Purified water is the basis for the operation of both many industries and numerous laboratories - research and analytical. It is a basic chemical reagent and a medium that allows many reactions and processes to take place. In addition, it is an essential ingredient in some substrates. The production of purified water is a technological process that requires the use of appropriate equipment. Leading the way among these are water demineralizers and distillers used in more specialized applications. Water purification systems are the ideal solution that can meet all laboratory requirements for clean water. The most important part of working in a laboratory is the best and consistent quality of water. Such a system must meet several criteria such as the production of consistent and high quality water, energy efficiency, minimization of waste stream, high efficiency, maintenance-free system operation, low product temperature, constant quality control and also low operation and service costs. Production of ultrapure water is a necessity for the work of any laboratory. Demineralizers allow to purify water from the dissolved mineral salts and organic compounds contained in it. With the help of reverse osmosis, you can also get rid of mechanical and biological impurities (microorganisms) from water. Popular devices included in this group operate on the principle of reverse osmosis - water is pressed under pressure through a special semi-permeable membrane, and the resulting product is further "purified" on an ion exchange column. As a result, the obtained liquid is characterized by high purity and can be used for many laboratory applications. Some demineralizers have built-in components for the production of ultrapure water, so that from a single machine one can obtain both water for general-laboratory applications and ultrapure water used, for example, for sensitive molecular analysis. The advantage of reverse osmosis is the relatively low energy consumption, since the process proceeds without phase transformation of the water, i.e. there is no evaporation and condensation. The disadvantage of deionizers operating on the reverse osmosis principle is considered to be water-intensity, since for every liter of purified water produced, there are several to several liters of waste liquid. The above disadvantage is devoid of water purification devices, which operate entirely on the principle of ion exchange on a special bed. This source of clean water in the laboratory allows clean water to be obtained without additional electricity consumption, but requires periodic regeneration. In addition, it needs an appropriate selection of the type of ion exchange resin or other sorbent, depending on the chemical composition of the feed water. Such devices are ideal as a backup source of purified water for the laboratory. They will also work well wherever it is impossible to install a demineralizer or supply purified water. Distillers.This is a source of pure water in the laboratory that works on the principle of evaporation and then condensation of the liquid in a cooler. This process can be done in a single cycle or double. With the help of distillers it is possible to obtain water free of both mineral salts and dissolved gases in it. To achieve high efficiency of the process, it is necessary to use treated, that is, pre-treated water.Distillers make it possible to obtain very pure water for the most demanding tests. The disadvantages of distillers are considered to be the high consumption of energy required to evaporate the water and the consumption of water needed to condense the distillate, although some models use feed water for cooling, which is preheated in a cooler.
