Innova Soil Technology Ltd has developed a process to treat hydrocarbon contaminated land at costs significantly less than the current industry price and eliminate the risk of contaminant reformation and dioxin formation in the off-gases at the same time.

The process is known as Direct-heated Fast-quenched Thermal Desorption (DFTD).

The treatment facility is fully mobile allowing on-site treatment of contaminated soil with subsequent beneficial reuse of treated soil on-site. Innova's developments have concentrated on environmental considerations, energy efficiency and operational stability. The result is a treatment process that competes economically with the non-treatment options of dumping or capping while providing an efficient and safe means of permanently fixing the contaminated soil problem.

The DFTD process involves gentle heating of the hydrocarbon impacted soil to separate the contaminants into the gas phase where they are subsequently converted into water and carbon dioxide.

The conversion process is designed with a long residence time to allow complete conversion. Advanced off-gas treatment and dust collection systems have been developed to prevent contaminant reformation potential, resulting in a clean, dust-free, gaseous product stream. From a social and environmental perspective, it was essential to develop a process to treat the contaminated land problem while at the same time ensuring no negative impacts on air and water systems.

Innova's DFTD process is a cost effective, total and permanent solution to contaminated land problems.
