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 Dual / 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.
ISRFH won the Brownfield Briefing (BB) awards in 2009 for the most innovative remediation method and again in 2010 for the best use of a combination of remediation techniques. the technology was also featured in CL:AIRE technology bulleting TPD 28.
