The load operation in organic wastewater treatment plants is subject to considerable fluctuations. With its high-performance compressors Delta Blower, Delta Hybrid and AerzenTurbo, AERZEN offers an impressive portfolio for the oil-free oxygen supply of aeration tanks in this field of application. The advantages of using the three technologies within a combined system are these: highest energy saving, best control range and lowest investment costs. The machine control system, AERsmart, is now the new intelligent component. Volume flows are carefully monitored so that low, medium and high loads can be processed in the most efficient way, with ideal performance scenarios integrated into the algorithm of the control system. Consequently, the installed machinery is able to operate at very close to the theoretical highest level of efficiency. AERsmart can provide the highest efficiency through the perfect interplay of up to twelve machines, including third-party products. AERsmart is the first master machine control system which can efficiently combine different machine technologies. Furthermore, unit data including pressure, volume flow, temperatures, energy consumption and fluctuating loads, as well as the machine data including service intervals, can be recorded and transferred to the control centre for further processing. So, changing requirements and possible ageing effects of the aeration system can constantly be monitored. Finally, AERsmart also convinces because it operates fully in line with new guidelines from the DWA guidelines (German Association for Water Economy, Waste Water and Waste) for the energy efficiency and energy analysis of wastewater treatment plants. And besides, as an intelligent interface, it is already pointing the way to Water 4.0.
