title: Water disinfection by electrochemical treatment.
abstract: The electrochemical disinfection of germinated brown rice (GBR) circulating water and cooling tower water containing Legionella bacteria was investigated. Results showed the total aerobic plate counts (APC) in the treated GBR circulating water decreased significantly and the turbidity was largely improved at a pulse voltage of 1.0 kV; Legionella bacteria were also disinfected effectively at 1.0 kV. The disinfection was attributed to the synergistic effects of the oxide anode, the electric field, and the radicals formed during the electrochemical treatment. This suggests that electrochemical treatment could be applicable to the disinfection of water from other sources.
