Research
My research in drinking water treatment has focused in two primary areas, mechanics of coagulation/flocculation, and membranes. In the coagulation area we have developed new approaches to (1) directly measure floc size distributions, (2) characterize relative velocity fields and secondary flows in impeller-driven mixers, and (3) predict floc growth using new kinetic models that incorporate floc breakup, flow inhomogeneity and flow periodicity, and which are sensitive to process scale.
In the membrane area we have developed new methods of characterizing (and minimizing) membrane fouling by natural organic matter. Recent work includes (1) molecular dynamics simulation of the interaction of humic materials with membrane surfaces, (2) development of a low-cost laser-scanning cytometer to monitor low concentrations of particulate foulants in fresh and saline waters, (3) development of a nanostructured polysulfone adsorbent for organic fouling control, and (4) development of an aquaporin-impregnated polymer membrane
