System Analysis of the Liebenwalde Wastewater Treatment Plant & Cost reduction through usage-based maintenance


WWTP Liebenwalde: The WWTP Liebenwalde had extremely poor efficient values and very poor efficiency. With 80% funding program, the WWTP Liebenwalde become one of the most energy-efficient plant in Germany.

AERprogress Condition Monitoring: Machines and components are used with varying degrees of intensity. Their degree of wear and tear is correspondingly differentiated. Usage-based maintenance precisely takes these differences into account and analyses the maintenance intervals required on an individual and usage-based basis. It aims to maximize the service life of equipment by permanently recording and evaluating the condition of the machine.
