    Abstract:

    Understanding metal sorption to bacteria is important for developing bioremediation strategies, for determining the fate of contaminants in ground water systems, and for defining controls on microbial metabolic processes in the environment. X-ray absorption spectroscopy (XAS) has been the only technique available for quantifying and mapping metal sorption to bacteria on an individual cell scale, but the XAS approach is time consuming and expensive, and quantitative mapping of the distribution…

    Abstract:

    Peracetic acid (PAA) is an alternative disinfectant that may be effective for combined sewer overflow (CSO) disinfection, but little is known about the effect of particle size on PAA disinfection efficiency. In this work, PAA and hypochlorite were compared as disinfectants, with a focus on the effect of wastewater particles. Inactivation experiments were conducted on suspended cultures of Escherichia coli and wastewater suspended solids. Tested size fractions included particle diameters < …
