AERC’s research
has resulted in precise methods for:
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.
Assessing potential spark discharges which could lead to
fires and/or explosions in
industries handling flammable powders and/or liquids.
