The HUBER Screw Press Q-PRESS® is successfully in use worldwide and will be presented at IFAT in various sizes. The machines are continuously optimised by HUBER and offer best dewatering performance at highest energy efficiency. The simplicity of operation, ease of maintenance and the small footprint are further plus points of this machine. Special highlight: the interaction of an operating HUBER Screw Press Q-PRESS® and the new HUBER IoT platform will be presented live.
Both nationally and internationally, HUBER has implemented numerous projects in the field of thermal sewage sludge treatment.
For all solar sewage sludge drying plants, HUBER relies on the HUBER Sludge Turner SOLSTICE® in combination with the innovative HUBER climate control system. As a result of continuous development, HUBER solar sewage sludge drying systems are characterised by trouble-free operation, best energy efficiency as well as simplest operation and highest safety. Interested visitors can find out about the current status of the HUBER solar sewage sludge drying project at the Bahr El-Baqar plant (Egypt) at IFAT. This water treatment plant has been awarded the title of the world’s largest plant of its kind by Guinness World Records in 2021. More than two billion cubic meters of water are to be treated here annually on an area of about 650,000 square meters. HUBER supplied, among others, 128 Sludge Turners SOLSTICE® for the large-scale project, so that a total of approx. 490,000 tons of dewatered sludge per year can be dried from 24 % to approx. 75 % dry residue.
As an alternative to solar sewage sludge drying, the HUBER Belt Dryer BT is the ideal solution. Due to its modular design, the belt dryer can be adapted to on-site conditions both in terms of energy and construction. Innovative concepts for heat extraction from the drying process also enable maximum energy recovery. This can be fed into a local heating network, for example, or used at the sewage treatment plant to heat the digester. Interesting videos as well as operating data and operating experiences from numerous nationally and internationally executed dryer projects await the visitors.
The new HUBER Disc Dryer RotaDry® completes the HUBER product portfolio with contact drying. The disc dryer can, for example, dry the sewage sludge of a mono-incineration plant to the ideal dry residue content. Thus, the incineration can be operated in a self-sustaining and energy-efficient way. The excess steam from the electricity production is used as heating medium. A reliable condensate removal system, innovative control and optimised feeding make the HUBER Disc Dryer RotaDry® the perfect sewage sludge dryer for subsequent incineration.
The final step of thermal sludge utilisation is provided by the sludge2energy process of sludge2energy GmbH. sludge2energy GmbH, a joint venture of HUBER SE and WTE Wassertechnik GmbH, will also present its solutions for mono-incineration of sewage sludge at the HUBER stand. The first operating experiences of the sewage sludge mono-incineration plant in Halle-Lochau, which was planned and built by slude2energy GmbH, are likely to meet with particular interest among trade visitors. In addition, other current projects of sludge2energy GmbH for the mono-incineration of sewage sludge will be presented.
