Higher blower efficiency for aeration tanks

More than 70% of operating costs of a wastewater treatment plant are related to energy costs, arising when the aeration tanks are provided with air. The combination of this company’s blower, turbo and hybrid technology has previously offered efficient solutions in the industry. However, with the introduction of a new control combination, AERsmart (photo), performance can now be sustainably increased even further — additional savings of up to 15% can be achieved, says the company. AERsmart arranges volume flows amongst the machinery in a mode so that low, medium and high loads can be processed efficiently per an existing configuration, whereby the characteristic diagrams and the efficiency levels are integrated in the algorithm of the control system. As a consequence, the installed machinery is operated very close to the theoretical highest efficiency level. Even third-party products can be controlled via the overriding control system. AERsmart can arrange for optimized efficiency by interconnecting up to 12 machines. — Aerzener Maschinenfabrik GmbH, Aerzen, Germany
