Aeration is a well-developed technology in the cleanup and wastewater treatment industries. It is a process that promotes volatilization and biological degradation by bringing contaminated media into contact with the air. Aeration technologies include activated sludge, rotating biological contracter, trickling filters, air stripping, air sparging and bioventing (these latter three technologies are described separately). In air strippers, for example, water is allowed to cascade through a series of slats or baffles in a tower, while the air rises in a counter current flow. Other methods include blowing air through jets into the water in a tank and the use of mechanical aeration devices that propel water droplets through the air. Many other configurations are possible, including baffled tanks through which the water is forced to flow. Aeration has also been used to remove radon gas from drinking water. In this system, an air blower forces air into several treatment tanks. The radon is then stripped from the water and vented outside the treatment area. Overall radon removal efficiency ranged from 90 percent to 99.6 percent.
