Reference number : GC-2017-Q3-00537, amendment number : , agreement type : G, recipient legal name : Mohseni, Madjid (The University of British Columbia), recipient country : CA, recipient province : nan, recipient city : British Columbia|Colombie-Britannique, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Ozonation is an effective process for the degradation of colour residues that are recalcitrant to biological_x000D_
treatment in industrial effluents. A major advantage of ozonation is that, it generally does not generate any_x000D_
additional waste streams that require further treatment (for example filtration does so). The selectivity of ozone_x000D_
towards coloured and recalcitrant compounds, however, is dependent on characteristics of the effluent. This is_x000D_
especially of importance because ozone should not be used to treat organics that are easily biodegradable and_x000D_
can be removed via conventional biological processes. Hence, a thorough laboratory-scale assessment of_x000D_
efficiency of ozonation in selective removal of recalcitrant compounds from a coloured effluent is required to_x000D_
understand the advantages and limitations of this technology and to draw economic conclusions on its_x000D_
commercial-scale application._x000D_
This research is initiated by the University of British Columbia (UBC) and involves active participation of BC_x000D_
Research Inc. (BCRI). The main objective of this project is to research efficiency of ozonation for the removal_x000D_
of residual colour from an effluent produced in the mono-nitrobenzene production process._x000D_
The first and second stages of the project will involve identification of the important process parameters and_x000D_
design of a test plan to study the effect of each parameter on colour removal efficiency. The third stage will_x000D_
execute the designed test plan in a lab-scale ozone contactor, which is available in our laboratory, and_x000D_
determination of the kinetics of the oxidation process, and identification of the importance of different_x000D_
parameters. The last stage will focus on testing the optimum operating parameters in a larger scale_x000D_
flow-through ozonation unit, which is also available in our laboratory., program purpose french : Ozonation is an effective process for the degradation of colour residues that are recalcitrant to biological_x000D_
