Project Description

The goal of this project is to evaluate the potential for low-grade heat to drive water treatment via forward osmosis (FO). The project will evaluate the suitability of using FO to treat wastewater and other impaired water sources for recirculating cooling water makeup water, boiler cycle makeup water, and wet flue gas desulfurization; and to treat ash pond wastewater prior to environmental discharge.

Project Benefits

FO technology is expected to cost-effectively treat water streams with variable quality and variable flow rates to help meet rising water treatment needs at power plants. Overall, the deployment of FO systems is expected to enable reduced fresh water intake, decrease operational costs, and reduce environmental contaminant discharge from power plant wastewaters.
