Inbetriebnahme der ersten HUBER TT7-30 Drucktüren im Wasserwerk Echthausen
Wickede-Echthausen waterworks in the Ruhr Valley was built in 1942. About 35 hectares are available there for drinking water production. The Wickede-Echthausen waterworks belong to Wasserwerke Westfalen (WWW), a subsidiary of DEW21 and GELSENWASSER. With around 138 employees, they produce drinking water for 1.5 million people. Six waterworks between Wickede and Witten treat the water of the river Ruhr and make it available as drinking water. The supply area includes parts of the southern Münsterland region, the central and eastern parts of the Ruhr Valley and the northern Sauerland area. In 2014, Wasserwerke Westfalen produced about 100 million cubic metres of drinking water. About 25 million cubic metres of it are the per year capacity of the Echthausen waterworks
where an additional building (80 x 35 m) is under construction presently to complete the drinking water treatment plant and provide for additional technical water treatment steps (fig. 1). This plant consists of oxidation with ozone to break up persistent compounds, quick filtration for the removal of particles, and an activated carbon fixed-bed filtration for the removal of organics. Moreover, the existing chemical deacidification system with caustic soda is being replaced by a physical process that works without any addition of chemicals. In advance of the overall project, Wasserwerke Westfalen started already in 2010 to change the drinking water disinfection systems on their waterworks to systems that use UV light. This technology is even more efficient against potential pathogenic germs than the previously used chloroxide.
Die Lieferungen der insgesamt 136 Schachtabdeckungen verteilten sich über mehrere Monate, da immer nur Teilabschnitte erneuert werden konnten. Die Versorgungssicherheit musste zu jeder Zeit gewährt sein. Die Montage stellte einen enormen logistischen Aufwand dar, da die Schächte an schwer zugänglichen Stellen zu montieren waren. Durch eine sehr gute Vorbereitung und den montagefreundlichen HUBER Schachtabdeckungen konnte eine verbindliche Lieferterminzusage gemacht und eingehalten werden. Insgesamt wurden über fünf Monate ständig mehrere Mitarbeiter der Fa. Miremont für die Arbeiten eingesetzt.
HUBER also contributed to these conversion measures with the delivery and installation of a new product, the HUBER Pressure-Tight Door TT7.30. This product extends the application range of HUBER pressure-tight doors, which were previously designed for the pressure of a 10-metre water column. The new TT7-30 pressure-tight door is designed for a significantly higher pressure of up to 30 metres water column and is now available for a wide range of applications.
At the Echthausen waterworks, the three new HUBER Pressure-Tight Doors TT7.30 are required as inspection openings for the ozone reaction chambers. The water volumes flow through the plant with overpressure. The three pressure-tight doors must be able to withstand that pressure. Easy access is ensured by the easy-to-operate central lock.
