| Abstract | A novel reverse osmosis (RO) concentrate treatment process was developed; the goals of the treatment process are to remove problematic sparingly soluble salts that precipitate on the membrane surfaces and to increase the overall recovery of the RO process. The concentrate treatment process consists of three stages, including (I) antiscalant degradation, (II) salt precipitation, and (III) solid/liquid separation. Experiments were performed on a natural water sample from a karstic spring located near Marseille, France. Results were obtained for dissolved ion concentrations, precipitate particle size distribution, microfiltration flux, and orthophosphate produced. The effect of antiscalants on salt precipitation and microfiltration was evaluated, as well as the effect of antiscalant oxidation (through ozonation) on precipitation and filtration. |

| Bio | Lauren Greenlee received a B.S.E. in Chemical Engineering from the University of Michigan in 2001, graduating magna cum laude. During the subsequent year, she completed an internship in Basel, Switzerland, and taught English in a French high school. Greenlee then returned to the U.S. and worked for two years as an engineer for OmniGene Bioproducts, Inc., in Boston, MA, where she ran a laboratory of 7 bioreactors and 2 high pressure liquid chromatography (HPLC) machines. She started graduate school at The University of Texas at Austin (UT) in the Fall of 2004, in the Environmental and Water Resources Engineering Department (EWRE), where she won an NSF Graduate Research Fellowship in 2005 and completed a Master's degree in August 2006. She currently is pursuing her Ph.D. in Chemical Engineering at UT, under the supervision of Dr. Desmond Lawler (EWRE) and Dr. Benny Freeman (Chemical Engineering). |
