The goal of this proposal is to provide a novel process which converts wastewater treatment sludge into ax000D
carbonaceous sorbent, a product which can be enhanced and used to treat secondary effluent, reducingx000D
emerging contaminants before they are discharged to the environment. This waste-to-resources process wouldx000D
not only reduce the waste, but also potentially be effective for stormwater treatment and for stabilizingx000D
emerging contaminants in sediments/soils. This work will support Metro-Vancouver, a leader in progressivex000D
solutions, in promoting its sustainable region initiative on "Integrated Liquid Waste and Resourcex000D
Management" and "Integrated Solid Waste and Resource Management", as well as waste-to-resources. Thex000D
research will be carried out by Dr. Li and her Civil Engineering students at UBC. The project will involvex000D
several components: (1) Exploration of chemical activation methods with different chemicals or biomass basedx000D
on secondary sludge. (2) Optimization of operating conditions, such as pyrolysis temperature, heating time,x000D
temperature ramping rate, chemical content, catalyst type and dose. (3) Correlations between sorptionx000D
efficiency of perfluorinated compounds and physiochemical properties of the sorbents. (4) Preliminaryx000D
comparison of the sludge-based activated carbon with commercial activated carbon for the removal of a widex000D
range of contaminants from aqueous environments. It will also provide information on the economic viabilityx000D
and sustainability of producing sludge-based activated carbons on an industrial scale compared with alternativex000D
sludge reduction technologies.
