[...]Vilshofen, Germany At the start of 2026, a comprehensive one-off plant maintenance was carried out on the HUBER machines at the Vilshofen sewage treatment works in Lower Bavaria. Designed for a population equivalent of 56,000, the plant is operated by Vilshofen Municipal Wastewater Services. During normal plant operation, one or two staff members are usually on site. Since 2007, the sewage treatment works has used two HUBER Rotary Drum Fine Screen ROTAMAT® Ro2 1000/5 units and one HUBER Coanda Grit Washer RoSF4/2. These are supplemented by two vortex washers from a third-party manufacturer. As part[...]

[...]Pachacútec , Peru HUBER supplies the technology for solar sewage sludge drying for the wastewater treatment plant in Pachacútec. The plant, located more than 10,000 kilometres from HUBER’s Berching site, is already the second project in Peru using the innovative drying technology with the HUBER Sludge Turner SOLSTICE® and solar energy. HUBER supplies innovative components for sewage sludge drying using solar energy HUBER supplies three HUBER Sludge Turner SOLSTICE® 11 units and the conveying system consisting of two HUBER Screw Conveyors Ro8 T 355 with a total length of about 70 metres. In [...]

[...]Toronto, Canada Noventa Energy Partners relies on HUBER ThermWin Noventa Energy Partners is using innovative technology to reduce the negative environmental impact of the existing energy supply for the Toronto Western Hospital. Over the life of this project, Toronto Western Hospital will see a cumulative reduction in greenhouse gas emissions of approximately 169,000 tonnes - equivalent to the annual CO2 emissions of approximately 52,000 cars. Mayor of the City of Toronto: "Great initiative to tackle climate change" These figures are matched by the statement of John Tory, Mayor of the City of [...]

[...]Energy-efficient use of waste heat for drying sewage sludge The sludge is dried either with cold air (HPS ® ) or with hot air (BT) in a belt dryer. The dried product has a solid concentration ranging from 70% DS up to 95% DS. The HUBER Cold Air Dryer HPS ® is designed for small sewage treatment plants while the HUBER Belt Dryer BT is designed for medium to large treatment plants. The HUBER Belt Dryer BT is used for the belt drying process, which operates according to the convection drying principle. The dewatered sewage sludge is fed onto a drying belt with an extruder. Air, heated by heat [...]

[...]Efficient drying process for partial drying of sludge The HUBER Disc Dryer RotaDry® is used for the disc drying process. A disc dryer is a contact dryer that transfers heat to the medium to be dried via direct contact of the hot disc. HUBER is an expert in drying processes and designs the optimal drying plant based on the individual requirements to ensure an economically and ecologically optimal utilization of the sewage sludge. Disc Drying of Sludge The entire disc dryer process consists of the following main components and process steps: Intermediate storage and feeding To ensure continuous[...]

[...]Using the energy of the sun Solar drying of sludge uses the energy of the sun as a thermal energy source. This provides a very ecological, environmentally friendly, and energy-efficient process for the treatment of sludge from wastewater treatment plants or water purification plants. The basic principle of the process is that the sludge is dried in a greenhouse structure. The sludge can be brought into the greenhouse manually, for example with a wheel loader, or automatically, directly from the dewatering facility by means of special conveying units. In the greenhouse, the sludge must be distributed[...]

[...]From the screenings wash press to the container – reliable conveyor technology for any requirement After the screenings have been washed and dewatered in the HUBER Wash Press WAP® , they have to be discharged into the collection container. Depending on the amount of screenings and the local conditions, this transport operation can be simple or very complex. In the simplest case, the HUBER Wash Press WAP® discharges the screenings directly into a container standing next to the wash press. However, as soon as longer distances have to be covered and/or the screenings have to be transported from[...]

[...]Identification of the ideal time for screw shaft maintenance Maintenance of the HUBER Wash Press WAP® as and when required Sensor with signal LED on the HUBER Wash Press WAP® Also for retrofitting to the HUBER Wash Press WAP® The aim of the HUBER Wash Press wear detection system is to enable a preventive maintenance strategy. The system detects a threshold value in the diameter loss of the compacting screw in the closed compaction zone section of the wash press. This part of the compacting screw is usually the machine component subject to the most wear. At the same time, however, it is difficult [...]
