In urban waste water treatment, the water line is divided into four steps: pretreatment, primary, secondary and tertiary treatments. The first step is carried out by physical processes in order to prepare the water for subsequent phases. In the second stage, a physical-chemical treatment is carried out which allows the suspended particles flottation, followed by a biological treatment, consisting in the assimilation of organic material with oxygen.
