System role
Pretreatment is important because oil, solids and scale-forming minerals can damage membrane performance.
How it is managed
Membranes can improve water quality and support greater reuse in some applications.
Environmental context
They also create concentrated reject streams and require energy and maintenance.
What to keep in mind
Membranes are one tool, not a universal solution for every oil sands water stream.
