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

What’s the Temperature? Thermal Modeling and its Importance in Thermal Remediation

What is a model? A beautiful person who struts down a run way, a scaled down sculpture of the Empire State Building, or a series of equations that describe some phenomenon? Did you guess all of the above? Gold star! Models come in many different shapes and sizes. In the environmental consulting and remediation industry, the word “model” often refers to a numerical model. Numerical models are tools that we use to better understand a system. They can be used to make predictions and to test hypotheses. The thermal models that we customize and construct in house at TerraTherm are … 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

TerraTherm Enjoys Rapid Growth as ISTR Gains Industry Acceptance

Recently, TerraTherm was featured in Environmental Business Journal’s 2015 Remediation issue. The article, “TerraTherm Enjoys Rapid Growth as ISTR Gains Industry Acceptance,” features an interview with TerraTherm co-founder, CEO and President, John Bierschenk. TerraTherm has grown its revenue nearly three-fold to greater than $30 million over the prior three years. By diversifying its project portfolios and building a strong backlog of upcoming projects, our strong growth rate will continue in 2015, reflecting an expanding demand for quick, predictable and cost effective remediation solutions. Mr. Bierschenk cites overall industry acceptance of ISTR technologies since they first emerged from the enhanced oil recovery … Continue reading

Effective Safety Management of ISTR Sites

There are numerous health and safety challenges that can be found on an In Situ Thermal Remediation (ISTR) site.  From performing health risk assessments for hazardous chemicals to identifying and correcting on-site physical hazards or working with and managing a variety of subcontractors, there is an extensive list of safety and regulatory concerns that need to be addressed. Managing these concerns can often appear to be a daunting task, but with a practical, risk-based safety management approach, ISTR can be performed safely, as well as effectively. At TerraTherm, our strong safety management system begins with a commitment to safe work … Continue reading

TerraTherm’s Continued Growth in 2014: A Year in Review

The application of In Situ Thermal Remediation (ISTR) for treatment of subsurface contaminants continued to grow in 2014. With the emergence of ISTR as a proven source area remediation tool and with the number of projects increasing rapidly worldwide, comes the rumbling of a paradigm shift in the remediation industry. Only 20 years ago, it would have seemed impossible to remediate the types of sites that are currently being treated with ISTR to the same degree that we are now consistently doing. Throughout our nearly 15 years of operation, TerraTherm has been a solution for clients who wish to quickly, … Continue reading

Webinar: In-Pile Thermal Desorption® (IPTD®) for Treatment of POPs-Contaminated Soil and Sediment

In case you missed our last installment of “Inside In Situ Thermal Remediation”, TerraTherm’s informational webinar series, you can find a recorded version here: “In-Pile Thermal Desorption® (IPTD®) for Treatment of POPs-Contaminated Soil and Sediment” Presented by TerraTherm’s Co-Founder, Chairman and Chief Scientist, Ralph S. Baker, Ph.D., this webinar was recorded on September 11th, 2014. Description: Soil or sediment contaminated with Persistent Organic Pollutants (POPs) including PCBs, PAHs, organohaloginated pesticides, Dioxins and Furans and other recalcitrant organics, as well as mercury can be treated effectively at elevated temperatures. By contrast, conventional treatment typically requires excavation and transportation of the soil … Continue reading

Thermal Treatment of Fractured Rock – How is it Different?

Fractured rock sites are different – often it is difficult even to determine how deep the Non-Aqueous Phase Liquid (NAPL) has gone, and to define what we refer to as the “source area”. Some sites have NAPL in the fractures, and some have most of the mass trapped in the matrix, into which it has diffused over decades. This blog post discusses the two main challenges: How to decide on the thermal treatment volume without making the problem worse. How to design and implement an effective and safe thermal system. For any aggressive source treatment to be cost-effective, it is … Continue reading
