Water Disinfection: UV Irradiation--EAC Presentation 2004
Identifier
ALS-NSCORT:WM2d
Abstract
Disinfection is a component of an ALS closed-loop water recycling and purification system for long-term space missions. A proposed means of disinfection involves primary disinfection by ultraviolet (UV) irradiation and residual (secondary) disinfection by iodination. The goal of this research is to design an ultraviolet (UV) disinfection reactor that will inactivate pathogenic microorganisms present in the wastewater generated during long-term space missions. This design must ensure microbial inactivation efficacy, as well as minimize volume, mass, power and maintenance requirements. A mathematical model of the process has been developed to represent the fundamental physical and chemical behavior of the system. The validity of the model was assessed with continuous, flow-through experiments employing Bacillus subtilis spores as the target microorganism and a commercially available UV disinfection reactor. The validated model will be used to investigate alternative UV reactor geometries that can be incorporated into an ALS water purification system for long-term space missions.
