[...]Amsterdam, Netherlands When the Dutch sewage treatment plant Amsterdam-West was modernised in 2006 it was redesigned for the treatment capacity of 1,000,000 PE. In addition, more than another 1,000,000 PE external sludge can be treated there. In the past, particularly the treatment of primary sludge was a problem in terms of the operating reliability of the entire sludge line. The solids contained in the different types of pre-treated sludge and from the transport tanks cause high wear and lead to unforeseeable maintenance work requirements on pumps, digestor internals and sludge dewatering [...]

[...]STP Vorra , Germany STP Vorra chooses a HUBER RoDisc® Screen The trickling filter plant with separate secondary clarification tank on STP Vorra was built in 1982 and had to be redesigned in 2006 to meet ATV-DVWK A281 standards. It was necessary to build a new bigger secondary clarification tank with a volume of 350 m³. Taking into account the conditions on site (soil properties, high groundwater level) the costs for building this new clarifier (including sheet pile, unwatering, distribution structure, inlet/outlet line, secondary clarification tank) were estimated to amount to approximately € 525,000[...]

[...]Zell am See, Austria The Austrian municipalities Zell am See and Bruck an der Glocknerstraße operate a water supply facility together which is fed from a spring at 940 m above sea level. The minimum delivery of the spring is about 40 l/s. It lies in the Fuscher Valley near Salzburg in the Glockner mountain chain. The highest peak of the Glockner mountains and Austria's highest mountain is the Großglockner. Directly after the well shaft the drinking water flows through an inverted syphon through the valley bottom to the inlet structure where it is filtered by a HUBER RoDisc® screen. The RoDisc[...]
