how to destroy biocide

[lenavt]

hi, could anyone suggest how to treat biocides ( 2-methyl-4-isothiazolin-3-one is of a particular interest) before they hit bioplant? expected influent concentration is 0.5-1 ppm. i heard something about sodium bisulfite but cannot understand the mechanism. i will appreciate very much any input.

2-methyl-4-isothiazolin-3-one is a non-persistent antimicrobial that is inherently biodegradable and degrades rapidly. You probably do not have anything to worry about if Iso enters your wastewater treatment plant.

Try to find the paper "THE ENVIRONMENTAL FATE OF ISOTHIAZOLONE BIOCIDES" by Rohm and Haas.
