From the experimental results, it was observed that the removal of organic matter did not have a significant change in the presence of TiO NPs. Its removal increased by 9% in concentration of 10 mg/L of TiO NPs, and by 5% in the presence of 50 mg/L of TiO NPs. The presence of NPs did have a significant impact on ammoniacal nitrogen removal, since with the concentration of 10 mg/L, the percentage of removal decreased by 31% with respect to the system without NPs. However, it was observed that the concentration of 50 mg/L of TiO NPs favored removal, reaching a 3% increase with respect to the system without NPs. On the other hand, the removal of orthophosphates presented a direct relationship with the presence of NPs, being diminished when the concentration of TiO NPs increased . The average removal was 28%, 16% and 13% for concentrations of 0, 10 mg/L and 50 mg/L of TiO NPs respectively.
