Complete studies of the wastewater treatment plant building

The waste water treatment plant with a nominal capacity of 100 000 P.E. started operation on December 22, 2001.
It operates on the principle of low-load activated sludge, with nitrification/denitrification and biological phosphorus removal.
The pretreated waste water is nitrified and denitrified through two aerated-anoxic channels preceded by an anaerobic lagoon.
Each biological reactor has its own water supply line with its dedicated clarifier.
In addition to the biological assimilation, phosphorus is removed by simultaneous precipitation (ferric chloride).
