Iron oxide has been shown to retard the proliferation of bacteria


The incorporation of iron oxide catalyzed ozonation technology increases the retention of bacteria to the surface of membranes, resulting in improved remediation of water. Iron oxide catalyzed ozonation and membrane filtration will combine to improve inactivation and/or removal of bacteria. The mortality ofE. coli in the product water after treatment using the ozonation membrane filtration process with iron coated nanoparticles 4–6 nm in diameter was 99 percent. A comparison of the mortality rate of E. coli is made between various membrane treatment processes. The improved disinfection observed using the combined process is due to the catalytic decomposition of ozone at the iron oxide surface, which resulted in the formation of -OH or other radical species that inactivate the bacteria near the surface. In addition, assembled organic carbon (AOC) concentrations were reduced using the combined process, indicating that there is a reduced potential for regrowth in water treatment using the coated membranes. Due to the inactivation of E. coli and the lowering of AOC concentrations using iron oxide catalyzed ozonation technology is likely to be very effective to disinfect and control bacterial regrowth in water.
