[...]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.

[...]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[...]

[...]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[...]

[...]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[...]

[...]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[...]

[...]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[...]

[...]Prepared for the future with HUBER Retrofit Service The ravages of time not only affect the machine technology, but also the associated switchboard and control system. As a result, failures and malfunctions occur more frequently, especially on the sensitive PLC (programmable logic controller) components. With outdated hardware, a standstill in the near future is unavoidable. Function and operational safety are no longer guaranteed. Moreover, the manufacturers of the PLC hardware are already focusing on new technologies (IoT, Industry 4.0, etc.). This means that spare parts procurement is no longer possible[...]

[...]Basel, Switzerland Wastewater as a heat source for heat pump systems represents a highly efficient energy source and energy sink. Its use is however often limited to big sewer diameters and high flow rates. This article presents an alternative to the use of heat from sewer wastewater: the use of the exhaust heat of locally generated wastewater as a regenerative and sustainable energy source for the production of service water and heating buildings, like in the example of the old-age home Hofmatt in Switzerland that is described below. Introduction Due to the ever improving quality of building [...]
