Bactericidal activity and water purification of immobilized TiO2 photocatalyst in bean sprout cultivation

Abstract

Immobilized TiO2 photocatalysts were used to sterilize and reclaim the wastewater of bean sprout cultivation from a continuous hydro-circulation system. The photocatalysts effectively killed bacteria and degraded organic pollutants in the wastewater. Stimulation of bean sprout growth and suppression of decaying pathogens were also induced by the TiO2 photocatalytic activity.
