ABSTRACT This work carried out an integrative review of scientific articles indexed between 2007 and 2017 in different databases on treatment and reuse of effluents from the antibiotic industry. Thirty-one articles were found and only four addressed effluent reuse, and one used a full-scale treatment system. Most of these studies were conducted in Asia, with emphasis on China. In Brazil, which is one of the largest producers and consumers of drugs in the world, this type of research is still incipient. The most commonly found processes were oxidative advanced processes that showed greater efficiency in removing antibiotics, but may generate by-products, which might pose an even greater risk depending on the substance formed. Biological processes must first be acclimated to antibiotics in order not to be impacted, however, the release of these resistant microorganisms into the water bodies also presents an environmental risk. Biological integrated membrane systems were also very efficient, but attention should be given to the risk in the final destination of these membranes that were able to retain those compounds. Overall, further studies on this approach are needed to reduce the risks of developing multi-resistant microorganisms in the environment.
