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.
