Abstract: 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.

Abstract: Se proporciona un método para medir una concentración de especies electrolíticamente activas en una solución acuosa o no acuosa para el uso en la provisión de control de la concentración de la especie en una solución de origen de la misma basada en las mediciones. En el método, una muestra que contiene una especie electrolíticamente activa se adiciona en una celda de medición que tiene un electrodo de trabajo y un electrodo auxiliar, y una corriente constante se aplica a la celda de medición mientras que los electrodos de trabajo y auxiliares están en contacto con la muestra con el monitoreo de la diferencia de voltaje a través de los electrodos hasta que se detecta un cambio en la diferencia de voltaje. Una señal de retroalimentación se genera en base a un parámetro del cambio en la diferencia de voltaje que es directamente proporcional a la cantidad de la especie electrolíticamente activa en la muestra, que se puede utilizar para el control del proceso. También se describe un aparato.

Abstract: Se describen métodos para controlar el crecimiento de bacterias en sistemas de fermentación de etanol con alternativas de antibiótico, que pueden ser biocidas no oxidantes, oxidantes estabilizados o cualquiera de las combinaciones de los mismos. Como una opción, un proceso o composición de la presente invención puede incluir uno o más péptidos antibacterianos policíclicos. Los métodos pueden proporcionar mejoras, tal como rendimientos de etanol incrementados con acarreo mínimo de biocida en los co-productos de los procesos.

Abstract: The invention provides a solid TCMTB formulation for controlling the growth of at least one microorganism. The use of a solid TCMTB formulation, as compared to a liquid, minimizes user contact and is mo re readily packaged. A solid TCMTB formulation of the invention contains TCMTB adsorbed onto a water-soluble, salt carrier matrix, with the TCMTB present in an amount effective to control the growth of at least one microorganism, preferably in an aqueous system. Other microbicides and additives may also be incorporated into a solid TCMTB formulation of the invention. In a preferred embodiment, the formulation contains both TCMTB and one or more other microbicides (e.g., methylene bisthiocyanate (MTC)) and a water-solubl e, salt carrier matrix. The TCMTB is adsorbed onto the water-soluble salt carrier matrix. The TCMTB and other microbicide are prese nt in a combined antimicrobial amount effective for the control of at least one microorganism. A solid TCMTB formulation may be used in a wide variety of biocide applications. Accordingly, the invention also relates to a method for controlling the growth of at leas t one microorganism in a liquid, preferably aqueous, system. In particular, the method controls the growth of at least one microorganism in an aqueous system by contacting an aqueous system with a solid TCMTB formulation comprising TCMTB adsorbed onto a water-soluble sal t carrier matrix in an amount effective to control the growth of at least one microorganism in the aqueous system.

Abstract: A composition for minimizing biological and/or colloidal fouling is described, which includes an anionic antiscalant and a cationically charged biocide. Further, a method of controlling fouling is described and achieved by introducing a formulation of the present invention into an aqueous system which uses a separation membrane. The compositions used in the present invention are compatible with such separation systems and preferably prevent membrane fouling.

Abstract: A method to inhibit bacteria from adhering to a submergible surface involving contacting an ionene polymer and a salt of dodecylamine to the surface. Such surfaces include ship or boat hulls, marine structures, tooth surfaces or medical implant surfaces. Compositions comprising an ionene polymer and a salt of dodecylamine can be added to aqueous systems to control biofouling. Examples of applications include industrial, recreational or sanitation water systems.

Abstract: The invention provides a solid TCMTB formulation for controlling the growth of at least one microorganism. The use of a solid TCMTB formulation, as compared to a liquid, minimizes user contact and is more readily packaged. A solid TCMTB formulation of the invention contains TCMTB adsorbed onto a watersoluble, salt carrier matrix, with the TCMTB present in an amount effective to control the growth of at least one microorganism, preferably in an aqueous system. Other microbicides and additives may also be incorporated into a solid TCMTB formulation of the invention. In a preferred embodiment, the formulation contains both TCMTB and one or more other microbicides (e.g., methylene bisthiocyanate (MTC)) and a water-soluble, salt carrier matrix.
