AERC’s research has resulted in precise methods for:

  1. Controlling the movements of particulates such as aerosols, ink toners, water droplets
    and other fine materials, by applying electrical charges to the particulates. Recent industrial
    and government clients include INCO, Ontario Hydro, Blue Circle Industries (U.K.),
    Potash Corporation of Saskatchewan, I.B.M., Nordson Corporation (U.S.A.), Toyota Motor
    Manufacturing (Canada), Ciba-Geigy (Switzerland), B.C. Hydro, Atochem (France),
    Biotech, the Ontario Ministry of the Environment and the Federal Department of Supply
    and Services for Energy, Mines and Resources Canada and Agriculture Canada, Dupont, Kirby.

  2. Assessing potential spark discharges which could lead to fires and/or explosions in
    industries handling flammable powders and/or liquids.
