Abstract: Se describe un método y composición para controlar el crecimiento de materiales de ensuciamiento, tal como incrustación, en sistemas acuosos utilizando un polímero marcado (fluorescente). El polímero marcado puede ser un polímero fluorescente que tiene por lo menos una unidad monomérica fluorescente derivada de un fluoróforo que tiene por lo menos un extremo terminal que comprende un grupo olefínico. El método para controlar el crecimiento de por lo menos un material de ensuciamiento en un sistema acuoso puede incluir las etapas de adicionar el polímero marcado al sistema acuoso que es tratado, inspeccionar fluorométricamente la concentración del polímero marcado y ajustar, como sea necesario, la concentración del polímero marcado y proporcionalmente el compuesto o compuestos para tratamiento de agua utilizados efectivos para controlar el crecimiento de por lo menos un material de ensuciamiento del sistema acuoso. El ajuste de pH antes de la determinación de la señal de fluorescencia se puede emplear para incrementar la sensibilidad de fluoróforo y minimizar la interferencia de fondo.

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: 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 of controlling an exothermic or endothermic chemical reaction is provided. The method involves measuring a temperature of a first reactant flowing at a first flow rate, contacting the first reactant with a second reactant flowing at a second flow rate to form a reaction product, measuring the temperature of the reaction product, and determining the temperature difference between the temperature of the first reactant and the temperature of the reaction product. The method can further involve adjusting the flow rate of at least one of the first reactant and the second reactant, or shutting down flow, based on the temperature difference. An apparatus to carry out the method is also provided. The method and apparatus can be useful in controlling many different reactions, including the reaction of sodium hypochlorite and ammonia to form monochloramine.

Abstract: A method is provided for measuring an electrolytically-active species concentration in an aqueous or non-aqueous solution for use in providing control of the concentration of the species in a source solution thereof based on the measurements. In the method, a sample containing an electrolytically-active species is added into a measurement cell that has a working electrode and an auxiliary electrode, and a constant current is applied to the measurement cell while the working and auxiliary electrodes are in contact with the sample with monitoring of voltage difference across the electrodes until a change in the voltage difference is detected. A feedback signal is generated based on a parameter of the change in the voltage difference that is directly proportional to the amount of the electrolytically-active species in the sample, which can be used for process control. An apparatus is also described.

Abstract: A method and composition is described for controlling the growth of fouling materials, such as scale, in aqueous systems using a tagged (fluorescent) polymer. The tagged polymer can be a fluorescent polymer which has at least one fluorescent monomelic unit derived from a fluorophore which has at least one terminal end comprising an olefinic group. The method of controlling the growth of at least one fouling material in an aqueous system can include the steps of adding the tagged polymer to the aqueous system to be treated, fluorometrically monitoring the concentration of the tagged polymer, and adjusting, as needed, the concentration of the tagged polymer and proportionally used water treatment compound or compounds effective to control the growth of at least one fouling material in the aqueous system. The adjustment of pH before determination of the fluorescence signal can be employed to increase sensitivity of the fluorophore and minimize background interference.
