Comparative Assessment of Some Water Kinds in Our Country at the Source, During the Technological Process, up to Production-Ready

Abstract

Water is one of the main ingredients for consumption and for use in the food industry, it has a high strength solvent to salts therefore, depending on the chemical composition of the layers from which water passes, enriched with various substances and thus has a content of different chemical. Water used for consumption and industry should be drinking; such a characteristic is determined by the requirements of different nature, such as those organoleptic, chemical and bacteriological. Liquids the temperature falls shrink and lose volume. By lowering the temperature and density increases so that those parts are made more severe cold. For this reason, solid state liquids are heavier than their normal states of liquid. Water than from all other juices falling shrink to a certain temperature (+40C) and then immediately abruptly begins to swell. When it freezes, it expands even more. For this reason the solid water is easier than its liquid state. So, instead of ice water swim by the laws of physics should sink to the bottom of it.With the ice melting or evaporating water absorbs heat withdrawn from the surroundings. When the opposite happens, the heat given off. This action represents the physical action called "hidden heat". All fluids possess hidden heat. Only heat the water that is regarded as the highest of all. Thermal capacity of water, ie the amount of heat (energy) the right to increase the water temperature one degree, is higher compared to all liquids. The thermal conductivity of water, ie the ability of heat conductivity compared with other fluids is almost four times greater. Water should be easier and less mineralized. The amount of minerals dissolved in water is a basic indicator for the natural mineral water, the label in the form of parameter "dry residue at 180C in mg / l". The lower this value is, the better is the water. This study takes into account the scientific evidence of the above, where the resources at any time of the year there are no variable composition and chemico-physical and to maintain equal treatment of the quality regulated by the technological process from storage, filtering varied and up on the packaging.
