AERaudit creates transparency about savings potential of wastewater treatment plants

07/05/2018

AERZEN, a market leader in wastewater technology, is showing clients the way forward to the new process paradigm in the water industry known as ‘Water 4.0’. As part of the 360-degree approach taken by AERwater spanning digitalisation, automation and resource efficiency solutions, AERaudit is a service exclusively developed by AERZEN for analysing the energy efficiency of wastewater treatment plants to obtain a basis in data.

Municipalities in particular must focus on cost savings because sewage treatment plants are their largest energy consumers. As much as 60-80% of the total energy required by a wastewater treatment plant is used for biological aeration. As an analysis specialist, AERZEN is an expert partner in energy auditing to obtain a reliable energy analysis for optimizing the energy consumption of blower stations. To make gains towards process and energy-efficient sewage treatment, a status analysis involving an evaluation of current operating data is needed. Actual electricity needs have to be gauged to demonstrate cost-saving potential. AERaudit takes you to the most economical, cutting-edge plant configuration in three steps.

On-site measurement:

The AERZEN service team creates transparency regarding the key performance indicators for your blower station. A mobile measuring station records the relevant data for your ventilation system. Volume flow, system pressure, temperature and power consumption are measured in real time and recorded in the form of load profiles.

Analysis:

The recorded data are painstakingly and thoroughly evaluated at AERZEN headquarters, including every load dip and spike, however small. Based on these results, our experts then develop one or more efficiency-maximizing concepts tailored to your requirements.

Report:

Your complete blower station data are mapped and charted in transparent detail. Temperatures, load profiles and energy costs are visualized in diagrams and discussed in detail. We also present your tailor-made Performance3 solution with the optimal machine configuration, how much money you can save on energy and CO2 and possible payback periods.
