Abstract

The photocatalysed oxidation of phenol in waste water using advanced oxidation processes in a mass transfer efficient bubble column reactor J. M. Winterbottom*, Z. Khan, A. P. Boyes & S. Raymahasay The School of Chemical Engineering, University of Birmingham, Edgbaston, Birmingham B15 2TT, UK *E-mail: jmwinterbottom@bham.ac. uk The Cocurrent Downflow 'Contactor Reactor (CDCR) is a device of high mass transfer efficiency and the use of this efficient gas-liquid contacting device for the oxidation of aqueous solutions of phenol as a model pollutant has shown it to be a very effective technology in effecting the total degradation of phenol waste and all intermediate products. The CDCR was fitted with an internally mounted 1.0 kW UV lamp and reactions were carried out at 40-50 °C and 1 barg (202.6 kPa), with the reactor being operated in closed loop recycle mode. Complete mineralisation of 100 mg/1 phenol solutions was achieved in the CDCR
