Abstract
A method and apparatus for treating a liquid to inhibit growth of living organisms therein by adding to the liquid an active biocidal ingredient formed by mixing an oxidant and an amine source, by: producing a predetermined dilution of the oxidant; producing a predetermined dilution of the amine source; synchronously metering the two dilutions into a conduit to continuously mix therein according to a predetermined ratio to produce the active biocidal ingredient having high reproducibility, stability and efficacy in situ in the conduit; and continuously injecting the active biocidal ingredient, as it is produced in situ in the conduit, directly from the conduit into the liquid being treated.
