Dissertation title: 

Reclamation of polymer-containing produced water via electrodialysis. From process and membrane characterization to improved operation

Electrodialysis is a sound technology to achieve the objective of partially desalinating the stream reducing freshwater inputs whilst keeping the polymers in for reuse. Diverse experimental studies are presented: to evaluate the process performance for different feeds in terms of temperature and salinity; to explore conditions to preferentially remove divalent ions; and to investigate how the feed composition affects fouling of the membranes. The thesis continues with four experimental chapters exploring different configurations and operational methods to reduce fouling formation and delineate improvements for process performance. The synthesis chapter concludes with a discussion of the main findings (influence of feed composition, fouling, process performance, and water reusability), and an economic analysis of full-scale industrial implementation of the technology.
