Wastewater treatment plant operators use chemicals, biological organisms and physical processes to recycle and produce environmentally safe water for use in irrigating public parks and landscapes throughout their cities. While not treated to the high standards required for human consumption, the safe water may also be returned to the environment in recharging the water table or being dispensed into rivers, lakes or oceans. In the first stage of treatment, the larger bulk solids are removed and separated from the wastewater. Here, an EchoSpan ultrasonic level transmitter is installed over a waste sump following the initial separation process. The non-contact sensor provides continuous level data to the SCADA, which in turn, periodically empties the sump, transferring the wastewater to the next stage of treatment. EchoSpan is reliable sump level measurement.
