[...]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 [...]

[...]During dry weather, organic and inorganic sediments increasingly settle on the sewer base in combined sewer systems due to slow flow velocities. Under stormwater conditions, these sediments float up and arrive along with the sewer flow at the sewage treatment plant or stormwater overflow structure. If the combined sewer volume exceeds the capacity of the overflow structure or sewage treatment plant, the combined water is frequently discharged to a receiving water course, impairing water quality with the result of increased costs for maintenance and cleaning. As a preventive measure, coarse material[...]

[...]Kappern, Austria In Kappern near Marchtrenk, a town between Wels and Linz, lies Austria’s second biggest sewage treatment plant which is designed for 160,000 PE. The main collector A has to cope with a high combined rainwater and sanitary sewer flow. Due to the given specific conditions the stormwater overflow tank Kappern offered an interesting opportunity to combine the two HUBER storm screen types, ROTAMAT® Storm Screen RoK1 and ROTAMAT® Storm Screen RoK2. Due to the screens’ high flexibility and capacity only minor structural adaptation work was necessary to optimally realize this project[...]

[...]Fully automatic throughput and performance control HUBER develops a revolutionary control system for BT Belt Dryers: The system is able to adjust the plant throughput fully automatically to varying dry substance contents in the dewatered sewage sludge. Operator attendance is thus reduced to a minimum. Dewatered sewage sludge, even if coming from a sewage treatment plant, does usually not show constant properties. Variations in organic content, chemical composition or polymer necessarily lead to varying dewatering results. Minor variations can normally be balanced quite well, but variations greater[...]

[...]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[...]

[...]Berching, Germany The ships of the Endeavor series are the worldwide biggest mega yachts with ice class PC6. They allow expeditions to paradisiacal islands that would be impossible with conventional cruise ships. Main travel destinations are the Arctic, Antarctic and the Caribbean. The ship ‘Crystal Endeavor’ will for the first time set sail in 2020 and take its maximum 200 passengers in 100 exclusive suites to the most remote corners of the world. Two HUBER Membrane Screen ROTAMAT ® RoMem 780 units with 0,5 mm mesh size will be installed on the ship to clean the wastewater from the cabins[...]

[...]Hannover-Lahe, Germany The Hannover-Lahe project of HUBER and sludge2energy GmbH is progressing further: The two HUBER Disc Dryer RotaDry® 2050 M units are just before their hot commissioning. Using a heavy-duty crane, the two disc dryers, each weighing around 63 tonnes, were unloaded from the heavy-duty transporters on site in November 2021 and lifted directly into the building onto the prepared level. They will be used in the Hannover-Lahe sewage sludge mono-incineration plant (KVA) as pre-dryers for processing the sewage sludge into fuel. Shortly afterwards, the fluidised bed furnace and [...]

[...]Seefelden, Germany The Seefelden sewage treatment plant in the Überlinger See wastewater association on Lake Constance with 70,000 population equivalents is to receive advanced wastewater treatment to remove trace substances. The heart of the new treatment stage will be a process combination of ozonation and activated carbon filtration – on a technical scale that has never been realized in Germany before. For this showcase project, HUBER will supply 24 Active Carbon Filters CONTIFLOW® GAK for biological post-filtration and adsorption of trace substances after the ozonation stage. Investment [...]

[...]Septic sludge of around 70,000 inhabitants is collected in the surrounding area of the city of Lahti. Twelve different companies haul septic sludge. To prevent that they dump septic sludge into sewers or on wasteland, the city was looking for a place and method of treatment. The city selected a HUBER system for septic sludge receiving and pre-treatment at their existing central wastewater treatment plant. A card reader and flow meter permit data collection and billing. The incoming septic sludge is screened and the screenings, together with those from their existing wastewater screens, are [...]

[...]Bickenbach, Germany Advanced Wastewater Treatment: HUBER Active Carbon Filter CONTIFLOW® GAK and HUBER Disc Filter RotaFilt® Convince The Bickenbach Wastewater treatment plant (WWTP) will be the first WWTP in Hesse (Germany) to receive advanced wastewater treatment for the removal of trace substances. At the end of 2022, the wastewater treatment plant of size class 4 (35,000 population equivalents) will be extended by an ozonation system with a downstream four-line activated carbon filter stage and an upstream two-line cloth filtration as pretreatment. Among others, HUBER will supply two HUBER[...]
