Microwave Water Decontamination Technology

The US Army Research Office awarded SBIR Phase I and Phase II grants totaling $850,000 to CHA Corporation to develop and field-demonstrate their microwave water purification technology. This process destroys hydrocarbons, chemical and biological warfare agents in water produced from washing military vehicles at combat zones. The 2-gpm fielddemo microwave unit was constructed and transported to Camp Guernsey of the Wyoming Army National Guard and tested at both a car wash bay and a machine shop for one month in June 2005. The field demo microwave unit was then transported to the Wyoming National Guard site in Cheyenne Wyoming and operated with water produced from washing helicopters in July 2005.

After the field demonstration was complete, the microwave prototype was operated in the CHA Corporation laboratory to demonstrate the microwave ability to destroy biological agents in water. All three field demonstrations and biological tests proved successfully the effectiveness of microwave decontamination technology and produced valuable operational and performance data that has been used to modify the prototype design to develop a commercially viable microwave water decontamination system.

The US Army Research Office awarded a SBIR Phase II Plus grant of $170,000 to CHA Corporation. Enhanced Recovery, Inc. (ERI) provided $50,000 in cash and microwave equipment valued at $120,000 to CHA Corporation. Under the Army SBIR Phase II Plus program we have constructed a 20-gpm commercial demo microwave vehicle-washing system for the decontamination of combat vehicles and also for the removal of hydrocarbons from oil refinery wastewater. We installed the commercial demo microwave reactor system inside an ERI truck that houses a 915 MHz microwave generator and tested the unit at the CHA Corporation laboratory.

In January 2008 this truck housing the 20-gpm water treatment system was transported to the former Atlanta Grocery Store located at 130 Northside Dr. NW, Atlanta, Fulton County, Georgia to conduct the field-demonstration of microwave technology for ground water treatment. Dissolved gasoline constituents (benzene, toluene, ethylbenzene, and xylenes or BTEX) were removed from the site
