Researchers from the University of Prince Edward Island (UPEI) are exploring the use of sawdust for wastewater treatment, aiming to target “forever chemicals” such as PFAS in the future. By converting sawdust sourced from local mills on Prince Edward Island into activated carbon, similar to that in household water filters, the team led by Yulin Hu, an assistant professor of engineering at UPEI, is effectively creating a sponge-like material that traps contaminants from water.
Initial tests have shown promising results against synthetic dyes, a common water pollutant in the textile industry. The next phase involves testing the technology on real wastewater from various industries on the island. While the efficacy against PFAS-contaminated water has yet to be confirmed, there is optimism that this approach could aid Islanders grappling with contaminated drinking water.
PFAS exposure is associated with adverse health effects according to a report from the federal government, impacting organs such as the liver, kidneys, immune, reproductive, and nervous systems. The potential application of this technology in communities affected by PFAS contamination underscores the importance of clean drinking water.
Milad Jalilian, a PhD student at UPEI, emphasized the shared responsibility in safeguarding water quality, drawing from his past experience as a petroleum engineer witnessing oil spills. His transition into environmental research reflects a commitment to community and environmental well-being.
The ultimate goal of the project is to develop a filtration system suitable for both household and industrial use. Additionally, the team is exploring the conversion of sawdust into biochar, a product that could benefit farmers by enhancing soil water retention capabilities.
