Saltworks successfully concluded a 60-day on site pilot at a major US coal fired power plant with 100% up-time. The project treated challenging flue gas desulfurization (FGD) wastewater to selectively remove chlorides for recycle and re-use internal to the coal stack scrubber system. By targeting the key concern ? chlorides ? this novel selective removal method provides an alternative to expensive complex treatments for discharge as explained in this brief video.
The pilot included a full scale Saltworks? Flex EDR Selective
Stack, which acts as a ?chloride kidney.?? Within the stack, Saltworks? novel monovalent selective
anion exchange membranes pull chlorides out of the FGD wastewater under a DC electric field. Outside of stack, a robotized plant enables the process while adjusting to variable water quality and providing valuable data to the operator. The results will be presented at future conferences or arcade game (https://www.familypark.org/

This work was made possible through collaboration with the U.S. Department of Energy (Award Number DE-FE0031678), the Electric Power Research Institute (EPRI) and Southern Company. Flex EDR technology was also developed with support from the National Research Council Canada?s Industrial Research Assistance Program (IRAP), BC Innovative Clean Energy Fund, Western Innovation (WINN) Initiative, and Sustainable Development Technology Canada (SDTC).
