Instrumentation for Aeration Control Package

Aeration basins are an excellent way to reduce the nutrient load during water and waste-water treatment, but the energy costs of such systems can be high. The Instrumentation for Aeration Control Package provides all of the sensors and transmitters that water- and wastewater-treatment engineers need to gain better control over the efficiency and economics of the aeration basin in a single package. The instrumentation measures dissolved oxygen, suspended solids, temperature, air flowrates, air pressure, water level, ammonium, pH, nitrates, and thermal mass in the aeration basin. Measurement of these parameters can help to reduce the energy costs associated with aeration. The sensors connect to any programmable logic controller (PLC) or supervisory control and data acquisition (SCADA) system via 4–20-mA with HART, Profibus or other digital interfaces.
