This slide presentation outlines a joint research effort between the University of Alberta and PWN to study the ultraviolet (UV) inactivation of protozoa, viruses and bacterial spores. Topics covered include: UV disinfection collimated beam and small scale pilot experiments; UV inactivation of micro-organisms with 120 mJ/cm2, PWN pilot plant experiments; in vivo reactivation of G. muris after medium pressure UV; surface water treatment based on breakpoint chlorination and GAC filtration; emerging organic contaminants; atrazine degradation and bromate formation in synthetic water; NDMA degradation by UV photolysis; relative degradation by UV photolysis and UV/H2O2 oxidation in pretreated IJssel lake water; bromacil and atrazine degradation by UV photolysis, UV pilot plant experiments; bromacil degradation by UV/H2O2 treatment combined effect UV photolysis and hydroxyl radical oxidation; atrazine degradation by UV/H2O2 treatment combined effect UV photolysis and hydroxyl radical oxidation; UV and H2O2 dose required for 80% atrazine destruction, collimated beam experiments; atrazine degradation by UV/H2O2 treatment pilot plant experiments; emerging organic contaminants; microcystine degradation by UV photolysis and UV/H2O2 oxidation; pharmaceutical degradation by UV/H2O2 oxidation UV dose 600 mJ/cm2, H2O2 dose 6 g/m3; and, conclusions on UV/H2O2 treatment for organic contaminant control and UV disinfection and UV/H2O2 treatment.
