| Abstract | The performance of a small-scale water disinfection system which was installed in a hospital in Mexico City in August 1989 was evaluated. Prior to installation of this equipment, tests showed that residual chlorine concentrations were lower than the national standard in 89 per cent of the samples (n=206), while 35 per cent (n=61) had unaccepatle levels of total coliforms and 15 per cent (n=34) were contaminated by faecal coliforms. The installed disinfection system was based on MOGGOD (mixed oxidant gases generated on demand) cells which produced a mixture of oxygen, ozone and chlorine gas from the in situ electrolysis of sodium chloride (table salt). The equipment cost about US$ 1,270 and around US$ 6 was required per month for the purchase of distilled water and sodium chloride. After installation residual chlorine concentrations were found to be adequate and no coliform bacteria were detected. |
