  • Performance-based control system
    Patent number: 6510368
    Abstract: 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.
    Type: Grant

    Date of Patent: January 21, 2003
    Assignee: Ashland Inc.
