This treatment involves the construction of large lakes, where there is an appropriate residence time to reduce the organic content of water.
It is an easy and efficient method for treating wastewater from the sanitary sewer. The system is initially composed of a group of traps that trap and separate the solid parts not related to the design of the system in stages following their waste water and passed to a system of lagoons (one or more) where they remain in contact with the environment mainly the air, a process of oxidation and sedimentation, thus transforming the organic matter in other types of nutrients that become part of a diverse community of plants and aquatic bacterial ecosystem.

Rubber is a polymer of many units, a hydrocarbon chained elastic isoprene C 5 H 8, which appears as a milky emulsion (known as latex) in the sap of several plants, but can also be produced synthetically. The main commercial source of latex are Euphorbiaceae, genus hevea, such as hevea brasiliensis. It's overwhelming other species such as rubber elastic Urceola Funtamia Asia and West Africa supple. These have not been the main source of rubber, although during the Second World War, there were attempts to use such sources, rather than natural rubber was supplanted by the development of synthetic rubber.
The raw rubber obtained from other plants is often contaminated by a mixture of resin to be drawn so that the rubber is suitable for consumption. These rubbers are gutta-percha and balata, which are extracted from certain tropical trees.

Water is one of the most abundant throughout the world, is an element that can be found in different states, depending on the environment and the processes they undergo. Thus in cold weather locations can be found in the water environment in solid and liquid, as well as a gas, in tropical climates the temperature of that element, such as minerals that have are different. Similarly there are several types of water among them are: salt water, wastewater, freshwater and potable water among others.
This vital resource is the basic element of vaporization systems for different purposes, one of these is the treatment of water, may prepare it and return the environment to be reusable.
