Antibiotics, release routes, and their novel removal approaches from the aquatic environments

Abstract

AbstractIntroduction: In recent years, the consumption of antibiotics has increased significantly all over the world due to health reasons related to human and animal health. The presence of these compounds even in very small amounts causes adverse effects on the environment and living organisms. The purpose of this study is to review different technologies for removing antibiotics from aquatic environments with an emphasis on new technologies.Methods: In this study, a review of library studies and articles in the Google Scholar, Science Direct, Springer, Scopus, Elsevier, and PubMed databases are used to obtain up-to-date and valid content.Findings: The results showed that membrane bioreactor systems among biological methods, despite the high cost due to the use of filtration, produce higher quality wastewater and are more effective than other biological treatment systems. Also, the investigation of biological methods showed that the efficiency of removing antibiotics varied from 40 to 95 percent. In recent years, advanced oxidation methods are a suitable option for removing antibiotics, which can completely remove antibiotics, and are also a cheap and environmentally friendly technology. In this study, several antibiotic pollutant purification technologies and their advantages and disadvantages were examined and it was shown that biological and physicochemical technologies, especially advanced oxidation processes, are capable of removing pollutants. They are medicinal. Although photo catalysts have been successfully developed for wastewater treatment on a laboratory scale, more extensive research is needed before the commercialization of these processes.
