Aqualogic® / Enerlogic®

The best and most comprehensive controller solution for wastewater treatment

The various - often opposing - individual processes in sewage treatment plants place the highest demands on the process control of the biological treatment stage. Classical controllers quickly reach their limits here. The Aqualogic® controller, on the other hand, is based on Fuzzy Logic and is, therefore, able to evaluate any number of system parameters in parallel and to interpret them optimally - the result is a robust and reliably working wastewater treatment plant.
Aqualogic® thus ensures a stable, load-dependent, and energy-efficient operation of the most important part of a sewage treatment plant.
Aqualogic® is highly scalable and due to its modular structure, it can be adapted highly flexible to the specific needs of a wastewater treatment plant and its specific and individual process flows. Should the processes change over time, Aqualogic® can be easily extended or adapted at any time.
Thus Aqualogic® is and remains the component that controls the most important part of a sewage treatment plant reliably and permanently and ensures its stable operation.
Aqualogic® is currently installed on nearly 400 wastewater treatment plants of sizes between 300 and 1,200,000 PE in 8 countries.
