Membrane fouling can be reduced through shear stress generated by cross-flow at the membrane surface. Previous work has shown that presence of ozone can reduce membrane fouling. In this work, the effect of ozonation and cross-flow on both membrane fo

The Flint River is a variable water source and thus a challenge to treat; oversights and missteps combined with inherent chemical conditions set the stage for the historic water crisis in Flint, Mich.

The effect of pH, inlet ozone injection rate, initial bromide concentration, membrane coating, hydroxyl radical scavenger, and membrane molecular weight cut off (MWCO) on the formation of bromate in a hybrid membrane filtration–ozonation reactor tr

This article reports for the first time that fullerene (nC60) can form chlorinated disinfection by-products in aqueous systems at ambient temperature. The ability of nC60 to form colloidal suspensions in aqueous media increases the chance that these

The removal of the disinfection byproducts (DBPs) precursors, antibiotics dicloxacilline and ceftazidime by hybrid ozonation membrane filtration (HOMF) has been studied in three surface waters (Lake Huron, Lake Lansing and Huron River). This study de

The effect of the nature of the membrane surface, the presence of hydroxyl radical scavengers, and temperature, on bromate formation in a hybrid ozonation membrane filtration reactor was studied. The presence of tertiary butyl alcohol, a hydroxyl rad

Ceramic ultrafiltration membranes were coated with the hydrated MnO2 using a novel layer-by-layer (LbL) technique. Ozonation of MnCl2 was used to prepare the MnO2 nanoparticles used in the LbL procedure. The coated membranes were then sintered in air

Tubular ceramic membranes (molecular weight cut-off, 5 kDa) were coated with manganese oxide nanoparticles. Atomic force microscopy imaging of the coated membranes showed no statistically significant change in the surface roughness or maximum height
