Performance Of Carbon Aerogel/Fiber Paper As Capacitive Deionization Electrodes Under Variable Operating Conditions, Md Ashique Ahmed, Sanjay Tewari
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
The capacitive deionization has garnered renewed interested with recent modifications resulting in efficient (energy and cost) alternatives to desalinate brackish water (salt concentration less than 10 g/L). Recent research efforts, to improve the technology, have been focused mainly on electrode material development and modifications of operational parameters for optimized performance. This research is focused on performance evaluation of carbon aerogel/fiber paper as capacitive deionization electrodes under variable operating conditions. The main operational parameters that were varied are applied voltage, influent temperature and initial concentration. The highest adsorption capacity achieved in this on-going study is 4.61 mg/g at 33.5 oC with …

Undergraduate students were exposed to hands-on novel desalination laboratory experiments in an attempt to generate interest towards research in the broad field of environmental engineering and specifically in the field of water desalination. The laboratory exercises were designed to introduce desalination techniques, enhance their learning experiences, generate interest among them, and prepare them as potential researchers in laboratory settings. The hands-on experience of capacitive deionization (CDI) based laboratory experiments provided foundational and working knowledge of the CDI concept and allowed students to learn basic methodology followed in environmental laboratories to arrive at technical conclusions.
Students were given opportunity to desalinate …
