[...]Sheboygan, WI, USA A new HUBER Belt Dryer project is on the way in the USA. A BT 18 dryer for a throughput of 11,700 t/a will be installed at Sheboygan in the US state Wisconsin. HUBER SE could win the order already in July 2012. We were commissioned to supply not only the belt drying plant, our scope of delivery includes also a HUBER Screw Press Q-PRESS®, size 800 for sludge dewatering. The HUBER Belt Dryer we supply to Sheboygan will be the first installation of the new dryer generation in the USA. The plant conception excels for its excellent energy efficiency and a high level of safety. The[...]

[...]Salt Lake City, USA Solar drying of sewage sludge is a technique that is increasingly used to reduce sludge disposal costs and at the same time protect the environment. Today, operators of even medium-sized and large wastewater treatment plants from all over the world appreciate our innovative and reliable solar dryers. The HUBER Solution for sewage sludge drying with solar energy is working with a continuous drying process, that is odourless due to complete restacking of the sludge. Its unique combination of sludge turning and transport performs both spreading and turning of the sludge as well [...]

[...]Penzing, Germany Solar sewage sludge drying has become a generally accepted ecological and economical technology. To make the implementation and operation of a solar drying plant a sustainable success, all relevant aspects need to be fulfilled: economic and planning aspects but as well acceptance on the part of the operator and the public. One of the plants that offer both, a perfect design concept and acceptance, is installed on WWTP Penzing-Weil near the Upper Bavarian lake Ammersee located southwest of Munich. About 8,500 residents are connected to this aerobic stabilised sewage treatment [...]

[...]Varna, Bulgaria The Bulgarian Black Sea Coast along the city of Varna with 300,000 residents is an important economic factor, especially due to its touristic potential. The European Union decided in 2002 to give aid money for the protection of the Black Sea, in particular for upgrading and building new local sewage treatment plants. The capacity of the sewage treatment plant at Varna could therefore be expanded to 450,000 PE and equipped with state-of-the-art technology. The main intention was to minimise the direct discharge of untreated wastewater to the Black Sea. They wanted to achieve that [...]

[...]Erlangen, Germany Convincing belt drying solution for sewage sludge At the beginning of 2021, HUBER was awarded the contract for the supply of a HUBER Belt Dryer BT 16 for WWTP Erlangen after an EU-wide public tender. In the run-up to the tender for this advanced sludge treatment project for a volume of 15,700 t/a, several processes were investigated. These were: Solar Sewage Sludge Drying Hydrothermal carbonisation Belt drying The decision was made in favour of the belt drying option, as this drying process allows the sewage sludge to be dried continuously to >= 90% DR. The thermal energy demand of[...]

[...]Sargans, Switzerland High level of user-friendliness increased even further In Sargans, Switzerland's first HUBER Screw Press Q-PRESS ® Q 800.2 was installed in 2017 for dewatering digested sewage sludge. The latest generation of screw press could win the competition against other systems due to its very high operational reliability and user-friendliness, complete stainless steel construction and very low operating costs. The demands on the system are extremely high. An essential factor is the required DR concentration in the dewatered sludge of over 30% with simultaneously clear filtrate quality.[...]

[...]Star, Idaho, USA The Star Water and Sewer District knew change was going to come. The plant’s existing in-channel grinder technology wasn’t just aging, it was obsolete. The unit was also in need of repairs that could force two weeks of downtime. Regardless of what they did to “fix” the existing unit, its performance would lag behind newer screening technology. Consultants and engineers pointed the district to HUBER and its ROTAMAT® STAR fine screen as a replacement that would take the plant into the future. The single-most important result that Star Sewer and Water District Waste Water [...]

[...]HUBER presents the HUBER Multi-Rake Bar Screen RakeMax® CF, an innovative variant of the well-proven RakeMax® system with a Centre Flow screen. The model impresses with its hydraulic throughput capacity by means of a U-shaped bar rack, even with small bar spacings and in narrow channels. It offers an optimal hydraulic utilisation of existing channels and the screen is unsusceptible to grit, gravel and stones. Due to its different design options the RakeMax® CF covers a very wide range of applications, allowing us to respond to the individual needs of our customers and to specific constructional[...]

[...]Coarse screens are the protective equipment of a screening system. Their task is not removing the incoming screenings from the water flow, but coarse screens are used to protect downstream finer screening systems (or machine technology in general) in the event that massive amounts of coarse material or extreme-size debris occur. Such unusual events in the operation of a screen include the occurrence of large-volume flotsam (e.g. tree trunks, tyres, etc.), man-sized screenings rolls, suddenly occurring huge quantities of screenings or large debris and sediment loads at the channel bottom. Such disturbing[...]

[...]An innovative building block for your digitisation strategy The main duty of the screens installed in the inlet to sewage treatment plants is to protect downstream machines and systems and ensure perfect operation of the sewage treatment plant. When selecting the headworks screens it is usually assumed that coarse material up to a certain maximum size will occur. Increasingly, however, unforeseen material such as cans, wood pallets, large tree branches or even iron rods are also found in sewers. Although such coarse material should definitely not be present in a sewer, there is no possibility [...]
