Bio-hydrogels for wastewater treatment:
Adsorption of contaminants from Montreal wastewater using bio-hydrogels
Bio-hydrogels for wastewater treatment in Montreal

Over several years, Montreal plans to invest in improving the wastewater treatment process. Presently, the city’s main wastewater treatment plant, Jean-R.-Marcotte, inefficiently removes pharmaceutical and personal care products (PPCPs) and endocrine disrupting chemicals (EDCs) from wastewater (“Montréal’s water”). Hormones such as 17-estradiol, estrone, and testosterone were found in concentrations ranging up to 9.8 ng/L in data sampled from 2006 to 2010, downstream of Montreal (Berryman et al., 2014). Notably, estrogens significantly disrupt aquatic organisms’ reproduction and general condition through feminisation, dysregulation of apoptosis, and being potentially carcinogenic (Wojnarowski et al. 2021).
We propose to improve the municipal’s discharged water treatment by designing a system that removes these compounds efficiently and sustainably. This system will feature the various beneficial properties of bio-hydrogels. Not only have such materials been proven to remove a majority of these pollutants from water, but they can also be sourced from industry byproducts and wastes (Ni & Dumont, 2017). We plan on designing a system for the Jean-R.-Marcotte wastewater treatment plant in Montreal.
