Development Of Hybrid Ion Exchange Processes Driven By Carbon Dioxide (Hix-Co2), Hang Dong

Theses and Dissertations

Freshwater scarcity is severely faced by humans even though our planet is full of water,being more than 97% of the water is salty water such as seawater or brackish water. Andsome of the brackish water is impaired by various of contaminants, such as nitra

Integrating Tunable Anion Exchange With Reverse Osmosis For Enhanced Recovery During Inland Brackish Water Desalination, Ryan Casey Smith

Theses and Dissertations

For inland desalination plants, managing and discarding produced brine leftover from the production of pure drinking water can be a significant operating cost. By increasing the recovery of the desalination process, brine volume and disposal costs will be reduced. Achieving high recovery is not immediately possible as when the recovery is increased, there is a higher potential for the precipitation of calcium sulfate which, for reverse osmosis (RO) processes, can foul and damage the RO membrane. Ion exchange may be used as a pretreatment method to selectively remove and replace sulfate by chloride which does not pose any threat to ...
