Removal of Antimicrobials Using Advanced Wastewater Treatment

Removal of numerous classes of pharmaceuticals from the municipal and industrial wastewater, using conventional wastewater treatment, is incomplete and several studies suggested that improvement of this situation would require the application of advanced treatment techniques [1]. This is particularly important for the treatment of industrial effluents, released from pharmaceutical industries, which can contain rather high concentrations of pharmaceuticals, including antimicrobials [2]. In this work, we evaluated membrane bioreactors (MBRs), nanofiltration, reverse osmosis and ozonation, as well as their combinations, for the removal of antimicrobials from a synthetic wastewater, which simulated highly contaminated industrial effluents. The study was performed using a mixture of four important classes of antimicrobials, including sulfonamides (SA), fluoroquinolones (FQ), macrolides (MAC) and trimethoprim (TMP). Performance of two different types of MBRs, Kubota and Zenon, was evaluated under different regimes regarding hydraulic retention time, total organic load and total nitrogen load. It was shown that the removal of SA in MBR treatment was very efficient, while the elimination of MAC, FQ, and TMP was incomplete. The removal of FQ and MAC was strongly affected by hydraulic retention time, while the impact of other parameters on the removal efficiency was not that pronounced. A mass balance of these contaminants in MBRs suggested that microbial transformation represented the main removal mechanism, while only a small percentage was eliminated from the aqueous phase by adsorption onto the sludge particles. Filtration techniques, especially reverse osmosis, proved to be very efficient for the removal of antimicrobials however they produced highly contaminated concentrate. Ozonation was found to be very effective in removing antimicrobials from both MBR effluents and RO concentrates, but further research is needed to address the issue of the ozonation products.
