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.

The bacteria that act in a particular place's natural environment, use those type of organic contaminants and microorganisms that cause disease in humans or animals. The same environment has factors that act to lessen the effects of these elements are harmful to health, found in wastewater, some of these natural factors are predation and a given exposure to ultraviolet rays.

Within what is artificial treatment to purify the water, this implies the concept of protecting people and all living things from those contaminants that can cause serious illness and sometimes even irreversible. It is the same as the main objective of the wide variety of products and packaging systems in the wastewater, is clean large amounts of water to later be returned to the natural system, making the receiver improved water use in subsistence.

In the case of this particular type of water is necessary to take into account that for reuse and return to the natural environment, because studies of the use of many of the ingredients used for disinfection for example, have shown that both water as the sludge (sewage products) are used largely in support of social and economic activities like agriculture. Still complete and finished the purification of wastewater, because it is destined to return to rivers and lakes, can have an adverse outcome than expected, by the nature of these pollutants but need a lower dose of the existing today.
