Abstract Scope |
Produced water, a waste product of the oil extraction process, is commonly disposed in underground injection wells due to its high oil and salt concentrations. The filtration and recycling of produced water has the potential to dramatically impact the environment by not only reducing the need for disposal wells, but by enhancing water security around the world.
With their robust thermal and chemical stability as well as long lifespans, ceramic membranes are ideal for environmental waste applications such as produced water. A novel low-cost environmentally-friendly porous ceramic composite membrane has been developed using geopolymer with zeolite filler. The composition of the membrane was optimized for microstructure and filtration performance, while porosity was studied using scanning electron microscopy, mercury intrusion porosimetry, and MicroCT. Results from filtration studies confirmed the removal of particulate and dissolved impurities from produced water. Strategies for improving filter design and performance will be discussed. |
