AWWA ACE70777

This powerpoint presentation begins by providing a brief overview of the increasing occurrence of pharmaceuticals in the water supply, in particular Ciprofloxacin. Research goals are presented and include: remove the pharmaceutically activecompound, ciprofloxacin, from drinkingwater;assess the residual pharmaceuticalactivity of treated water; and,determine the effects of organicmatter on treatment efficiency. Experimental materials and methods included: Ciprofloxacin; organic matter; ozone reactor; peroxone reactor; and, MIC assay. Ozonation results are presented, along with results for MIC assay. Conclusions indicate that: Ciprofloxacin was effectively removed via liquidaddition ozonation;organic matter affects ciprofloxacin oxidation andthe formation/destruction of intermediateproducts;residual antibiotic activity was successfullymonitored using a modified MIC assay; organic matter content affects antibiotic activity; intermediate oxidation products contribute toantibiotic activity; and,considering treatment efficiency in terms ofparent compound removal is not enough. Includes figures.
