“…The advantages and disadvantages of several available techniques (wastewater treatment plants (WWTPs) with activated sludge treatment, WWTPs with coagulation, constructed wetlands, chlorination, membrane bioreactors, micro-, ultra-and nanofiltration, reverse osmosis, ozonation, photocatalysis, advanced oxidation processes (AOPs, for example, photocatalysis, Fenton and photo-Fenton), adsorption and activated powder) have recently been presented by Patel et al (Patel et al 2019) according to the elimination of pharmaceuticals (in terms of efficiency, toxicity of products, cost, technical operation, among others). The current reviews devoted to techniques for the reduction in pharmaceuticals from wastewaters are obtained (Shi et al 2017;Tiwari et al 2017;Stadlmair et al 2018;de Oliveira et al 2020;Femina Carolin et al 2020;Shah and Shah 2020). What should be stressed is that there is a need for a standardization of the criteria of evaluation of advanced techniques, because the report lacks important information (Fischer et al 2019).…”
