Abstract:
Ammonium, iron and manganese are some of the compounds found widely spread in groundwater. Such waters are usually improper for human consumption without a proper treatment. This is due to the fact that the presence of iron in the water can increase the turbidity, and global studies have shown that excessive assimilation of manganese can have adverse effects on the human body primarily affecting the nervous system. Thus, the simultaneous presence of Fe, Mn, NH4+ has led to the development of new methods for the replacement of the physicochemical removal methods of Fe and Mn by biological processes, already successfully applied in water treatment containing N-NH4+ > 1 mg / L.
