Reliability Improvements in Sewage Pumping Using Diagnosis with active Reaction

The presentation deals with a new approach in diagnosis systems especially for sewage pumping stations. Special focus lies on reducing operational problems due to clogging within the pumping system. Whereas actual Diagnosis systems just give out warnings about operational or mechanical problems, the new developed system is able to initiate automatically an adequate reaction to avoid or remove clogging. Reactions are done by the existing components or with special electrical/mechanical actors, both controlled by the diagnosis front end or by pump control software. The automatically reaction is integrated in upcoming complex remote control systems for sewage pumping systems of medium to large size cities. Increasing reliability and reducing energy consumption result in overall better economy.
