Thawed (recrystallized) water is a result of melting of ice, formed by freezing the original volume of water. Due to crystalline structure of ice, the presence of impurities in the crystal lattice, including various dissolved salts, is minimal. Since the pure water and contained impurities/ salts have different freezing temperatures, the ice crystal lattice “pushes out” the impurities to the non-freezing fraction, which can be easily separated from the remaining pure water. In comparison with tap water and artesian water, melt water is soft, it contains no harmful impurities, the concentration of heavy metals is negligible, pH value in it is greater by 0.2 - 0.5 units, the hydrogen peroxide concentration is larger and there is less oxygen. Filtered water is a product of chemical and/or ion-exchange treatment, which removes completely some of the elements from water, but introduces other substances from the filter itself. In comparison with filtered and bottled water, ice water contains the necessary for people mineral composition, and does not contain antibiotics, preservatives, flavorings and other artificial additives. Useful properties of melt water can be actively used in the production of cosmetics, food, especially aimed at anti-ageing and prolonged healthy life. To date, the melt water is present at the market only in the form of bottled water. However, this technological option may nullify all useful properties of melt water, since the question of their preservation in time ("memory") is not investigated. In addition, the price of commercially available water is comparable with the prices of premium bottled water, even without the delivery costs. Preparation of melt water at home is a complex and time consuming process. Manual water freezing in fridge makes it impossible to regulate and control the freeze rate. The Russian company from Novosibirsk has developed a technology of production of domestic technical systems (devices) for preparation of melt water. The principle of operation of the device is simple: the working volume is filled with raw water; the device automatically analyzes its main parameters (temperature, etc.) and chooses the appropriate mode of preparation (time, speed, modes of the process). At the freezing phase, the device sets the timing for impurities to be separated (to form a "brine") and pours it off into a separate container (tray) or drains. Without the impurities, ice undergoes "soft" defrosting resulting in the melt drinking water. The device has a number of additional automatic features, including self-cleaning, which helps to maintain the hydrosystem clean. The device is easy to use and maintain, it is fully automated. To prepare the device for use, one only needs to pour in water (1,7 liters). Further preparation of melt water (6-8 hours) goes in automatic mode. In economic terms, the cost of 1 liter of melt water is about 5 times less than the cost of bottled water. Thus, the technology makes this kind of water much more available for consumers, while maintaining its useful properties. The device’s parameters: Power consumption (at 220V/~50Hz): 280W Dimensions: 387 mm (W) x 377 mm (D) x 363 mm (H). Weight: 12 kg. Performance of the device is 3 liters of melt water per day.
