Transforming Municipal Effluent Into High Quality Water for Industry at Canada's Largest Membrane Based Water Reuse Facility
Abstract:There is increasing demand for water in the Edmonton region as industry grows. With this growth, there is an increasing concern for water quantity and quality in the North Saskatchewan River. Alberta Environment is balancing water allocation with the need for responsible watershed protection. However, existing industries in the area including several petroleum refineries are facing increased water needs due to processing changes required by new regulations. The City of Edmonton is leading the way with solutions to some of these issues by making high quality water available from the Gold Bar Wastewater Treatment Plant (WWTP). In December 2005, Canada's largest membrane-based water reuse facility was ready to deliver water to its first industrial complex, the Air Products Hydrogen Plant feeding the Petro-Canada Refinery. The project is being phased with an initial water production capacity of 5 ML/d. The capacity will then be increased to provide up to 20 ML/d by 2008. Ultimately, the facility will be capable of producing up to 40 ML/d.
This paper describes the process that the City of Edmonton followed to develop a market for high quality reclaimed water and the subsequent needs definition, technology selection, facilities location and project execution. This process included piloting a membrane facility, a feasibility study, selecting a membrane technology, understanding design constraints and overcoming construction logistics. The arrangement called for the City to design, build, and operate the water reuse facility and for Petro-Canada to design and build a pipeline to deliver this water to its refinery. The total project was funded by Petro-Canada.
