The file "MLE Strategy.pdf" details the control strategy for the MLE blower and dissolved oxygen system at the Cambria CSD wastewater treatment plant upgrade. It covers the monitoring and control of one rotary positive displacement blower via the plant's PLC and SCADA system, including dissolved oxygen probes in aeration basins, blower speed control through a VFD, and system operating constraints to maintain efficient aeration. The document specifies the integration of sensors, control logic, and operator interface for maintaining dissolved oxygen setpoints in the aeration process.
