Water is the lifeblood of this is the core body of the organization, a broker for many chemical reactions. And its uses in all areas of life are innumerable; it is almost devoid field of industrial, agricultural or other water main. In some areas, it can not be used directly as a source must be purified. And water purification means plankton or remove all impurities and contaminants present to produce drinking water. And has used several methods to purify water, including: filtration and the use of chlorine, UV, ozone and others. And enclosed sand water, bacteria, fungi, toxic heavy metals, and other materials that spoiled. The pollution of the water environment of the defect and the damage, and displays a serious illness in humans; there are many diseases that lead to death because of water pollution, including cholera and typhus disease, and the spread of these diseases infect an epidemic. The water technical stages; Valtrchih and add chlorine and eliminate Ekorh water, but some of these roads polluted environment, and some friends have a more safety and health. Technologies such as the use of ultrasonic waves Vboisttha is to get rid of some organisms, such as bacteria and algae, and the smell of the water is good. Thus, at least the use of chlorine in the purification, it causes problems of chlorine to human health.
 Water treatment and purification techniques are changing day by day, depending on the evolution of technology, and discovery purifier and disinfectant materials for water security and health more than his predecessor . Conventional treatment methods were simpler and less complex than modern methods, and treatment of surface water and groundwater as well. The increased use of organic materials and chemical pollutants lead to increased water pollution, which increases the difficulty purified and transformed; water requirements for purified liquidation and appointment of sediment and ventilation to increase the dissolved oxygen content in which to improve the taste of water and make it palatable and should be boiled to kill the micro- bacteria and organisms like bacteria and then exposed to UV radiation with the sun, and works to kill the remaining bacteria and these simple steps which are used to purify water, but on a larger scale is the use of modern equipment for the purification and treatment of water. The method used in the purification of water depends on the water source and the purpose of their use. Vary the proportion of the addition of chemical disinfectants for water according to the above factors, and chemical disinfectants used for this purpose, but iodine are then added materials to eliminate the taste of iodine water. Then use disinfectants and other flavor enhancers, and back of the technique called new solar purification kill water contaminants. Ultimately, water is desalination, 
which is set operations are performed on water to remove excess salts and minerals, to become drinking, agriculture and industry, and is desalted desalination plants water that need large amounts of money and energy. And methods of water desalination for many types of them distillation. But the problem in desalination processes, they are expensive and consumers of non-renewable energy, and increasing environmental pollution. So we should look for other ways to desalinate water safer and less harmful to the environment, such as renewable energy and clean, she and other methods to use.
