With the increasing world-wide demand for and pressure on water resources, new technologies and more cost effective solutions are needed for conservation and management of water resources. Under this theme and in accordance with the established on-going research program of the applicant, the principal objective of the proposed research is to develop cost effective advanced treatment technologies for micropollutant removal from water and wastewater sludge (biosolids) for water reuse and resource recovery from biosolids. The research will involve the application of advanced oxidation processes (AOP) such as UV,UV/H2O2 , and UV/O3, which produce hydroxyl radicals in-situ for the removal of model micropollutants from water and sludge, develop effective and rapid procedures based on bioassay tests to determine toxicological effects of micropollutants and their degradation products at various stages of advanced oxidative treatment. The scientific approach will involve analysis of micropollutants and their degradation products, determination of kinetics and mechanism of degradation of the micropollutants, establish the performance of various AOP pretreated sludge in anaerobic digestion, and application of the bioassay tests such as estrogenicity and mutagenicity for various effluents. A thorough economic analysis will be conducted to determine the suitable treatment option for a target compound. The proposed research will train 3 Ph D and 2 Masters students, and will share the common analytical facilities and protocols for target micropollutants developed in the laboratory of the applicant enhancing the productivity of the group. As an output of the proposed research, cost effective treatment technologies for the removal of micropollutants for water reuse and resource recovery from biosolids can be expected for potential commercialization. HQP trained in this project will be exposed to sophisticated chemical and analytical methods, kinetic modeling, and microbiological procedures.
