Indianapolis Power & Light Co.’s Petersburg Generating Station will upgrade its wastewater treatment equipment.

GE will provide its brine concentration (evaporation) technology to treat flue gas desulfurization (FGD) wastewater discharge. The new system will allow IPL to meet EPA's National Pollutant Discharge Elimination System (NPDES) permit requirements. The power plant’s wastewater will be recycled into clean water for reuse in the facility.

The 1,760-MW coal-fired power plant also will add scrubber blowdown equipment, softening clarifiers, thermal brine concentrators and associated auxiliary equipment. The new treatment system is expected to begin operation in 2017.
