Welcome to FMC’s Microbial Control Business Website. We are developing our business around some long standing products and applications that are being “rediscovered” since their original inception dating from the 1940’s along with new twists and applications to meet market needs.

Peracetic acid has long had a history of acting as a “germicide” and has been steadily gaining momentum as a “green chemistry” used for direct food contact. Peracetic acid, especially FMC’s formulations, degrade simply to acetic acid, water, and oxygen without the added small chain fatty acid moieties often found in competitor’s products. This means that effluent containing minute amounts of peracetic acid or its breakdown components will have minimal impacts to microbes in treatment ponds. Additionally, during summer weather, FMC can also provide hydrogen peroxide should your treatment ponds or facilities emanate odors or become anoxic.

Successful treatment with peracetic acid within a given environment is essentially dependent on the optimization of two basic variables: concentration and contact time. System temperature will directly drive the activity or decomposition rates of peracetic acid, and thus affect contact time. FMC peracetic acid is less aggressive than other oxidizers, such as chlorine and chlorinated compounds, and thereby is not as likely to be consumed by miscellaneous organics in solution; it then will provide greater treatment against the targeted organism since more PAA is available for a longer period of time. We have demonstrated this effect in poultry chillers with simple dosing systems for FMC Spectrum™ for effective Salmonella control. The sample set data show much improved control as does the visual observations of the chiller waters.
