    Published 2012-08-01
    “…The results obtained show that the removal efficiencies of organic matter in terms of BOD were achieved during Phase III (91%) and IV (82%) with phosphorus removal exceeding 40%. As for the nitrification process during Phases I and II showed rates of 0.032 and 0.024 kg.N-NH<sub>3</sub>/kg.VSS.day, this due to lower organic matter content and low BOD/TKN, while during phases III and IV these were lower: 0.015 kg.N-NH<sub>3</sub>/kg.VSS.day during Phase III and 0.020 kg.N-NH<sub>3</sub>/kg.VSS.day in Phase IV, however, was in these phases which reached the highest levels of denitrification during the anoxic phase, favored by a C/N appropriate next of 4 kg.BOD/kg.N-NO<sub>3</sub><sup>-</sup> and the presence of an easily biodegradable substrate. …”
