Abstract

Fremgangsmåter for overvåking av resterende behandlingsmiddel i behandlet vann der fluorosens intensitet i vannet ved minst to fiorskjellige doseringer av behandlingsmiddel tagget eller tracet med fluorescente tracere bhr korrelert med resterende konsentrasjon av behandlingsmiddel. Den fluorescente responsen ved fiorskjellige doseringer av behandlingsmiddel blir også anvendt til automatisk å bestemme en optimal dose av behandlingsmiddel på en kontinuerlig basis og å kontrollere dose av behandlingsmiddel tilsvarende.Methods for monitoring residual treatment agent in treated water where the intensity of fluorosis in the water at at least two different doses of treatment agent tagged or traced with fluorescent tracer bhr correlated with residual treatment agent concentration. The fluorescent response at various doses of treatment agent is also used to automatically determine an optimal dose of treatment agent on a continuous basis and to control the dose of treatment agent accordingly.
