American Electric Power chose GE’s ABMET wastewater bioreactor system at AEP’s 1,300 MW Mountaineer coal-fired power plant in West Virginia.
The system uses a molasses-based product as a nutrient for microbes that reduce selenium, which is found in wastewater from many coal-fired power plants.
The microbes are seeded in a bed of activated carbon that acts as a growth medium to create a biofilm. The wastewater passes through the reactor and reduces the selenium in the water.
The system is expected to be operational by the end of 2011.
AEP is the third U.S. utility to use GE’s wastewater treatment process.
