Centrifugal pumps driven by asynchronous motor are widely used in industrial applications because of their low cost, high performance and robustness. However theses pumps can be damaged by wear and the performances of the machine can be altered.This research work deals with fault detection and diagnosis of fault that may appear in a pump. Usually, a vibratory or noise monitoring can be established, but it’s often really costly and can be cumbersome. A different approach based on the analysis and processing of the stators’ current is proposed here in order to highlight theses faults. This method can detect a torque drop in the pump shaft, and coupled with a flow measure it can determine if a cavitation is occurring or not. This provisional maintenance gives the health state of a pump in real time and only requires acquiring the current and using RMS and spectral analysis. For 2 years, Schneider Electric and International Office for Water have work together on this subject. For now, the methodology researches have been done and a first set of experiments has been led on an existing pedagogical platform at IOW (multi-stage centrifugal pump with an asynchronous motor, current, voltage, pressure and flowrate measurement).

Aqseptence Group trusted the Office International de l’Eau to support it in its R&D projects by entrusting it with the tests of the Triton ™ filter floor from Johnson Screens, a brand of the Aqseptence group. This partnership is part of the ERDF – SUDOE project TWIST (Transnational Water Innovation Strategy) in which OiEau is a partner. Installation of the new pilot The new pilot in place Inauguration of the new pilot In order to adapt to changing market needs and maintain its leadership, Aqseptence Group is constantly optimizing its processes, including Johnson Screens’ Triton™ filtering floor manufactured in France. The company has entrusted the performance qualification of this product to the OiEau, in order to guide it in its future innovations. In 3 months, the OiEau teams created a pilot on a semi-industrial scale at their La Souterraine site, which allows them to test the efficiency of the Triton™ system in real-life situations and to optimize its environmental impact (water and energy consumption). The results obtained will thus make it possible to demonstrate the strengths of the current product and to focus on the axes of new developments. Inaugurated on Monday 7 September, in the presence of teams from […]
The Urban Lisbon Living Lab (UL3), created under the framework of TWIST project, has joined with Lisbon Municipality to develop MAARTE project – Monitorização da Aplicação de Água Residual Tratada em Espaços públicos. MAARTE will develop a new methodology to assess the contamination levels of public green areas irrigated with treated wastewater. It will also assess several bacterial and virus concentrations in grass samples irrigated with potable water, ground water and treated wastewater. MAARTE is managed by Instituto Superior Técnico and the water utility Águas do Tejo Atlântico also participates as a reclaimed water producer. Public garden in Lisbon irrigated with groundwater
