Plummer, Jeanine D.
The goal of this project was to design an affordable, low-energy, and cost effective pretreatment process for brackish water that would subsequently be treated by reverse osmosis or electrodialysis reversal desalination to produce potable drinking water. The focus of the project was the removal of hardness, iron, manganese, and aluminum, which are primary contributors to membrane fouling. Alternatives for the removal of these constituents were tested at the bench scale. Based on results, a flow-through prototype system consisting of precipitative softening and ion exchange was constructed, and a full scale pretreatment system was designed.
