    摘要: A process for monitoring and controlling an aqueous system. At least one performance parameter relating to conditions within the aqueous system is selected. A value of the at least one performance parameter is measured to serve as a baseline value. A capacity of the aqueous system is determined and flow rates of water into and out of the system are measured and monitored. The value of the at least one performance parameter is measured and compared the value to the baseline for the performance parameter. Flow rates of water into and out of the system are factored in. At least one controllable variable within the aqueous system is altered based upon a deviation of the value of the at least one performance parameter from the baseline value.

    摘要: A method of detecting microbiological fouling in an aqueous system. The method includes determining a baseline corrosion rate. A corrosion rate is continuously monitored. A change in the corrosion rate is measured. A maximum corrosion rate is measured. A baseline fouling factor is determined by measuring and monitoring parameters of a fluid in the aqueous system. An increase in fouling factor over the baseline is determined. A change in the corrosion rate is integrated with respect to time over an interval of from a time of the determination of the baseline corrosion rate to a time that the maximum corrosion rate occurs. A change in the fouling factor is integrated with respect to time over an interval from a time of the determination of the baseline fouling factor to a time of the determination of the increase in fouling factor. The fouling factor and the corrosion rate are compared to determine if the fouling is microbiological.

    摘要: This invention relates to an automated process for efficiently treating an aqueous system with chlorine dioxide. The process results in high efficiency yields of chlorine dioxide on a continuous basis by minimizing the waste of precursor chemicals. Additionally, the process creates less environmental stress because the formation of unwanted by-products is minimized. The level of chlorine dioxide in the aqueous system treated and other parameters of the process are monitored and adjusted automatically to maintain them within acceptable levels.

    摘要: Novel methods for monitoring and recording fouling of aqueous systems are disclosed. The methods employ a heat transfer test assembly including an outer tube member, a heating rod positioned within the outer tube member, a ribbed tube sleeve fitted over the heating rod and thermocouples for sensing the wall temperature of heating rod. The heat transfer test assembly is connected to a monitoring and recording assembly that is connected to or includes a piping assembly. The piping assembly and the heat transfer test assembly are placed in fluid communication with a heat exchanger. Fouling determinations of fluid flowing through the piping assembly are made at varying flow rates with simultaneous monitoring and recording of the flow rates together with data, such as corrosion, pH, conductivity, and the like.
