[...]Vienna, Austria Project Scope The project comprises in detail: In the screening building: Replacement of the existing screens by HUBER Multi-Rake Bar Screen RakeMax® units: - Channel width: 3.0 m - Channel depth: 3.1 m - Maximum flow rate: 3.7 m³/s - Bar spacing: 8 mm The HUBER screens will be installed at an angle of 60° as this improves hydraulics, enlarges the screen surface area and reduces the flow velocity between the screen bars. The existing screenings wash presses will be replaced by HUBER Wash Press WAP® HD 8 units and the HUBER wash presses integrated into the existing screenings [...]

[...]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 [...]

[...]By generating electricity and heat from digester gas, operators of wastewater treatment plants with anaerobic sludge stabilisation can generate energy themselves, and thus significantly reduce the purchase of external energy and consistently and sustainably lower their operating costs. Under suitable conditions, by feeding external and organic-rich waste (co-substrates) into the digester, gas and thus energy production can even be increased to the point of energy self-sufficiency. Typically, liquid waste from the food industry or catering (such as grease separator contents or flotate sludge[...]

[...]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[...]
