dc.description.abstract | Disinfection needs to meet the personal hygiene requirements of interplanetary travel community in space vehicles is currently accomplished through the use of pre-packaged, disposable, wetted wipes, which represent an appreciable carry-along mass and disposal burden. There is a stated need to develop a system that could use onboard utilities to create on demand disinfectants thereby reducing the astronaut�s dependence on earth-based supplies and further eliminating storage and disposable problems. Within this context, we are developing an in-situ approach to electrochemically generate hydrogen peroxide disinfectant utilizing onboard life support supplies (Air/Water) to eliminate many of the surface contaminants present in closed living systems. As discussed within our 2018 paper we have demonstrated the potential to produce up to 1 w/w% peroxide with DI water and oxygen utilizing our optimized system. This paper will build upon that work and discuss the results from our zero-gravity flight test and system scale-up activities. Furthermore, the system has been shown to be amenable to utilize various water streams (DI, RO, and Tap water) with or without I or Ag additions as well as air or pure oxygen supplies. Finally, we have scaled the system to produce up to 6 L per day of 1 w/w% peroxide and are working to increase the output concentration up to 6 w/w% peroxide. The peroxide generation system offers a more economical and practical alternative, with the disinfectant solution being generated on demand and in-situ; and applied to reusable cloths, reducing both the carried and disposed mass associated with the disinfection process. The peroxide generation system demonstrates a strong potential to address a critical need of disinfection within ISS and will also be able to address Earth-based needs in various settings such as hospitals, restaurants, movie theatres, among many others.
