PHOSter II™ is an in-situ process consisting of the controlled addition of vapor-phase nutrients to dramatically increase the microorganism population. 

This patented process, originally developed by Department of Energy scientists at the Savannah River Technology Center in Aiken, South Carolina, is a pulsed injection system that delivers a measured and predetermined combination of phosphorous, nitrogen, oxygen and a carbon-based food source, if required. 

The PHOSter II™ trailer has a programmable logic controller (PLC) to control each injection well’s pulsed injection cycle.  Because of the low flow rates (0.5 to 2.0 cfm), PHOSter II™ does not require any off-gas treatment.

The State of Florida Department of Environmental Protection Innovative Technologies Program accepted our process in 2002, and it has been successfully employed on several projects since then in Alabama, Florida, Georgia, Pennsylvania, and South Carolina. View/Download Letter
