Purification Of Water With Ultra Violet Light

Purification of water with ultra violet light in recent years are have been doing research to supplant the current systems of water treatment based on chlorine, with more efficient systems in terms of energy, and effective in health terms. The use of chlorine-based systems have the disadvantage that there certain viruses that are difficult to remove with them, and chlorine production has a high energy cost. These new systems that is gaining increased popularity is the system of purification by ultraviolet light. The main advantage of UV systems is that they do not introduce chemicals in the water. Likewise nor creates sub products, does not alter the taste, ph, or other properties of water. It is compatible with current plumbing systems, they are easy to install and its maintenance cost is relatively low. In addition, is not known any micro organism that is resistant to UV rays. Purification UV lamps produce a radiation of one far higher than that of the solar light intensity.

In most lamps, radiation is concentrated in 254 nanometer region, since this range of light is that has older germicidal. The majority of ultraviolet purification systems are combined with various forms of filtration. This is because these systems kill microorganisms existing in the water, but can not remove them of it by itself alone. Water with ultraviolet purification systems use a lamp that is protected by a transparent cover. The lamp is mounted so that any water that passes by the camera is exposed to rays ultra violet. The intense ultraviolet light damages the structure of the DNA of cells, this makes them sterile and prevents their reproduction. These cells are now dead and no more a threat. He is recommended for more complex organisms have previous activated carbon filter since the time of exposure to UV rays is not always sufficient to eliminate them completely.
