Es wurden Checklisten zur anlagenspezifischen Identifizierung von Optimierungspotenzialen für Kläranlagen mit Faulung entwickelt. Wesentliche Ziele sind die energetische Optimierung der Anlagen, die Reduzierung der Schlammmengen für die Entsorgung und die Sicherstellung der Abwasserreinigung auf einem hohen Niveau. Ein Überblick über die Ansätze zur Optimierung bestehender Faulungsanlagen, die Checklisten sowie Ergebnisse bei deren Anwendung wird gegeben. [less ▲]

SK-DSSy: how to integrate the YouTube platform in a cooperative decision support?

In wastewater treatment plants (WWTPs) domain, the decision support tools are nowadays necessary in order to efficiently process the large databases generated with on-line sensors. In this paper a cooperative decision support system (DSS) is presented. This DSS uses a KPI-based fuzzy logic engine to analyse the plant performance and identify the operational conditions that occur in the plants. Then, it associates the detected operational conditions with YouTube pages in which videos are uploaded to provide details and propose suggestions. The YouTube platform is then used to share and validate suggestions by means of the comment functions and the 'likes'. This approach is innovative, free of costs, and useful for plant managers that can rely on a user-friendly platform. [less ▲]

A data-driven methodology to support pump performance analysis and energy effiency optimization in wastewater treatment plants

Studies and publications from the past ten years demonstrate that generally the energy efficiency of Waste Water Treatment Plants (WWTPs) is unsatisfactory. In this domain, efficient pump energy management can generate economic and environmental benefits. Although the availability of on-line sensors can provide high-frequency information about pump systems, at best, energy assessment is carried out a few times a year using aggregated data. Consequently, pump inefficiencies are normally detected late and the comprehension of pump system dynamics is often not satisfactory. In this paper, a data-driven methodology to support the daily energy decision-making is presented. This innovative approach, based on fuzzy logic, supports plant managers with detailed information about pump performance, and provides case-based suggestions to reduce the pump system energy consumption and extend pump life spans. A case study, performed on a WWTP in Germany, shows that it is possible to identify energy inefficiencies and case-based solutions to reduce the pump energy consumption by 18.5%. [less ▲]

One of the most promising cement alternatives are geopolymer cements. The term “geopolymer” was mentioned for the first time by Davidovits1 and classifies all forms of inorganic polymeric material synthesised by chemical reaction of aluminosilicates and an alkaline activating solution. The production of geopolymer binder comprises in two main procedures: calcination and geopolymerisation. The synthesised geopolymer shows interesting characteristics like good mechanical properties, high strength and good durability. [less ▲]
