In-situ chemical oxidation

The chemicals (permanganates, peroxides etc.) required for the execution of ISCO are prepared above ground and fed into the groundwater by injecting it through a GCW. The required quantities should be determined by means of laboratory tests beforehand. To mix in hydrogen peroxide in moderate concentrations will stimulate the aerobic biological degradation. The radial-symmetric circulation fields permit more homogenous and more effective dispersion of chemicals in the subsoil than other hydraulic processing techniques.
