Abstract |
The application of modern control systems to the operation of wastewater-treatment plants is discussed. Control strategies for the commonly used wet- and dry-weather treatment processes and their collection systems are described. Wherever possible, the benefits derived from, as well as the operating problems associated with, the actual or proposed control strategies are documented. Cost/benefit analysis indicates that many untried feed forward mass proportional control schemes are economically attractive because of the low payback periods. Centralized control with semigraphic display should be used in treatment plants since it saves on operating labor, improves operation, and increases the safety of wastewater treatment. Automatic data acquisition systems are cost effective and should be used in medium and large sized plants. Direct digital control and computerized control can only be economically justified in large dry-weather treatment plants and large storm-water control networks. |
