[...]Summary The HUBER Disc Dryer RotaDry® is a robust and compact dryer design with a high water evaporation capacity in relation to volume and footprint. It is ideally suited for the partial drying of sewage sludge and for the interaction with a fluidised bed mono-incineration plant. Fully automated, it contributes to a relief of the operating personnel and an optimisation of the combustion of sewage sludge. Effective disc drying supports sewage sludge mono-incineration. A high percentage of phosphorus can be recovered relatively easily from the ashes produced by acid hydroloysis. This is of great[...]

[...]After 41 years, Hans Huber and Karl-Josef Huber retire from their position as managing directors. Dr.-Ing. E.h. Hans Huber and his brother Karl-Josef Huber have given up their position as CEOs but will stay with the company as members of the supervisory board. With Hans Huber’s son Georg Huber and Dr.-Ing. Oliver Rong, son-in-law of Karl-Josef Huber, the sixth Huber generation has taken over the management of the company that has been family owned for 175 years. With effect from 1st January 2010 Georg Huber is CEO of HUBER SE and further in charge of finances and personnel. Dr.-Ing. Oliver Rong[...]

[...]The wastewater expert Hans G. Huber receives the highest endowed European environmental award The Deutsche Bundesstiftung Umwelt (DBU), one of Europe's largest foundations that promotes innovative and exemplary environmental projects, awards the Deutschen Umweltpreis 2006 (German Environmental Award 2006) to Hans G. Huber, member of the board of directors of the Hans Huber AG, for his innovative decentralised wastewater treatment technology. The wastewater expert Hans G. Huber receives the highest endowed European environmental award for outstanding achievements in global environmental protection[...]

[...]Uhldingen-Mühlhofen, Germany In August 2023, after more than two years of construction, one of the most cutting-edge systems for the removal of trace substances was successfully put into operation at the Uhldingen-Mühlhofen association sewage treatment plant. At the heart of the new treatment stage is a combined process of ozonation and activated carbon filtration on a technical scale that had not yet been implemented to date. 24 HUBER CONTIFLOW® GAC activated carbon filters and HUBER TT7 pressure door HUBER supplied the two-lane activated carbon stage with a total of 24 CONTIFLOW® GAC activated[...]

[...]India The joint venture A.T.E. HUBER Envirotech continues to grow in the field of sludge dewatering, achieving considerable success with the HUBER Screw Press Q-PRESS®. To provide optimal support for the first commissioning projects in India, twelve of the partner’s service technicians completed two intensive online training courses delivered by the HUBER Service Academy. This laid an important foundation for a smooth project start and the sustainable transfer of knowledge. Deepening technical and process knowledge The first training module focused on the technical fundamentals of the supplied[...]

[...]In Germany, Austria and Switzerland, enough water of high quality is naturally available at any time. One could almost forget that our most important resource is highly sensitive and gives life not only to humans and animals but also to germs and microorganisms. There are therefore good reasons to protect our water resources and use air filters in drinking water reservoirs. “We have never always built water reservoirs without air filters. Why should we use air filters now?” You may have heard this provocative counter-question sometimes from a customer when you recommended that he should improve his[...]

[...]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 ([...]

[...]Emschermündung, Germany The hydraulic capacity of the wastewater treatment plant Emschermündung is 30 m³/s. This is a gigantic flow, larger than of any other German, perhaps even European, wastewater treatment plant. The wastewater arrives at the plant not via conventional sewers, but its inflow is the river Emscher. The treated effluent of the plant enters the river Rhine. This is the reason why the plant’s name is Emschermündung, meaning “mouth of the Emscher”. The river Emscher flows through the northern part of the old industrial heartland of Germany, the Ruhr region. The Emscher river is [...]

[...]Grit Traps and Classifiers The best solution for any grit separation application Grit Trap and Classifier Product Groups Longitudinal Grit Trap Lamella Grit Trap Circular Grit Traps Complete Plants Grit Classifier For reasons of operating reliability of wastewater treatment plants it is necessary to separate grit, gravel and other mineral materials transported with the wastewater (an average of 16 gal. to 264K gal ( 60 l to 1000 m³) of wastewater according to DWA Work Sheet M369) from the digestible organic material. Good grit separation prevents operational problems, such as grit sedimentation[...]
