Beschreibung
Zusammenfassung:	The present invention provides a method of treating an aqueous system for biocide control, by adding an acidified solution that includes monoalkyldithiocarbamate salt and alkyl isothiocyanate to an aqueous system. A biocide feed system is also provided that is configured to generate a reproducible level of alkyl isothiocyanate. The method and system provide effective levels of alkyl isothiocyanate for rapid biocidal activity, along with levels of monoalkyldithiocarbamate salt which can decompose to form additional alkyl isothiocyanate and provide longer-term biocidal activity. La presente invención proporciona un método para tratar un sistema acuoso para control biocida, el agregar una solución acidificada que incluye sal de monoalquilditiocarbarmato y alquil isotiocianato a un sistema acuoso. También se proporciona un sistema de alimentación biocida que se configura para generar un nivel reproducible de alquil isotiocianato. El método y el sistema proporcionan niveles efectivos de alquil isotiocianato para la actividad biocida rápida, junto con niveles de sal de monoalquilditiocarbarmato que puede descomponerse para formar alquil isotiocianato adicional y proporcionar actividad biocida a más largo plazo.
