The overall long-term goal of this research program is to develop efficient and cost-effective waste treatment/utilization systems for the bio-resource industry, with emphasis on new technologies for nutrient recovery, the short term goals are summarized as follows:1) Biological Treatment Processes: The objectives are: 1) to develop an innovative treatment system capable of handling high strength wastewaters; 2) to study biological nutrient removal (BNR) processes, integrating both nitrogen removal and enhanced biological phosphorous removal (EBPR) processes; 3) to further develop and enhance the real-time automated monitoring and control system; 4) to investigate the difficult, but challenging, simultaneous nitrification and nitrification (SND) processes; and 5) to use the ORP signals to control or to minimize nitrification.2) Nutrient Recovery by Crystallization: The objectives will include: 1) to enhance the effectiveness and recovery rates of various crystallization processes; and 2) to study the use of other possible crystallization products, such as potassium magnesium phosphate (KMP, or K-struvite) and/or calcium phosphate, to optimize nutrient recovery.3) Solids and Sludge Management: The objectives are: 1) to study organic solids and sludge de-polymerization and nutrient solubilization; 2) to investigate sludge disinfection; 3) to explore composting processes using an in-vessel system, which has been made available to UBC.4) Microwave enhanced advanced oxidation process (MW-AOP):  The objectives include:  1) to develop new microwave enhanced wastewater treatment processes; 2) to conduct a study on the use of microwave and other oxidants for the release/recovery of nutrients from organic slurries; 3) to study the destruction of organic suspended solids in organic slurries; 4) to evaluate process efficiency, cost-effectiveness, and economic benefits of the MW-AOP; and 5) to explore potential applications of this process to other areas.
