There is a high-end manufacturer, Acme Orchidarium, that makes self-contained units with RO systems, misters, cooling, etc., and they catch the runoff in a separate container and pump it out with an air conditioner condensate pump.

You understanding is apparently quite limited, making your posts absurd. Of course UV kills bacteria; they are often called "bactericidal lamps" for a reason.
Here is a quote from the abstract of a paper published almost 20 years ago:
"
Dispersal of root pathogens is a major concern in closed hydroponic cultures. To limit dispersal, ultraviolet (UV) disinfection technology has been used to remove pathogens but its effect on non-target bacterial populations is largely unknown. In this study, the circulating solution was disinfected with various UV doses (i.e., 19, 38, 59, 88 mJ cm−2) before recirculation. At the beginning of the experiment, the hydroponic solution was inoculated with Pythium aphanidermatum at 6.7±1.5 CFU mL−1. Four months later the population density of P. aphanidermatum reached 1030 CFU mL−1 in the control and 1028, 970, 610, and 521 CFU mL−1 in the solutions treated by the above UV doses. In all UV-treated solutions, significant (P<0.05) reduction of both Pythium and bacterial populations was noted."
