A year-long ultraviolet (UV) hydrogen peroxide (UV/H₂O₂) study was conducted using a 208- L/min (55-gpm) pilot with low-pressure and medium-pressure UV reactors. Two surface water process streams of differing organic content were used in the study, and UV doses were based on the 80 percent degradation of atrazine and 55 percent degradation of methyl tert-butyl ether (MTBE). Low and medium pressure lamp technologies also were compared. Biofilm potential was evaluated by comparing assimilable organic carbon (AOC) concentration and biofilm growth on coupons from annular reactors that simulated distribution pipe velocities. Biofilm growth on the coupons was measured by heterotrophic plate count (HPC) and adenosine triphosphate (ATP) concentration as quantified by chemi-luminescence. Biofilm potential differed between lamp technologies, but the magnitude of that difference depended on the evaluation tool utilized. Includes 7 references, table, figures.
