ABSTRACT:
A disinfection process is provided for preparing potable water having an unusually persistent and long lasting free available chlorine residual in order to assure safety and integrity of said water during its passage through the distribution system by which it is delivered to the consumer. The key step of this process is the generation of said unusually persistent free chlorine residual by mixing into a semi-finished water, which has already been pretreated specifically to satisfy substantially its immediate chlorine demand, dilute solution of HOCl having a pH between about 3 and about 6.
