Based on these results, surface modification of tubular ceramic membranes with PEO-based silanes was successful in improving the rejection of bituminous foulants from the membrane surface. Finally, the decline in performance when switching to a SAGD feed, with a higher pH, total organic carbon and alkalinity, was significantly less severe for modified TiO 2 membranes compared to unmodified counterparts. This indicates that γ-Al 2O 3 is a stronger adsorbent for bituminous foulants than TiO 2, with foulants being adsorbed quickly and subsequently released during filtration and backflushing. Furthermore, flux values for γ-Al 2O 3 membranes ranged between 50 and 150 Lmh and increased over time, while flux values for TiO 2 membranes ranged between 220 and 350 Lmh and declined slightly over time. Flux recovery factors upon backflushing increased from 1.3 to 1.6. Modification of TiO 2 membranes also improved permeate flux. Modification of γ-Al 2O 3 membranes by a 30% solution of straight-chain PEO-silane increased permeate flux by factors as high as 2.9. Results indicate that the modification leads to an improvement in membrane performance. Membranes with a pore size of 10 nm and selective layers of either γ-Al 2O 3 or TiO 2 were modified based on protocols previously used on small-scale ceramic membrane disks and challenged with SAGD-produced water. To address this problem, the surfaces of commercially available multi-lumen tubular ceramic membranes were chemically modified using several charge-neutral polyethylene oxide (PEO)-based organosilanes. Bituminous clays in produced water are heavily charged and interact with the charged surfaces of ceramic membranes in a way that reduces membrane performance. Ceramic membranes are well suited for this task, but membrane fouling remains a significant barrier to their widespread application. The extraction of bitumen from oil sands using steam-assisted gravity drainage (SAGD) produces a considerable amount of oily process water that must be recycled.
