Zero Liquid Discharge System — Arizona Public Service (APS) Redhawk Power Station
The Redhawk Power Station is comprised of two 2x1 combined cycle natural gas-fired units to produce a total of 1060 MW of electrical power. Critical to the planning and permitting of this facility was the source and utilization of water and the environmental impact of the station with respect to liquid emissions. Based upon these issues, Redhawk was designed to use reclaimed municipal effluent for its process water requirements.
Based upon these issues, Redhawk was designed to use reclaimed municipal effluent from the nearby Palo Verde Nuclear Generating Station for its process water requirements. What is unique about this source of water is that it’s supplied by several neighboring City of Phoenix municipal treatment facilities with their associated seasonable variability.
