[...]Faroe Islands The Faroe Islands are probably known mainly to nature lovers with a penchant for rather unusual destinations. So it was initially something interesting and different for a change when HUBER received an enquiry in mid-2017 for a faecal sludge treatment plant for predominantly domestic sludge. At least 10,000 t of sludge were to be received annually, screened and then dewatered to ≥ 35 % dry residue (DR). Transport with suction and tanker vehicles What makes this project special is first and foremost the input DR: The sludge is collected island-wide with suction and tanker vehicles[...]

[...]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[...]

[...]Uhldingen-Mühlhofen, Germany In August 2023, after more than two years of construction, one of the most cutting-edge systems for the removal of trace substances was successfully put into operation at the Uhldingen-Mühlhofen association sewage treatment plant. At the heart of the new treatment stage is a combined process of ozonation and activated carbon filtration on a technical scale that had not yet been implemented to date. 24 HUBER CONTIFLOW® GAC activated carbon filters and HUBER TT7 pressure door HUBER supplied the two-lane activated carbon stage with a total of 24 CONTIFLOW® GAC activated[...]

[...]Central Hesse, Germany Mittelhessen University of Technology (THM) university of applied science intends to exploit a previously quite unknown potential with a new system: heating and cooling with energy from wastewater. The new plant, with the HUBER ThermWin system at its core, was commissioned at the end of May by THM's executive committee, Giessen's Mayor Frank Tilo Becher and Ayse Asar, State Secretary at the Hessian Ministry of Science and Art (HMWK). THM President Prof. Dr Willems: “previously untapped wealth” The plant is located at THM's Wiesenstraße campus. With canteens, numerous [...]

[...]Hanover, Germany The sewage sludge recycling plant in Hanover-Lahe will go into operation after successful hot start-up and optimisation: the plant, which has been equipped with two HUBER RotaDry® 2050 M disc dryer units, now recycles sewage sludge from the surrounding sewage treatment plants every day and supplies 5,000 households with district heating from a renewable source. The opening ceremony for the sewage sludge recycling plant took place on 6 July in the presence of Dr. Manfred Schüle (Managing Director of enercity contracting GmbH), Dr. Susanna Zapreva (Chief Executive Officer of enercity[...]

[...]The first step of operationally reliable and efficient wastewater treatment The separation of solids in wastewater with screens and fine screening systems is the first step in municipal and industrial wastewater treatment. The main task here is to remove all coarse and foreign materials that could inhibit or hinder the function of subsequent wastewater treatment stages. The following factors, among others, must be taken into account when planning an operationally reliable solids separation solution: Maximum required hydraulic throughput Expected screenings quantities Required bar spacing or [...]

[...]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[...]

[...]Over the years, the screw presses of the Q-PRESS ® series have become one of the most successful HUBER products. The latest leap in development took place with significantly more wear-resistant and powerful scraper lips and matching, higher-torque gearboxes with reduced electrical energy consumption. Current further development: significantly changed filter geometry The two long-proven sizes 280 and 440.2 will in future be equipped with a significantly increased open filter surface. In order to increase the open filter surface, the first, relatively coarse screen section in the inlet area will[...]

[...]Luzern, Switzerland Due to the increasing building density, cities are generally faced with the problem of lesser and lesser infiltration of rainwater water during storm events and the associated increasing risk of overflowing local sewers. Moreover, road runoff water contains not only grit and gravel but also considerable amounts of eco-toxicologically relevant substances from tyre wear and tar residues, for example heavy metals, such as cadmium, zinc and lead, as well as polycyclic aromatic hydrocarbons [PAH] and petroleum-derived hydrocarbons [PDH]. During rainfalls, the abrasion particles[...]

[...]Shanghai, China Megacities and their problem with construction waste Example: Shanghai Beside Beijing and Hong Kong, Shanghai is one of the most important industrial locations and market places in the People’s Republic of China. In the recent years, the city has had a remarkable growth spurt. Fifty years ago, about seven million people were living in the metropolitan area Shanghai, today the city has more than 25 million inhabitants. Along with the city’s growth came innumerable building projects with huge amounts of construction waste and other waste products. More and more of such material [...]
