Abstract

Process for removing nitrogenous compounds, in particular nitrates, and for remineralizing water with a low mineral content, characterized in that the removal of the nitrogenous compounds and at least partial remineralization of the untreated water are carried out simultaneously by biological treatment, in the same reactor. The denitrified and remineralized water is then subjected to coagulation, flocculation and clarification treatments.
