Make savings potential visible

Load operation in wastewater treatment plants is subject to powerful fluctuations; wastewater quantities and contamination levels sometimes change rapidly. A detailed analysis of the current operating data in order to be able to meet the individual requirements as precisely as possible is the basis for a process- and energy-efficient wastewater treatment plant. AERaudit's high-precision methods are used to determine the actual load requirement of your plant in order to identify potential savings and make your operation more efficient in the long term.

Bij het zoeken naar de meest efficiënte oplossing, is het daarom noodzakelijk om machinetechnologieën zodanig te configureren dat ze voldoen aan de specifieke vereisten van elke installatie. Vroeger was het gebruikelijk om blowers van slechts één grootte te installeren, maar vandaag de dag zijn de installaties vaak voorzien van een combinatie van verschillende groottes of zelfs verschillende technologieën. Savings of up to 30% are possible - and in the shortest possible time. The application of a variety of tailored machine technologies facilities a rapid ROI, because the energy balance connected with the conversion results in considerable savings.

Do you know the savings potential of your system?

1. Meting op locatie:

The AERZEN service team lends transparency to the numbers from your blower station. A mobile measuring station is used to record your relevant aeration data. Volumestroom, systeemdruk, temperatuur en vermogen in kW worden direct gemeten en vastgelegd in de vorm van belastingprofielen.

2. Analyse:

The evaluation of the recorded data is carried out carefully and extensively at AERZEN headquarters, every low and peak load, no matter how small, is evaluated. Based on the results, our experts develop one or more concepts that are tailored to your requirements and as efficient as possible.

3. Rapport:

Alle gegevens van het blowerstation worden transparant en gedetailleerd weergegeven. Temperaturen, belastingsprofielen en energiekosten worden gevisualiseerd in de vorm van diagrammen en in detail besproken. We also present your tailor-made Performance3 solution with the optimal machine configuration. In addition, how large the saving potential of energy and CO2 is, and which amortisation periods can be achieved.


Benefit from the energy saving potential of 30% on average and payback times of less than two years.

Be able to operate load profiles optimally

AERaudit is an innovative service developed exclusively by AERZEN to analyse the energy efficiency of wastewater treatment plants. Met name gemeenten moeten zich richten op kostenbesparingen, omdat rioolwaterzuiveringsinstallaties hun grootste energieverbruikers zijn. Maar liefst 60-80% van de totale energiebehoefte van een afvalwaterzuiveringsinstallatie wordt gebruikt voor biologische beluchting. An optimal solution for energy-efficient oxygen supply requires that the blower configuration be tailored to individual load profiles and thus meets the highly fluctuating air requirements as accurately as possible. A systematic approach and extensive expertise are required, because the process sequences in wastewater treatment are complex.

As an analysis specialist AERZEN is your competent partner: the collection and evaluation of the operating data with the high-precision methods of AERaudit provide binding results about the current capacity utilisation and profitability and about how these can be made much more efficient in the future.
