Seminar Details
Contaminated sites with petroleum hydrocarbon adsorbed to soils and non-recoverable, non-aqueous phase liquid (NAPL) entrained in saturated soils and/or smear zones can harbour significant amounts of residual contamination. Such sites can be problematic when considering physical remediation approaches, due to desorption and dissolution of contamination from these ongoing sources. Under such conditions, more traditional, stand-alone enhanced recovery technologies and costly pump and treat systems are often rendered inefficient and ineffective.
In order to make soil-bound petroleum hydrocarbons and NAPL more readily available for various physical recovery systems to capture, a technology is required that can infiltrate soils and liberate bound hydrocarbons.
Regenesis has developed a brand new chemical oxidation based, surfactant-like, non-organic treatment technology called Petrocleanze, which produces strong detergent -like effects capable of desorbing contaminants in high residual sorbed mass areas.
Petrocleanze synergistically produces potent chemical oxidation reactions that destroy contaminants on contact in groundwater and soil. This two-part, chemical based treatment is specifically designed to dramatically enhance desorption of bound hydrocarbon mass while increasing recovery rates for enhanced physical/mechanical recovery systems, thus reducing programme times and making treatment more cost effective. Petrocleanze can be used on struggling physical systems that are stuck at asymptotic conditions or can be incorporated into new designs in order to optimise the remedial treatment.
The presentation will cover an overview of the technology as well as some discussion of case study reference sites.
