dc.description.abstractSynergistic bactericidal performance consis tently demonstrated by combined ozone and ultraviolet irradiation treatments on poultry chiller water with bench-scale reactors has led to the detailed engineering design a nd fabrication of a mobile, se lf-contained, 16 gpm (60 L/min) prototype for testing such technology on a flow-through basis. The individual system components of this advanced oxidation process (AOP) have been integrated by means of a programmable logic controller (PLC) using ladde r logic and human-machin e interface software. Initial prototype analysis considered solids rem oval efficiency of a formulated suspension of selected bone meal ( = 1.67 g/cm 3, median diameter = 57 m) demonstrating a 57% solids removal efficiency while onsite chiller water (median diameter = 49 m) had a 29% solids reduction. Microbiological analysis indicates that bactericidal efficacy of the AOP is limited by the presence of such solids. Sy stem modifications for extended solids removal are necessary to prepare wastestreams for eff ective deactivation of suspe nded pathogens. With such preconditioning, this AOP method could readily be expanded to remediate many other processing wastewaters.
