[...]Screw presses have been proving their worth for many years at wastewater treatment plants with population equivalents ≤ 100,000 mainly because the simple operating principle offers advantages compared to other continuously operating dewatering units such as decanter centrifuges: The use of the sludge feed pressure (0 – 300 mbar) as a control variable enables automatic adjustment of the machine and flocculant settings to fluctuations in the sludge consistency. Time-consuming readjustments by the operator are thus reduced to a minimum, and the dewatering system can typically be operated unattended[...]

[...]Constance, Germany Lake Constance, with a water surface of about 536 km² the largest lake in Germany and the largest freshwater reservoir in Central Europe, has been used for the drinking water supply of the city of Constance for more than 110 years. Due to the already excellent quality of Lake Constance water, the waterworks can provide up to 50 million litres of drinking water for the Constance region every day with comparatively few treatment steps. Excellent drinking water quality through microfiltration, ozonation and sand filters The raw water is pumped out of Lake Constance from a depth[...]

[...]Madrid-Butarque, Spain It is a successful large-scale project at the gates of the Spanish capital: HUBER successfully commissions 18 HUBER Multi-Rake Bar Screen RakeMax® units in the Madrid-Butarque stormwater retention basin. After ten years of less than satisfactory operation with products from other manufacturers, combined with high additional expenses, the City of Madrid renewed the facility in the south of the city with innovative and reliable products from HUBER. With a capacity of up to 400 million litres (400,000 m³), the stormwater retention basin is one of the largest of its kind in[...]

[...]Challenges in mechanical preliminary wastewater treatment Screens, such as the HUBER Multi-Rake Bar Screen RakeMax® , are used in the inlet of wastewater treatment plants to remove coarse contaminants from the incoming wastewater stream. At the same time, such preliminary screens also protect the operation of downstream machinery and units, such as a screw conveyor or a wash press, and ensure the smooth operation of the entire wastewater treatment plant. In addition to the type of material to be expected, however, other unforeseen materials often get into the inlet of the sewage treatment plant[...]

[...]The city of Nuremberg has two sewage treatment plants in the city centre. One is the Nuremberg I STP on Adolf-Braun-Straße and the other is Nuremberg II on Gertrudstraße. Both plants process the wastewater of the city of Nuremberg and rely on HUBER's sustainable and efficient machine technology, particularly for mechanical pre-treatment of the wastewater. At STP I, the screen and grit chamber are from HUBER, and the screening system at StP II is also from HUBER. In the past, HUBER had already supplied several of its WAP® wash presses to the two sewage treatment plants. This provided valuable insights[...]

[...]Villach, Austria For many decades, the coarse screens designed as direct current screens served their purpose in the Villach sewage treatment plant, which has a capacity of 250,000 PE. During rainfall events, it often happened that the resulting amounts of screenings could no longer be conveyed because the single rake was unable to hold them. The reason for this was that the clearing interval lasted more than one minute – a circumstance that led to the accumulation of screenings in front of the screen during a flushing surge, which in turn often resulted in the collapse of the screening system. [...]

[...]Salzburg, Austria The wastewater treatment plant in Siggerwiesen in the municipality of Bergheim, which borders the city of Salzburg to the north, has been in operation since 1986 and treats approx. 40% of the total wastewater generated in the city and province of Salzburg. The first expansion of the sewage treatment plant took place between 1994 and 1998, followed by further adaptation measures between 2003 and 2004. With a capacity of 680,000 PE60 and a dry weather inflow of 103,600 m³ per day, the Siggerwiesen municipal sewage treatment plant is the largest in the province of Salzburg. The[...]

[...]The ”World of Clean Water“ opened the doors of its company headquarters: In bright sunshine, HUBER opened the gates of its corporate headquarters on Saturday, 2 July, from 8 am to 2 pm and invited the public to an open day. The interest of the visitors from the region was great, the cafeteria piazza accordingly full, the number of participants in the factory tours high. Even Berching's First Mayor Ludwig Eisenreich did not miss the opportunity, came to see for himself and exchanged views with Dr. Oliver Rong (Director Engineering & Production, Deputy CEO of HUBER SE) and Human Resources Manager[...]

[...]Passau, Germany Since 1 June 2006, the Passau wastewater treatment plant and HUBER SE have been linked by a continuous, trusting and successful service partnership. Over the course of two decades, numerous HUBER‑systems have been reliably serviced, maintained and technically upgraded – a milestone that impressively underlines the importance of professional manufacturer maintenance. The Passau wastewater treatment plant, designed for 110,000 population equivalents and operated by a dedicated team of ten staff members, has relied on HUBER‑technology for many years. The plant’s equipment includes[...]
