[...]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[...]

[...]Extensive know-how, decades of experience and intensive studies and discussions: building on this foundation in sewage sludge treatment and recycling, HUBER launched the new HUBER Disc Dryer RotaDry® in 2020. The dryer is based on the functional principle of contact drying via steam-heated discs and, compared to other drying processes, impresses with its compact design as well as several innovative features, functionalities and decisive advantages for reliable state-of-the-art drying of sewage sludge. Fully automatic control Online measurement of the dry residue at the inlet and (optionally) [...]

[...]HUBER extends its product portfolio by a contact dryer for sewage sludge HUBER SE has expanded its range of sewage sludge dryers by adding a disc dryer to its future product portfolio. This dryer is based on the principle of contact drying and convinces by its compact design compared to other drying systems. Especially in combination with fluidized bed incineration systems, the HUBER Disc Dryer RotaDry® is the ideal addition to the overall process of a sewage sludge incineration plant. The strength of the disc dryer lies in the efficient, homogeneous and compact partial drying of sewage sludge[...]

[...]Berlin, Germany Reliable and innovative products from Berching for the German capital: HUBER will deliver four RotaDry® disc dryers to Berlin for the Waßmannsdorf sewage sludge utilisation plant, which is located on the site of the sewage treatment plant of the same name. In future, the HUBER Disc Dryer RotaDry® units will be used for partial drying of up to 40,800 kg/h sewage sludge. 100% thermal utilisation of sewage sludge in future Berliner Wasserbetriebe (BWB) operates six of its own sewage treatment plants in Berlin and the surrounding region. Instead of agricultural utilisation or [...]

[...]Hamburg, Germany On the way to Germany's largest sewage sludge incineration plant: HUBER supplies three HUBER Disc Dryer RotaDry® units for the extension of VERA Hamburg by HAMBURG WASSER. The extension will increase the capacity of the VERA incineration plant by approx. 50 percent. As a result of the extension, the annual throughput of sewage sludge at the plant will increase to about 76,000 tonnes dry matter, with further potential for expansion to 97,000 tonnes per year. Energy self-sufficient showcase sewage treatment plant Digester sludge has been treated thermally in an environmentally [...]

[...]The HUBER Disc Dryer RotaDry® is designed for homogeneous partial drying of dewatered sewage sludge. Due to its compact design and high specific water evaporation, it is ideally suited not only for use in new sewage sludge mono-incineration plants, but also for capacity expansions of existing plants. The dryer can dry exactly to the required DR content, thus enabling self-sustaining combustion in the fluidised bed incinerator. The HUBER Disc Dryer RotaDry® is available in different sizes, so that a water evaporation of two to six tons per hour and dryer can be achieved. The perfect sewage sludge[...]

[...]STP Vorra , Germany STP Vorra chooses a HUBER RoDisc® Screen The trickling filter plant with separate secondary clarification tank on STP Vorra was built in 1982 and had to be redesigned in 2006 to meet ATV-DVWK A281 standards. It was necessary to build a new bigger secondary clarification tank with a volume of 350 m³. Taking into account the conditions on site (soil properties, high groundwater level) the costs for building this new clarifier (including sheet pile, unwatering, distribution structure, inlet/outlet line, secondary clarification tank) were estimated to amount to approximately € 525,000[...]

[...]Zell am See, Austria The Austrian municipalities Zell am See and Bruck an der Glocknerstraße operate a water supply facility together which is fed from a spring at 940 m above sea level. The minimum delivery of the spring is about 40 l/s. It lies in the Fuscher Valley near Salzburg in the Glockner mountain chain. The highest peak of the Glockner mountains and Austria's highest mountain is the Großglockner. Directly after the well shaft the drinking water flows through an inverted syphon through the valley bottom to the inlet structure where it is filtered by a HUBER RoDisc® screen. The RoDisc[...]

[...]With the HUBER RoDisc® Rotary Mesh Screen we have risen to the challenge of increased requirements on future wastewater treatment. New technical developments combined with innovative manufacturing technology ensure the HUBER RoDisc® Rotary Mesh Screen is ahead of future requirements in wastewater treatment. Maximum corrosion protection is an indispensable prerequisite in wastewater treatment. HUBER has used a pickling bath for many years already to achieve the optimum passivation of stainless steel surfaces. Increasing requirements (chemicals in filter inlet) and increased use of the Disc [...]

[...]Schwabach, Koblenz, Frankfurt Niederrad For almost 20 years already, HUBER SE has provided successful solutions for the treatment of road sweepings, sewer grit and grit from sewage treatment plants. With more than 170 projects executed worldwide HUBER has gained extensive experience in the treatment of STP grit, sewer grit and road sweepings. Our solutions have continuously been further developed in the course of the past years. The major challenge has been and still is the different composition of the raw material which can have a massive impact on downstream grit treatment systems. The result[...]
