Hot air tools used to clean up diesel and gasoline contaminated soil
Assembly Supplies Company works with Brady Environmental to clean up diesel and gasoline contaminated soil on the shores of Togiak Bay, Alaska.
The shores of Togiak Bay Alaska suffered an enormous environmental catastrophe when diesel and gasoline was spilled, contaminating the pristine environment. Years after significant efforts had been made to clean up the spill site. There were still looming issues of contaminated soil. One remote fish processing facility decided to cut their losses and sell their establishment. In order to proceed however, the fishery needed to come up with $12 million in clean-up costs. Not only were the costs overwhelming but so were the challenges that go into cleaning a remote 5-acre site. To make matters even more difficult, there were no legitimate roadways and all equipment had to be either flown in or shipped by barge.
Assembly Supplies Company worked with Brady Environmental and provided the necessary equipment to power a patented system comprised of Leister hot-air tools and soil ovens. "Evaporative Desorption Thermal Soil Treatment", is a patented and innovative system that uses hot air tools and airflow to evaporate contaminated soil. This innovative solution dramatically helped the environment by cleaning the contaminated soil while simultaneously saving the owners of the fish-processing facility $8 million dollars.
How hot air tools helped save the environment
The old way to clean up contaminated soil utilized a heating system with an open flame to boil off the water. In the process of boiling the water, harmful chemicals and contaminates were released into the air. It's necessary that this contaminated air be cleansed before it is released back into the environment. The costs for undergoing this outdated process in a remote fishery amounted to $12 million. By working with Assembly Supply Company and developing a new and better soil treatment system using hot air tools and soil ovens to evaporate the contaminated soil, the price tag for the project came down by two thirds of the original price.
Finding the right hot air tools
Searching for the right tools Brady, from Brady Environmental met with the owner of Assembly Supplies Company to discuss how hot air tools could be used to clean up the contaminates. Brady presented the solution of the Evaporative Desorption Thermal Soil Treatment System, but needed the right tools that could operate continuously for months on end. Assembly Supplies Company worked with Brady to get him twelve of the Leister's most powerful devices, the LE 40,000 heater, with 39 kWs to pump hot air into three soil ovens.
The Leister LE 40,000 heaters regulate the heat output by monitoring the system to ensure the temperature hovers around 1,000 degrees Fahrenheit. Heat regulation is crucial for more than one reason. First, if the temperature were to rise over 1,300 degrees Fahrenheit, it would produce emissions that they were trying to avoid by creating this system. Second, the tools would need to be running without stopping for months on end
