Membrane-Treated Waste Water Project
• Petro-Canada has completed modifications at its Edmonton refinery located in the County of Strathcona, to meet new fuels legislation, modifications to process alternate crude oil feed stocks are still under construction, scheduled for completion in 2008.
• Additional quantities of water are required for the production of hydrogen and steam at the Edmonton Refinery
• Direct withdrawal from the river and waste water recycle were evaluated for the increased water requirements
• Rather than directly withdrawing additional water from the NorthSaskatchewan River, Petro-Canada worked together with City of Edmonton and Strathcona County to meet its water requirements byrecycling waste water for re-use
• There was a win-win opportunity to use membrane-treated water from the City of Edmonton’s Gold Bar Waste Water Treatment Plant
• All Costs associated with the engineering, procurement and construction of the membrane facilities and the pipeline was borne by Petro-Canada

Membrane-Treated Waste Water Project
Engineering of the Facility---the easy step• In order to produce the right quality of water from the Gold Bar Waste
Water Plant effluent, a membrane ultra-filtration treatment facility was constructed at Gold Bar
• To get the water to Petro-Canada’s refinery from Gold Bar, a new buried recycle water pipeline was built between the facilities routing through two of the City’s river parks, Gold Bar and Rundle Park and then through the Province’s Strathcona Science Park
• Construction at Gold Bar WWTP and the recycle water line were completed and placed into service by year end 2005
• Sizing of water line includes capacity for future Petro-Canada needs and also includes consideration for other users
• The system has since been expanded from 5ML/d to 15 ML/d

Langelier Saturation Index (LSI)
• Equilibrium model representation
• LSI = pH – pHs
• pHs = (9.3 + A + B) – (C + D)• Where
A= (log10 [TDS] – 1) / 10 B= -13.12 x log10 (temp oK) + 34.55 C= Log10 [Ca2+ as CaCO3] – 0.4 D= Log10 [Alkalinity as CaCO3]

Areas for improvement
• Chlorination Control – long transmission line, Surge Variability, biological re-growth in storage, fouled RO – correct level and Chlorination control
• Phosphorus – currently above specification, higher scale potential on RO andcooling water - P specific dispersants, BioP and contingency precipitation, Phosphate control at BNR
• TDS – 3X normal, -size correctly and operate with higher scaling index programme
• Langelier Saturation Index (LSI) slightly positive some CaCO3 scaling potential - pH adjustment at membranes

Membrane-Treated Waste Water Project
• This is the first major industrial application of membrane treatment technology using Municipal waste water in Canada
• The technology exists which will allow industry to make more effective environmental decisions
• The use of membrane technology is a cost effective means of meeting increased water demands and reducing the stress on the river ecosystem
• Working together with municipal governments can achieve the desired goals of all
• Petro-Canada along with their partners in the Fort Hills project have announced a similar initiative with the Alberta Capital Region Waste Water Commission to supply water for the Fort Hills Sturgeon Upgrader
