Presentation conclusions indicate that: UV can be an economical option for virusinactivation despite higher UV doses;UV provides superior disinfection capabilityversus chlorine with no disinfection byproduct (DBP) issues;UV system can be designed to easily meetmore stringent future regulations;UV can be an economical option for virusinactivation despite higher UV doses;UV provides superior disinfection capabilityversus chlorine with no DBP issues; and,UV system can be designed.
