Biodegradation of diclofenac by activated sludge and membrane bioreactor-A review

D. Cherik, K. Louhab


Abstract: Diclofenac (DCF) is a pharmaceutical residue of therapeutic class of non-steroidal anti-inflammatory which is often detected in the wastewater treatment plants (influent and effluent) and surface waters. This review focuses its elimination by biodegradation with activated sludge (CAS) or bioreactor membrane (MBR) in which microorganisms plays a key role in the elimination of diclofenac and in which a lot of factors can affect the efficiency of the removal as physicochemical properties of diclofenac, sludge retention time (SRT), temperature, pH, redox conditions and sludge characteristics. The objective of this study was to describe a review of the literature by recent publications on the biodegradation of diclofenac. We inspect the performance of biodegradation using biological process technology by activated sludge and membrane bioreactor in the elimination of diclofenac.
