Thermal remediation
In-situ thermal remediation for complex sites
Heating the treatment zone mobilizes volatile and semi-volatile contaminants for extraction, treatment, and verification against cleanup goals.
When it fits
When the source zone controls the schedule
Thermal remediation is evaluated when conventional approaches are too slow, source-zone mass is difficult to reach, or owners need stronger schedule certainty.
Doxor uses ERH for VOCs, CVOCs, BTEX, TPH, chlorobenzenes, and vinyl chloride where heating improves recovery across the target interval.
Design controls
Heat, extraction, and verification work together
Design starts with the conceptual site model: contaminant distribution, lithology, groundwater, preferential pathways, utilities, structures, and access limits.
The team then defines treatment volume, temperature, electrodes, vapor extraction, electrical safety, monitoring, sampling, and optimization triggers.
Brazil experience
Built for active and urban sites
Doxor technical records cover more than 15 years of ERH work in Brazil, including sensitive public sites, industrial facilities, and deep chlorinated solvent treatment.
Early review of access, vapor risk, electrical safety, receptors, and depth reduces redesign and improves project confidence.
