Produce with improved energy efficiency and remain competitive with AERZEN

Load operation in wastewater treatment plants is subject to considerable fluctuations. Collection and subsequent evaluation of the operating data from a blower station with the high-precision methods of AERaudit delivers actionable results on the current utilisation and efficiency, and informs how it can be designed to run much more efficiently in the future.

AERaudit is an innovative service developed exclusively by AERZEN to improve the energy efficiency of wastewater treatment plants. Municipalities in particular need to make savings wherever possible, and wastewater treatment plants are often their biggest energy consumers. 60 to 80 percent of the total energy requirement of a wastewater treatment plant is generated in the field of biological aeration. As an analysis specialist, AERZEN is a competent partner for running energy checks, and undertaking meaningful analysis in order to optimise energy consumption by blower stations.
The basis for a process and energyefficient clarification plant is inventory analyses and evaluation of the current operating data. Here, the actual load requirement must be determined and the savings potential demonstrated. In three steps AERaudit can derive the most economical and future-oriented plant configuration.
The AERaudit service is a component of Water 4.0, a forward-looking process orientation in water management. As one of the market leaders in wastewater technology, AERZEN accompanies its customers on their journey towards Water 4.0 with the holistic concept AERwater, which includes solutions for digitalisation, automation and resource efficiency. AERaudit provides the data basis.

Three steps to transparency

1. On-site measurement: the AERZEN service team brings transparency to the key figures of your blower station. A mobile measuring station records the relevant data in your ventilation system. Volume flow, system pressure, temperature and kW output are measured live and recorded in the form of load profiles.

2. Analysis: evaluation of the recorded data is carried out carefully and in detail at AERZEN headquarters – every low and peak load, no matter how small, is registered. Based on the results, AERZEN experts then develop one or more solutions tailored to customer requirements that are as efficient as possible.

3. Report: all data of your blower station is displayed in detail and transparently. Temperatures, load profiles and energy consumption are visualised and explained in detail in the form of diagrams. We will also show you your customised Performance3 solution with the ideal machine configuration. In addition, what the saving potential of energy or CO2 is and which amortisation times can be achieved.
