[...]HUBER Technology Service has won the Open National Championship for sewage treatment professionals organised by the German Water, Wastewater and Waste Association (DWA). The competition took place during IFAT 2014 on the trade fair grounds in Munich. HUBER Technology Service competed as an industrial enterprise against the professionals from seven European sewage treatment works. The participants in the competition had to master demanding challenges in the field of measuring & control technology as well as complete sewage treatment works control with process technology. Moreover, they had to complete[...]

[...]The Bavarian State Ministry of Economic Affairs and Media, Energy and Technology has again announced the 50 strongest growing medium-sized companies for this year. The Bavarian environmental company HUBER SE is one of them. Companies who want to make it to the top 50 must have achieved an above average increase in their number of employees and turnover in the past years. Bavarian Economics Minister Ilse Aigner pointed out that the "Bavarian economy could never be as dynamic and innovative as it is without the outstanding performance of Bavaria's medium-sized companies. Nearly 40% of the total [...]

[...]The new HUBER Disc Dryer RotaDry® completes the HUBER product portfolio for sewage sludge drying with contact drying. In combination with a sewage sludge mono-incineration plant, the disc dryer dries the sewage sludge to the ideal TR content and is thus optimally suited for utilisation in fluidized bed incineration plants. The HUBER Disc Dryer RotaDry® is designed for homogeneous partial drying of dewatered sewage sludge. It can dry exactly to the required TR content, thus enabling self-sustaining incineration in the fluidized bed incinerator. The HUBER RotaDry® is available in different sizes[...]

[...]Saalbach-Hinterglemm, Austria Fine screening systems are an interesting alternative to primary settling tanks when it comes to changing the sludge stabilisation 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 stabilisation can reduce aeration costs by around 20–25%. This [...]

[...]Malta The Ta' Barkat sewage treatment works, often referred to as the Malta South STW, is at the heart of Malta’s wastewater management system. It is situated near Xgħajra on Malta’s south-east coast and officially came into operation in 2011. It is the country’s largest sewage treatment works and treats around 60,000 m³ of wastewater every day. This corresponds to around 80 per cent of the island’s total wastewater volume. The plant uses a modern biofiltration process that alternates between aerobic and anoxic environments to efficiently treat the wastewater. Its commissioning has significantly[...]

[...]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[...]

[...]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 ([...]

[...]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[...]
