The PlasmaWhirl turbine integrates aeration, biosolids gasification and UV disinfection. The process utilizes dual plasma systems. First, an electro-plasma system gasifies unpressed sludge (3% solids), which is steam reformed in a second plasma torch—the ArcWhirl—which is then internally cooled with wastewater effluent and irradiated with UV light from the carbon arc. The hydrogen and steam plasma are injected into the lean combustion chamber and the oxygenated exhaust is used to aerate wastewater influent.
