Treatment Stations
These facilities are essential to avoid the pollution by wastewater, doing a partial removal of the pollutants and allowing the nature to complete the process within the water body acting as receptor (river, ocean...).
Thus, the level of treatment is function of the natural purification capacity of the water body. At the same time, this capacity is function of the volume and the oxygen content within the water body. Therefore, the targets of treatment stations are to give back water to the nature and to get a solid residue or sludge available for disposal or reutilization.
