Precipitation

  • Treatment of roof runoff from zinc and copper roofs
  • Removal of heavy metals from street runoff

Copper and zinc are heavy metals that can be released into the environment through rain water running off roof gutters.

Areas where vehicles are parked, as well as heavily used roads and streets, are also a source of further hazardous substances such as cadmium, lead or nickel due to exhaust gases or tyre wear. GEH® is the ideal adsorption material, in order to remove these specific metals and so protect our natural world.
