Definition of sewage

Sewage call that kind of water that is contaminated with faecal substance and urine, that just come from organic waste both animals and humans. The name of black water makes sense because just presenting them are black. The main motivation that will lead to these waters to the submission to a special treatment are pathogens found in them, from excretion of humans and which may cause diseases and infections if not it is correct.
Such a situation is that the sewage also called as waste, sewage, sewage, water Yes or Yes demand a careful system of treatment which main task the channel the same, treat the residual content mentioned, and of course to evict them to avoid the major problems that cause: environmental pollution and proliferation of viruses.
There are different types of treatment, which are closely linked to the contamination that exists. In the case of suspended organic and inorganic matter, it is common that use sedimentation and filtration. On the other hand, for the dissolved matter are commonly used biological procedures such as for example the chemical oxidation.
Sedimentation withdraws that matter solid but thin, either organic or inorganic water, breaking through a device in which materials are retained to be disposed of afterwards.
On the other hand, filtering, or separate the suspended solids from a porous medium that retains precisely to solids and leaves that pass the liquid.
It should be noted that this type of water flows through what is known as a sewer, collector or sewer, which integrates the public sewer, built under the ground, usually in those avenues and major streets. Meanwhile, each of the dwellings of these streets are connected to the same to evacuate so satisfactory and controlled the wastewater or sewage.
Both the collector and the union of housing must be designed with a certain slope to allow the flow of water. Meanwhile, joints must remain sealed to avoid that these waters will leak to the ground.
