Abstract
A method and apparatus for treating a liquid (2) to inhibit growth of living organisms therein by adding to the liquid an active biocidal ingredient formed by mixing an oxidant (4) and an amine source (6), by: producing a predetermined dilution of the oxidant (4); producing a predetermined dilution of the amine source (6); synchronously metering the two dilutions into a conduit (16) 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 (16); and continuously injecting the active biocidal ingredient, as it is produced in situ in the conduit (16), directly from the conduit into the liquid being treated.
