Environmental concerns: biocide use

Chlorine- and bromine-containing compounds are frequently injected into cooling water, and other water systems, to prevent fouling and pathogen build-up. The dosing of biocide required can vary with the degree of mixing of the receiving waters, temperature, levels of organic matter present, and many other factors. Dosing must therefore be balanced to provide an effective anti-fouling regime at the required point, without unwanted impacts on the wider environment. There is also, of course, an economic advantage to maintaining dosing at minimum effective levels.

Pisces staff have worked for more than 30 years on biofouling and its prevention, and on the monitoring of residual biocide concentrations in effluent water. We have considerable knowledge of the environmental effects of biocides and their impacts when released in the cooling water discharge - please contact us.
