[...]Øystese, Norway I began my dual Bachelor's degree in Biological and Environmental Process Engineering at HUBER and the East Bavarian University of Applied Sciences in Amberg-Weiden in September 2021. The degree programme focuses primarily on natural sciences and engineering subjects such as fluid mechanics, mechanical and thermal process engineering, and water and wastewater treatment. In addition to theory, several practical projects must also be completed during the study-free periods. Practical experience at the HUBER Technology Centre I had the advantage of being able to gain practical [...]
[...]Schnaittachtal, Germany The Schnaittachtal sewage treatment plant has been in operation for almost 50 years and currently employs six male and one female sewage treatment operators. For many years, the plant has relied on HUBER machines for mechanical wastewater treatment, such as the HUBER Screenings Wash Press WAP® Ro4-OS, HUBER Screw Conveyor Ro8 and HUBER STEP SCREEN. These have now been replaced by a new HUBER Rotary Drum Fine Screen ROTAMAT® Ro2 size 1600 with a 3 mm bar spacing, a HUBER Screw Conveyor Ro8 T and HUBER Screenings Wash Press WAP® SL. A quarter of a century in service In service[...]
[...]Grand Rapids, MI USA An alternative for ageing scraper bridges. They work constantly, know no weekends and are exposed to wind and rain. They are familiar with wear and corrosion and are grateful for a few drops of lubricating oil. We are talking about the scraper bridges of grit channels. When the ravages of time take their toll At some point, after what feels like two sewage works operator’s lifetimes, the time comes when this ‘vehicle’ is no longer fit for purpose. The concrete of the grit channel could certainly withstand the same amount of time again, but the machinery has had its day.[...]
[...]Heiligenblut, Austria The Heiligenblut wastewater treatment plant, which has a capacity of 8,250 PE, was built at the foot of the Großglockner, Austria's highest mountain, in 1986. It treats the wastewater of the entire municipality of Heiligenblut (at an altitude of 1,288 m), including Kaiser-Franz-Josefs-Höhe, which is the highest point of the Grossglockner High Alpine Road (at an altitude of 2,369 m). The sewage treatment plant is located next to the Mölltal federal road in the village of Rojach, at an altitude of 1,098 metres. The challenge: limited installation space and high requirements The [...]
[...]Plants for sludge treatment (e.g. HUBER Screw Press Q-PRESS ® , HUBER Disc Thickener S-Disc) or for pre- and secondary treatment of industrial and municipal wastewater (e.g. HUBER Flotation Plant HDF) are usually purchased in Germany. This involves prior planning, authorisation, construction of infrastructure and buildings, as well as permanent responsibility for the acquired plant technology. In addition, the process from idea to implementation often takes several years. Industrial plant operators, in particular, increasingly wish and demand to rent rather than permanently purchase machinery [...]
[...]Germany Membrane systems, especially membrane bioreactors (MBR), are wastewater treatment technologies that combine biological processes with membrane filtration. These systems are used in some sewage treatment plants instead of the conventional activated sludge process. A typical MBR system consists of a biological reactor in which microorganisms break down organic matter and a membrane filtration unit that separates the purified water from the solids. Solids separation prior to membrane filtration To ensure optimum performance, membranes must be protected from large solids. For this purpose, [...]
[...]Wendelstein, Germany Since 2008, the ZV zur Abwasserbeseitigung im unteren Schwarzachtal (Lower Schwarzach Valley Sewage Treatment Association) has been retrofitting existing relief structures with screening systems to separate floating and coarse materials. These retrofits contribute significantly to greatly improving the discharge quality of rainwater from the combined sewer system into the receiving water. Installation of a screening plant at the Röthenbacher Straße stormwater tank with overflow In the stormwater tank with overflow at Röthenbacher Straße in Wendelstein, just outside [...]
[...]Combined Sewerage and Stormwater Treatment Protection of water bodies from polluted rainwater The advanced treatment of combined and stormwater in wastewater transportation systems is a main issue with regard to sustainable environmental and water protection. The building of new wastewater treatment plants and the upgrading or refurbishing continuous wastewater discharges has significantly increased the quality of many watercourses. Nevertheless, despite all efforts, ecological deficits still exist. Some of the problems are caused in the discharges of combined and separated sewers during storm [...]
[...]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 [...]
