UV disinfection: To pilot or not to pilot?

Honolulu evaluates and compares established wastewater treatment systems with newer technology. The effectiveness of low- and high-intensity ultraviolet lamp technology to disinfect unfiltered secondary effluent is evaluated in this pilot-scale study. One goal was to determine the true UV dose required to disinfect indicator bacteria in unfiltered secondary effluent using a collimated beam unit. Another focus was to correlate the effectiveness of all three UV systems while verifying water quality for each.
