Microwave-Assisted Degradation of Organic Contaminants and Regeneration of Granular Activated Carbon in Water Treatment

This project explores microwave-assisted thermal treatment as a sustainable method to both degrade organic contaminants and regenerate granular activated carbon (GAC) used in water treatment. The goal is to determine whether high-power microwaves can desorb and break down pollutants from spent GAC while preserving its structure and extending its adsorptive life.

A range of micropollutants including pharmaceuticals, phenols, dyes, and pesticides, will be tested on coal, coconut, and wood-based GAC under controlled 2.45 GHz microwave exposure. By promoting desorption and thermal transformation, this approach could reduce reliance on chemical regeneration or full mineralization while enabling multiple reuse cycles of GAC.

AGP Dynamic Solutions Inc., a Canadian leader in industrial microwave systems, is the industry partner. With expertise in high-power microwave technology, AGP is evaluating how its systems can support on-site GAC regeneration, cutting operational costs and carbon waste for water utilities and industries.

Led by an intern with advanced research training in water filtration, the project will use advanced analytical tools to assess regeneration efficiency. The outcomes could drive scalable, innovative solutions that lower waste, support cleaner water, and align with circular economy and public health goals.
