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.

Within what is the treatment of waste water type is a series of physical-chemical processes and biological processes that are performed in order to eliminate those physical and chemical pollutants and biological that may exist in water. The main purpose of subjecting the water to a series of purification processes is to achieve a wastewater that is clean and can be undertaken on the environment, and the other to get a mud or silt that is also reusable for other purposes and other uses.

The purification process of wastewater begins with sorting and separation of large solids, as a first step to obtain a more uniform liquid and capable of further elaboration. There is another way to separate large solids and is by crushing them by a specific machine and subjected to a system with a sand removal which will bring the liquid to separate those elements. This will separate solids achieved large and those wastes that are suspended in the water of this type.

After these processes the water undergoes a secondary settlement process, which is based on solid biological conversion by certain bacteria contained generally in the same liquid. Thanks to this last step, that biological material can be separated and the water can pass another more specific and additional processes to achieve further purification and become reusable over disinfection and filtration methods among others.
