Rapid Disinfection of Water With High Concentrations of Hypochlorite
This article discusses five steps that have been mechanized so that it is possible to measure bacterial kills by high chlorine concentrations over intervals as short as 0.1 sec. The equipment and process are also readily adapted for the study of other disinfecting systems, enzyme reaction rates, and a variety of biochemical and physiologic processes involving two or more reacting materials. The process consists of the following steps: a stock suspension of test bacteria is run, at a controlled rate, through a tube of fixed and known volume; the hypochlorite solution mixes with the bacterial suspension as it enters the calibrated flow tube; disinfection reactions occur during flow residence within the tube; the disinfected suspension discharges into a collection vessel containing dilution water and a large excess of sodium thiosulfate; and, samples taken at the beginning and end of the flow‐contact system reflect chemical and bacteriologic changes.
