The effect of treatment sequence in combined photocatalytic-biodegradation of phenol

As phenol is a hazardous pollutant even at low concentration, it needs to be removed from the wastewater. This study focusing on the degradation of phenol by photocatalytic treatment where the effect of initial concentration and catalyst loading was investigated and also the effect of combine treatment sequence of phenol. One of the main objectives of this study is to investigate the effect of treatment sequence of combined photocatalytic- biodegradation on phenol degradation. Degradation of phenol was studied using two different combine treatment sequences which are biodegradationphotocatalytic and photocatalytic-biodegradation.
