Ozone-UV net-zero water wash station for remote emergency response healthcare units: Design, operation, and results.

ABSTRACT: Because disease pandemics can accelerate rapidly in areas with limited clean-water access, a portable greywater reuse system may be useful to provide wash water at emergency health care units. In this study, a novel fed-batch (hybrid continuous-batch flow) net-zero water (NZW), or nearly closed-loop, reuse system comprising screening, 5 μm filter, and ozone-UV advanced oxidation was designed, constructed, and tested for performance with simulated and actual human showers. Water quality was tested for compliance with US drinking water standards, total organic carbon < 0.5 mg/L, and pathogen inactivation including 12 log₁₀ virus, 10 log₁₀ protozoa, and 9 log₁₀ bacteria as has been recommended for direct potable reuse.
