Researchers at UPEI are exploring the use of sawdust for wastewater treatment, aiming to tackle ‘forever chemicals’ such as PFAS in the future. The initiative involves converting sawdust sourced from local mills in Prince Edward Island into activated carbon, a common component in household water filtration systems. Yulin Hu, an engineering assistant professor at UPEI, likened the process to a sponge, trapping contaminants within its porous structure for removal from water.
Initial tests have been conducted using synthetic dyes, a prevalent water pollutant in the textile industry. The next phase involves evaluating its efficacy on actual wastewater from local industries. While its performance against PFAS-contaminated water has yet to be determined, there is optimism that this method could aid Islanders grappling with water contamination issues.
A report from the federal government highlights the harmful effects of PFAS exposure on various bodily systems. Hu emphasized the significance of addressing PFAS contamination in drinking water for affected communities in P.E.I. The project, spearheaded by Milad Jalilian, a UPEI PhD student, reflects a commitment to environmental stewardship and community well-being.
Jalilian’s transition from a petroleum engineering background to environmental research was influenced by witnessing oil spills during offshore work. His dedication to mitigating water pollution underscores the project’s broader impact on society and the environment. The ultimate goal is to develop a versatile filtration system applicable for both household and industrial use.
In addition to producing activated carbon, researchers are exploring the transformation of sawdust into biochar, a beneficial material for agricultural practices. Hu envisions farmers utilizing biochar to improve soil water retention. This innovative approach not only addresses water treatment challenges but also offers sustainable solutions for multiple sectors.
