What is it about?
The presence of emerging pollutants in a wastewater may affect the general efficiency of the wastewater treatment plants. Moreover, these compounds may escape traditional wastewater treatment facilities. We have shown that although caffeine and ibuprofen were almost completely removed, the degradation of metronidazole was only around 56%. It has been observed that the presence of caffeine and ibuprofen affected the nitrification, while metronidazole inhibited the denitrification process.

Why is it important?
Our work showed that the presence of caffeine, metronidazole and ibuprofen in a synthetic wastewater may result in poor removal of total carbon and nitrogen, while the combined presence of emerging pollutants in the wastewater may also deteriorate the denitrification process.
