[...]Penrith, UK Originally, the two existing perforated plate (escalator-type) screens at the Penrith wastewater treatment plant discharged their screenings into a launder trough wherefrom they were flushed to a tank incorporating macerator pumps. These pumps grinded the solids and returned them back to the works. Besides the fact that the entire system did only comminute the screenings, but did not remove any solids, the system did not operate reliably. The main problems encountered by the operators were that the macerator pumps required constant maintenance and that, under certain circumstances, the [...]

[...]Bayreuth, Germany and Lomianki, Poland HUBER solar sludge drying system with sludge feeding and removal on the same gable end – the feed comes back as dry sludge HUBER SE has continued the success story of its solar sludge drying system in 2014. Like on many other sites, whether in Europe or overseas, the SRT system convinced also the customer at Bayreuth in Bavaria and was the winner of the tender competition. The decisive point in favour of the HUBER SRT was that its concept ensured clever use of the scarce space on site. Feeding of the press/wet sludge and removal of the dry granulate takes [...]

[...]Munich, Germany A total of 1,816.6 million hectolitres beer were produced worldwide in 2008. Assuming an average fresh water consumption of 400 litres for one hectolitre beer, this means a fresh water consumption of 726.6 million m³. About one third of the fresh water, however, could be replaced with service water as it is not necessary to use highest drinking water quality in all production areas. A part of the saving potential of 240 million m³ water can only be exploited with the use of new technical solutions. Under a research project of the Bavarian Research Foundation and in cooperation [...]

[...]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[...]

[...]Bayonne, France The water board of the city of Bayonne supplies the drinking water for one third of the population (15,000 persons) from the valleys of Petchonea, Arquetce, Ipharager and Lapeyeren. In 2011, the Bayonne water association decided to refurbish their well shafts for drinking water supply. The refurbishment was necessary as the old bitumen coated manhole covers were leaking. The water board put the refurbishment of about 100 shafts out to tender. The tender specifications were for manhole covers including entrance ladders and installations. The cheapest offer was submitted by the [...]

[...]Leibnitz, Austria Leibnitzerfeld Wasserversorgung GmbH has set itself the target to ensure the supraregional water supply in South and Southeast Styria. With an annual water production of about 3 million m³ and daily peaks of up to 15,000 m³ they supply the drinking water for 39 municipalities and three joint communities with a total of of 100,000 PE. In total, they operate 11 well system, 42 elevated reservoirs (of which 20 of their own with a capacity of 10,000 m³), 60 pressure increasing plants, and a network of 170 km transport lines and 139 km supply lines. Furthermore, they network with the [...]

[...]In Germany, Austria and Switzerland, enough water of high quality is naturally available at any time. One could almost forget that our most important resource is highly sensitive and gives life not only to humans and animals but also to germs and microorganisms. There are therefore good reasons to protect our water resources and use air filters in drinking water reservoirs. “We have never always built water reservoirs without air filters. Why should we use air filters now?” You may have heard this provocative counter-question sometimes from a customer when you recommended that he should improve his[...]

[...]Berching, Germany Not only for critical wastewater but also as an alternative to overloaded aeration tanks and secondary settling tanks of municipal and industrial wastewater treatment plants Secondary settling tanks have to manage the important task of separating activated sludge. With diameters of sometimes more than 50 metres, most of them are horizontal flow systems. The sludge can settle inside while the virtually solids-free clear water runs off through a channel. The control and monitoring of such separation stages is still done visually in most cases through cyclic visibility depth [...]

[...]Freystadt, Germany HUBER sludge treatment solution on STP Freystadt – a concept that pays off for the operators The newly installed process chain replaces the previous system with contract dewatering and its associated problems. STP Freystadt is designed for approximately 8,000 PE. The sludge on site was previously dewatered only once a year. After the implementation of the new HUBER systems, comprising a HUBER Screw Press Q-PRESS® and a HUBER Sludge Turner SOLSTICE®, the plant operators can look forward to a smoother and easier plant operation, and the disposal costs incurred by the [...]

[...]Rehau, Germany HUBER Longitudinal Grit Trap ROTAMAT® Ro6 Bio and HUBER Grit Washer RoSF G4E increase operating reliability and reduce operating costs Bioenergiezentrum Hochfranken (BEZ) is an association of the town Rehau, the administrative districts Hof and Wunsiedel and some local companies supplying the town and districts with regenerative energy. Beside different plants from the companies involved, the biowaste fermentation plant is at the heart of the new concept. The fermentation plant treats the biowaste of the munipalities involved, covering nearly 40% of the local primary energy demand. [...]
