Abstract
|
Adavanced
Oxidation Processes (AOPs) represent a group of promising technologies for
the degradation of Refractory Chemical Pollutants as, for example,
Chlorophenols (CPs) compounds of a special interest because of their high
toxicity and low biodegradability. Authors describe the application of AOPs
treatments on an actual case study consisting in the design of an
Industrial-scale refinery effluent treatment & recovery plant.
The water portion generated which was not recycled, had to be discharged into the ocean with strict limits. For this purpose, two different AOPs treatments were studied at lab scale: the combination of hydrogen peroxide (H2O2) with a liquid catalyst and the adoption of H2O2 in combination with UV light. Results revealed that the system resulting from the combination of H2O2 with a liquid catalyst into a specific H2O2/catalyst range allowed a higher phenol degradation kinetics than the treatment based on hydrogen peroxides coupled with UV light. Once the AOP treatment was optimized on a laboratory scale, the design for its adoption on an industrial scale was conducted and the system was integrated as a tertiary treatment in a wastewater system including Coalescent Plate Interceptors (CPI) and Flotation as Deoiling treatment and a Membrane Bioreactor (MBR) Oxidation system as a biological treatment. |
