Total oxidation - Denitrification

Total oxidation with denitrification

Total oxidation with denitrification

System that allows total oxidation with an added anoxic compartment, where nitrogen is eliminated through the nitrification-denitrification process, converting nitrates from the aerobic reactor into nitrogen gas under anoxic conditions.


Treatment of domestic wastewater in places where, by regulation, the elimination of nitrogen is required.
