Thermal Remediation Solutions – Technologies, Applications, & Design Considerations
Traditionally, thermal remediation technologies have not been typecast by finesse or depth of range, often viewed as an expensive and onerous technology only applied to large complex sites with otherwise insurmountable contaminant mass. While thermal is still, and always will be, a great tool for source zone mass removal at heavily impacted sites, the range of technologies, treatment system designs, targeted contaminant species and remedial strategies offered by these technologies overshadow these antecedent notions from decades past. In the current marketplace, thermal remediation technologies offer unparalleled solutions across a large range of project sizes, complexity and budgetary confines.
This presentation will discuss various thermal remediation technologies, alongside the strengths and limitations inherent to each adaptation. Using several brief case studies from around the world, the range of applications and variations on thermal remediation approaches will be examined. These case studies will cover everything from surgical dry cleaner sites where single digit ppb CVOC concentrations were targeted and achieved, all the way through large scale, high temperature (350˚C or higher), industrial Sites with very high concentrations of complex co-mingled contaminant species in soil and NAPL.
Throughout the various topics and case studies presented, thermal treatment system design considerations and system optimization strategies developed from industry best practices will be discussed. The presentation will conclude with an outline of site characterization techniques, and data sets required to generate an optimal CSM that will ultimately ensure a successful thermal project implementation and optimize the overall return on remedial investment.
