services packaged sewage treatment systems. BMSna finds that effluent from their sewage treatment systems isquite warm, even in cold winter. The company wants to develop a technology to harness this thermal energy.Though experienced in sewage treatment systems, BMSna does not have the expertise in thermodynamics andheat transfer that is needed to analyze the available thermal energy. With a partnership between the companyand the applicant's research team at Memorial University, the objective of this Engage project is to conductthermal fluids modeling of the sewage treatment plant and come up with a conceptual system design for thespecific thermal energy recovery problem. BMSna can then use the research results for their feasibility study,prototype design and development. If successful, the thermal energy recovery and storage technology willgreatly increase the energy and environmental advantages of existing and new sewage treatment plants. Theplants will not only operate at higher efficiency and reliability, but can also provide useful heat for hot water orspace heating, which would be particularly beneficial to remote communities in the north. There are alsosignificant environmental benefits in terms of reduced pollution and less disturbance to biology systems at thetreated water discharge locations. The outcomes of this research project could make significant contribution toCanada's efforts towards sustainable development.
