This is an innovative technique where the soil is heated to increase volatility or reduce viscosity of organic contaminants so they may be removed via SVE or Duel / Multi-phase Extraction.
An antenna is inserted into contaminated ground and transmits radio waves causing the ground to heat, if required, to temperatures in excess of 100°C. This causes contaminants to volatilise, allowing more efficient extraction and providing the benefit of shorter treatment times.
