To Wipe or Not to Wipe: Ensuring Equipment Cleanliness after Decontamination

At TerraTherm, our wellfield and process equipment can take a beating! Between high concentrations of hazardous chemicals, corrosive conditions, and elevated temperatures, piping and equipment generally need a bit of TLC before being put back into circulation for use at another site. When TerraTherm is operating at sites with persistent organic pollutants such as polychlorinated biphenyls (PCBs) or dioxin/furans, decontamination becomes even more difficult and even more important.  Along with typical decontamination procedures such as steam cleaning and pressure washing, washing with a non-ionizing  detergent (e.g. Simple Green) is typically necessary. Additional rinsing of equipment with specialized products such as … Continue reading

Liquid Granular Activated Carbon System Design Considerations

When developing a liquid treatment system design at TerraTherm, we keep in mind that the system will be temporary and have an overall short duration; typically 12 months or less. This means that we need to design and select a process configuration that minimizes the cost of meeting applicable discharge requirements. Cost elements taken into consideration include: To design the most cost-effective treatment system for each project, we rely on site owners and their consultants to provide detailed soil and groundwater characterization and identify the specific discharge requirements that will apply to the thermal remediation program. Liquid phase activated carbon … Continue reading

World’s Largest In Situ Thermal Desorption Project: Challenges and Solutions

TerraTherm and its In Situ Thermal Desorption (ISTD) sublicense holders have cleaned close to 50 sites, but what happens when we are presented with one that is remarkably large with more than 100,000 cubic yards (76,500 m3) of PCE and TCE rich soils to a depth of over 40 feet (12 m)? The site in particular that was presented to TerraTherm was a former aerospace manufacturing facility and had to be remediated in less than a year. Successfully completed by TerraTherm, this site in Teterboro, New Jersey is now the largest ISTD project to date. The redevelopment of this former … Continue reading
