Water purification, true need
The appropriate and safe drinking water supply represents a permanent effort in the improvement of public health and the quality of life in the population of many communities. The vast majority of inhabitants in developing countries suffer from serious health problems, associated with insufficiency or water pollution. In the world, more than three million children under five die annually, as a result of diarrhea caused by microorganisms that are transmitted in water. Drinking water is not only naturally contaminated by microorganisms, but also by different substances or other ways that involve human activities. Water is naturally contaminated by some substances or free elements such as sodium, potassium, copper, iron, calcium and selenium. The substances introduced by human activities include salts, oil-derived hydrocarbons, solvents from industry and agriculture, as well as leachate of garbage deposits, latrines and black well.
The common water conversion process in drinking water is called purification. It usually consists of a stripping of volatile compounds followed by the precipitation of impurities with flocculants, filtration and disinfection with chlorine or ozone (Romero, 2008). On the other hand, some treatment of wastewater that involves floating macrophytes that have proven efficient in water remediation with nutrient content, organic matter and toxic substances such as arsenic, zinc, cadmium, copper, lead, chromium, and mercury. Its importance lies in its ability to be used in rural nuclei due to its low conventional energy consumption and practicality in the assembly and operation of treatment systems. Even so, the processes that take place in wastewater purification with floating macrophytes have not yet been rigorously clarified (Marslo and Lara-Borrego, 2012).
As treatment alternatives, hunting and moringes an deciduous arborescent species belonging to the convoling family that grows in the Tropical Pan region. Native of Mexico, is known as white hunting, straight hunter, meek hunter, Ozote, Blanco Pal.It is a kind of great attraction, since at times of flowering, the Alba Caples cover the entire Tree Cup. In addition, it is a plant used in popular medicine due to its medicinal properties.Among the uses of the hunting is the purification of the water from the key (Vázquez-Chacón, 2011).
On the one hand, water can be used for irrigation in areas where access to this resource is difficult. It is also promoted for its non -potable use in urban and rural areas, achieving considerable savings to be able to reuse treated water. At the same time, its implementation in disadvantaged areas or that have suffered natural catastrophes allows access to an acceptable quality water, avoiding the proliferation of diseases (Duran-Juárez and Torres-Rodríguez, 2006)
In addition, a system is achieved that provides industries with a more economical waste purification system, environmental respectful and ensures compliance with current legislation with respect to the levels of pollution allowed for water recycling or its dischargeto the public channel.
