This presentation introduces advanced treatment methodologies for the removal of heavy metals, specifically focusing on arsenic, lead, uranium and mercury. These metals, commonly encountered in Canada’s heavy industrial sectors like oil & gas and mining, present considerable environmental challenges and have high toxicity at low concentration when found in industrial waste water, groundwater aquifer and soils.

Capabilities of a novel iron based media that efficiently removes heavy metals via adsorption and precipitation processes will be presented focusing on lead, arsenic, uranium and selenium. The effectiveness of in removing toxic heavy metals to meet ultra-low discharge limits was demonstrated, showcasing its potential to significantly reduce environmental impact without altering pH levels, thus promoting cleaner industrial practices at a much lower cost than specialized ion exchange resin.

The second part will cover the ChemSorb ML, an innovative and versatile amendment for mercury removal. ChemSorb ML chemically binds various forms of mercury—including elemental, ionic, and methylmercury—achieving reductions of leachable mercury by over 99% and lowering concentrations to parts-per-trillion levels, making it an effective solution for stringent compliance requirements.

The document concludes with case studies presentation and performance data that illustrate the practical applications and benefits of these media in real-world scenarios, underscoring their effectiveness in reducing operational costs and enhancing compliance with environmental regulations.
