Since 1997, US Ecology's Airport Services Division has tailored our services to assist our aviation customers in managing their glycol-contaminated storm water programs. Using the latest in waste water technologies, collection methods and an extensive transportation and marketing network, US Ecology airport services has helped ensure our customers' continued compliance to their local, state and federal discharge regulations and permits.
The glycol collected on site will be shipped via rail back to the Glycol Processing Unit at the US Ecology Romulus facility located in Romulus, MI. The material is then pretreated and processed through a high efficiency evaporator to separate water from glycol (to approximately 60-70% glycol concentration). The concentrated glycol is then further processed through a vacuum distillation column to produce a 99+% pure product. The recycled product is sold to established outlet markets for reuse as an industrial grade Propylene Glycol.
US Ecology also won a contract to supply operators to run the anaerobic waste water treatment plant as well as the recycling plant at the Northern Kentucky International Airport (CVG) in Cincinnati, OH. Two US Ecology technicians will be on-site full time to oversee the daily operation of the plants. With the addition of these two locations, US Ecology now has fixed based operations at six major airports across the United States.
