Description
This slide presentation outlines information on an annular reactor study on theeffectiveness of ClO<sub>2</sub> incontrolling biological growthin open-air basins. The objectives of the study included: studying the effectiveness of ClO<sub>2</sub> in controllingbiological growth in open air basins(HPC, AODC, Chlorophyll-a);compare Cl<sub>2</sub> and ClO<sub>2</sub>; and,chlorite, chlorate, bromate, disinfection byproductformation. Results of the study include: both continuous and intermittent ClO<sub>2</sub>potentially at least as effective as Cl<sub>2</sub> incontrolling biological growth;about 70 µg/L AOX and 25 µg/L TTHMdue to Cl<sub>2</sub> ; TTHM <10 µg/L for ClO<sub>2</sub>; and,bromate formation below detection limit. Also, a pilot study is discussed that studied the effect of pre-ClO<sub>2</sub> on:coagulation,settled turbidity, UV-absorbance, TOC;ozonation, UV-absorbance, residual ozone, DBP; and,filtration, particle count, headloss, turbidity.
