The Lackawanna Energy Center has three large Heat Recovery Steam Generators (HRSGs) that require demineralized water to operate in the steam and condensate systems. The facility’s demineralized water treatment system is capable of producing up to 165 gallons per minute (237,600 gallons per day) of demineralized water and includes chemical pre-treatment, two pass reverse osmosis, ultrafiltration, mixed bed manifolds, and electro-deionization.
The Lackawanna Energy Center also has a separate wastewater treatment system capable of releasing treated wastewater into the local municipal sewer system or trucking to a local wastewater treatment facility all the while keeping the main power plant facility fully operational. The wastewater treatment system recycles a majority of plant blowdown water with capacity of up to 125 gallons per minute using its own advanced containerized reverse osmosis ,ultrafiltration, and chemical treatment systems.
