[...]Schallstadt, Germany The energy turnaround has already been under discussion for several years. The events on the energy market in 2022 at the latest have now made it very clear to the public that there is a very great need for reorientation on the “heat market”. The discussions about the right fuel are in full swing. HUBER SE has a solution that does not require any fuel at all: it is based on exploiting the energetic potential of wastewater using the HUBER ThermWin system. Energy from wastewater replaces renewable and fossil fuels In Schallstadt in Baden-Württemberg (Breisgau-Hochschwarzwald[...]

[...]Screw presses have been proving their worth for many years at wastewater treatment plants with population equivalents ≤ 100,000 mainly because the simple operating principle offers advantages compared to other continuously operating dewatering units such as decanter centrifuges: The use of the sludge feed pressure (0 – 300 mbar) as a control variable enables automatic adjustment of the machine and flocculant settings to fluctuations in the sludge consistency. Time-consuming readjustments by the operator are thus reduced to a minimum, and the dewatering system can typically be operated unattended[...]

[...]Isle La Plume, WI, USA In 2021, HUBER Technology Inc., the Denver, North Carolina-based subsidiary of HUBER SE, was awarded the contract for the modernisation of the La Crosse wastewater treatment plant located on Isle La Plume. The city of La Crosse, with a population of around 52,000, is located in the state of Wisconsin, which is situated in the Midwest of the USA. Total investment volume of around 60 million US dollars The scope of supply includes a HUBER Multi-Rake Bar Screen RakeMax® CF in the screen building in the inlet to the WWTP, a HUBER Belt Dryer BT 18 for sewage sludge drying, and a [...]

[...]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 [...]

[...]Munich, Germany A total of 1,816.6 million hectolitres beer were produced worldwide in 2008. Assuming an average fresh water consumption of 400 litres for one hectolitre beer, this means a fresh water consumption of 726.6 million m³. About one third of the fresh water, however, could be replaced with service water as it is not necessary to use highest drinking water quality in all production areas. A part of the saving potential of 240 million m³ water can only be exploited with the use of new technical solutions. Under a research project of the Bavarian Research Foundation and in cooperation [...]

[...]Ingelheim, Germany HUBER Active Carbon Filter CONTIFLOW® GAK: The quaternary treatment stage Boehringer Ingelheim Pharma GmbH & Co.KG was founded by Albert Boehringer in Ingelheim on the Rhine in 1885. The company operates a central wastewater treatment plant on their research and development location in Biberach an der Riß (Baden-Württemberg). The treated wastewater is discharged directly to the receiving water course. As part of a research project investigating the reduction of trace substances and micropollutants, a partial flow of the wastewater generated daily is treated there. This partial[...]

[...]Berching, Germany Simple and low-cost method of phosphorus removal from wastewater The nutrients we discharge into water courses (phosphorus, nitrogen) severely impairs water quality in the long run. Even phosphate contents in the lower microgram range can already have a negative effect on the oxygen content in waters and thus increase their eutrophication potential. Eutrophication is referred to as the enrichment of a water body by plant nutrients (overfertilation). These nutrients lead to increased algae growth, and algae make the water turbid. After some time, only the surface-near layer [...]

[...]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[...]
