Water is one of the most abundant natural resource that exists on the planet, but a large percentage that can not be used in either environment that is salt water, waste water or contaminated by any harmful elements. In the treatment that is done to purify water or reusable again, is that dedicated to wastewater on time and is characterized by separating the liquid from all those elements or organisms harmful to human life.

Since that separation is the treatment of water and mud, which are the processes by which work is impure elements that make water. The best treatment is to separate sludge solids which are larger than those carried out at an early stage, with those so-called bio solids that correspond to a secondary stage of wastewater treatment, toxic compounds (organic and inorganic). The presence of toxic elements such as heavy metals, hinders the performance of mud as useful the environment, so the goal is to minimize the existence of microorganisms and organic matter type in the same mud, so that to be used not cause disease.

The purification of different types of water is conducted through various treatments and processes to the characteristics of them. In the case of wastewater treatment has three stages, primary, secondary and tertiary education, within each there are different procedures that undergoes this type of water to make it reusable.

Called primary treatment is done entirely with specific machinery and by itself for reducing fat, coarse solids, oils and amount of sand present in the wastewater.

Within society there are various types of water that imply different treatment according to whom it is intended or objectives that the systems want to achieve.

In the case of wastewater, water treatment takes place has a number of specific processes which can separate the fluid, pollutants or toxic components. The efficiency with which they perform wastewater treatment in each location will have a direct impact on the environment that covers a given society, because these processes are designed to last without polluting the water back to natural life. In the treatment of wastewater is important to note that the procedures the bacteria consume much of the oxygen, while those that feed on organic pollutants as defined. The fact that it consumes too much oxygen can cause you to change the ecology of the water completely, and therefore it is received.

There are currently undefined procedures by which treatment can be carried water to be purified or separated from the minerals and waste that detract from quality to it. Define the most appropriate treatment for water involves classifying the type of liquid you want to purify, since procedures vary for such work are made on salt water, wastewater, or water contaminated by industrial activity specific.

The various treatments that are performed in the case of wastewater can be classified broadly into physical and chemical treatments, biological treatments and chemical treatments, which have elements and special procedures and appropriate to this classification.

Among the different types of water that can be found, this residual water is commercial product, different industries or homes in a given society. This last is what has been responsible for raising certain standards to control and care of the different natural resources of each place in the world and the other foundations and other institutions working specifically to diminish the effects of such pollution.

In the case of the type of sewage water treatment will be specific and timely, depending on the type of contaminants that exist in the same and the degree of purity is desired. Usually these methods are often part of what is known as sewage treatment, in order to distinguish it from that purification is done in the case of drinking water treatment.

Water is one of the most abundant worldwide and is part of the most polluted or cloudy, located in rivers, seas, oceans and this is the last thing you can find the 97.25 water that exists throughout hydrosphere.
The seas and oceans contain salt water, this may be subjected to purification treatments thanks to the universality of its membership, giving patterns that contains element types and how they can extract or exploit them for use in various systems .

Part of a type of water treatment is called "osmosis", which consists in finding a certain balance of substances; here told two fluids enter and blend until unify the amount of dissolved substances containing separately. If this process is made containing a permeable membrane that separates and is in the midst of both fluids, the fluid that moves through the barrier will be less concentration of dissolved solids to the conclusion that has more of them. So eventually one side stay with more water, and this difference in level between the two fluids is called the osmotic pressure.

In the water treatment process and there is a fundamental component of primary importance, and is the container that is used to heat water at different temperatures, the boiler. The boilers are not only relate to processes that deal with this element, but exist eg for heating, this type of boilers operate through different fuels, which in the first instance involves the heating and in a second the distribution through a network of different pipes.

While many systems depend on the process that is performed with water in the boilers, that element is not always in an optimum state for use in relation to the different purposes.

At present a recurring problem is the care of water, scarcity of this element has caused serious problems throughout our country and it is extremely important especially in summer, knowing that water treatment can be done to care for and seize it. When water conditioning, food processing prior to a boiler, you can have 2 basic methods and fundamental one hand there is the external treatment and the other domestic water treatment.

Through either of these methods what is sought is to prevent corrosion and fouling tendency own water, develop and deteriorate the quality of it. The external water treatment is carried out based on a series of more specific methods such as cold carbonate Cal, Cal carbonate hot calcium chloride or sulphate and lime in cold and Coagulation among others.

The water that exists in the world is not a single type can be classified according to its composition containing mineral salts and are present in a given amount of liquid. These may be soft water, hard, alkaline and neutral that not only may differ in the amount of minerals they contain but also the type of minerals.

However, there is another classification of water, taking into account the origin of certain fluids such as salt water and wastewater among others. Water treatment by which a decision is taken to treat a given amount of fluid, is defined according to the type of water to purify desired, the volume to be treated and the result is desired. In this way the salt water treatment is done through a method called reverse osmosis, in which separation is achieved through greater pressure the concentration of salts and dissolved substances than is the liquid itself.

Most household and industrial water flow obtained through wells are in the need to implement a water treatment due to the fluid that comes from these tributaries often lead to significant damage to all elements which come into contact.

The reason for this becomes that this type of fluid has a high percentage of hard minerals such as magnesium and calcium, which generate corrosion and encrustation in pipes, faucets and appliances with which they come into contact. The solution to the problem is possible through a so-called softening water treatment.
