Description:
Ozone and ultraviolet radiation were used as alternatives to chlorine for disinfection in several small existing community water systems. Both ozone and ultraviolet light were found to be inferior to chlorination from the standpoint of operation and maintenance requirements and maintaining disinfection in the distribution system. A disinfectant residual was found to be necessary even in the small water distribution systems studied. Neither ozone or ultraviolet provide a residual disinfectant. The main problem with chlorination in small community water systems is inadequate operation and maintenance. Inadequate operation and maintenance is a general problem of small community water systems, not limited to the disinfection aspect. Methods for improving operation and maintenance of small water systems need to be established.
