This project focuses on developing next-generation affinity membranes designed to transform the way industrial wastewater is treated. Unlike conventional membranes that rely primarily on size or charge exclusion, affinity membranes are designed with specific functional groups that selectively capture and remove challenging contaminants, including metal ions and polar organic compounds. Building on lignin-based membranes, the proposed research introduces new functional layers to enhance selectivity, durability, and self-cleaning capabilities.

The membranes will be modified with specific functional groups, creating binding sites that target specific contaminants. In addition, an innovative Enzyme@MOF coating will immobilize enzymes, enabling continuous degradation of foulants such as oils and phenolics. To complement this, a thermo-responsive coating layer will be incorporated, which expands and contracts with mild temperature shifts, gently releasing deposited materials without the need for harsh chemicals. Together, these modifications aim to reduce fouling, extend membrane lifespan, and improve treatment efficiency.

The project will also scale production from lab-prepared sheets to spiral-wound elements suitable for pilot testing with live steam-assisted gravity drainage (SAGD) produced water. Through strong industrial partnerships, the research will demonstrate performance under realistic conditions, aiming for reduced chemical cleaning, lower energy use, and consistent water quality. Ultimately, this work seeks to establish a sustainable and scalable solution for water reuse in energy and remote water systems, while contributing to the advancement of functional membrane technologies for broader environmental applications.
