Occurrence, ecotoxicology, removal of diclofenac by adsorption on activated carbon and biodegradation and its effect on bacterial community: A review

This paper reviewed the occurrence of diclofenac in the ecosystem, its ecotoxicology and its removal. Treatment technologies were based on two methods. Firstly, the physicochemical process namely adsorption on activated carbon thanks to its economic benefits. At the other end, the second method is biological process as biodegradation by activated sludge and membrane bioreactor. In this latter process diclofenac can affect the bacterial community in sludge and influence the efficiency of treatment or biodegradation.
