water side with the lower concentration.
