[...]Saalbach-Hinterglemm, Austria Fine screening systems are an interesting alternative to primary settling tanks when it comes to changing the sludge stabilization process from aerobic to anaerobic. Compared with a traditional primary clarifier with a retention time of 0.5 to 2 hours, a fine screen achieves the same or better reduction rates, which take effect within a few minutes whilst requiring only a fraction of the space and volume. Energy savings and biogas yield through carbon removal Switching from aerobic to anaerobic sludge stabilization can reduce aeration costs by around 20–25%. This [...]

[...]Totalphütte, Alps, Austria The Totalphütte was originally a site hut for Vorarlberger Illwerke AG and served as accommodation for the construction workers building the Lünersee lake dam. Since 1964, the Austrian Alpine Club has been running the hut as a mountain refuge. Following a number of refurbishments and the reconstruction of the hut – it was severely damaged by a dust avalanche in 2019 – it has since become a popular destination for walkers and those conquering the Rätikon’s highest peak, Schesaplana, at 2,965 m. Wastewater treatment remains an important issue even in high-alpine environments[...]

[...]Bickenbach, Germany The European water sector will face enormous challenges in the coming years. Implementing the new EU‑Urban Waste Water Treatment Directive (UWWTD) and ensuring the sustainable protection of our water resources will be a significant collective task. UWWTD is therefore rightly regarded as a milestone that will shape urban water management across Europe in the long term: stricter requirements for the removal of phosphorus and nitrogen, energy neutrality and, above all, the widespread introduction of the fourth treatment stage. All sewage treatment works with a capacity of more[...]

[...]Baden-Württemberg, Germany A fourth treatment stage is currently being built at the sewage treatment works in Schwäbisch Hall, Markgröningen-Talhausen, Vörbach-Pfalzgrafenweiler and Meßkirch in Baden-Württemberg. These treatment works have opted for the GAC (German: GAK) process, which uses granulated activated carbon for adsorption. Upstream of the trace substance removal stages, there is a multi-stream pre-filtration system at each site, all of which have been equipped with the new HUBER Pile Cloth Media Filter RotaFilt®. These reliably protect the subsequent GAC‑adsorption process from[...]

[...]Every wastewater regulation specifies a limit value for ‘lipophilic substances’, which in practice are referred to as grease. As a rule, more than 90 per cent of the total grease concentration is often present as dispersed grease particles and emulsified grease. Conventional grit and grease traps at sewage treatment works can only retain non-dispersed, floatable grease (DWA M760). The remaining dispersed substances are separated in the biological treatment section of the sewage treatment works. Various grit chamber solutions Factory-built grit chambers are often combined with grease traps ([...]

[...]Kreßberg, Germany With the new EU Urban Waste Water Treatment Directive (UWWTD, German: KARL), phosphorus removal at sewage treatment works is increasingly coming into focus. At the same time, however, phosphorus loads from sewage treatment works are also one of the reasons why Germany still fails to meet the requirements of the European Water Framework Directive (WFD 2000). Not least for this reason, further measures will be necessary at many sewage works in the future. Flocculation filtration in Kreßberg At the Kreßberg (GK3) sewage treatment works in Baden-Württemberg, this issue is now viewed[...]

[...]Worldwide Grit chamber cleaners are generally reliable and safe, working around the clock, come rain or shine. Nevertheless, the ravages of time take their toll on the structure. After 30, 40 or even more than 50 years, even carefully maintained and well-looked-after cleaners eventually reach the end of their service life. Paving the way for the future It is wise to plan for the future cleaning of your longitudinal grit trap early on and with foresight. As is so often the case, there are various solutions available for this. However, before addressing the issue of grit channel clearance, it must[...]

[...]Stemwede, Germany At the Stemwede wastewater treatment plant in North Rhine-Westphalia, a major infrastructure project has been successfully completed in recent months: The plant’s mechanical pre-treatment system has been completely renewed. This involved the removal of two ageing screens and the refurbishment of the concrete channel. Subsequently, two modern HUBER Multi-Rake Bar Screen RakeMax® units with 5 mm bar spacing and a high-performance HUBER Wash Press WAP were installed. In addition, a HUBER Coanda Grit Washer RoSF4 has been operating reliably at the plant since 2004. Complex construction[...]

[...]Toronto, Canada In May 2025, Kevin Schneider embarked on the first service consultant tour of Canada – a country that impresses not only with its scenery, but also with its openness to sustainable environmental technology. In his report, Kevin recounts his journey, which offered a unique combination of intensive customer support and unforgettable experiences. One country, two oceans, and one goal: customer proximity The journey took me from Toronto via Calgary to the west coast and Vancouver Island. The tour in the Toronto region was organized by our subsidiary, HUBER Canada. In Calgary and [...]
