[...]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 [...]

[...]From the screen to the screenings wash press – reliable and operationally safe solutions for conveying screenings HUBER offers two different solutions for providing tailor-made and project-specific conveying systems for wet and untreated screenings: Screenings transport by launder channel The screenings to be treated are discharged from one or more screens into the launder channel. Sufficient wastewater or process water is used to flush the screenings into the screenings wash press. The flushing water also serves as wash water for screenings washing. HUBER Launder Channels HLC can be [...]

[...]Reliable conveying technology for grit and mineral solids Grit is separated by sedimentation in grit chambers during wastewater treatment. The grit settling at the bottom of the grit chamber is then removed – usually discontinuously – from the grit chamber. Grit Feeding and Conveying HUBER offers different designs of grit traps for grit separation. All HUBER grit traps are equipped with an appropriate conveyor so that the separated grit can be discharged into a container or passed to further treatment in a grit washing plant . Depending on the grit chamber design, either grit discharge pumps or [...]

[...]The best access for your structure Accesses to structures for drinking water supply or wastewater disposal have high requirements. For drinking water supply structures, for example, a burglar-resistant door must be installed in accordance with DIN EN 1627. In the drinking water tank itself, access to the water chamber is required for maintenance. Pressure-tight doors are used for this purpose. To allow access above the water level, special water chamber doors must be used. In the field of drinking water supply and wastewater disposal, there are many shaft structures that require an access or [...]

[...]Treat and reuse process water and waste water Water reuse makes it possible to use water in cycles. This reduces both the consumption of fresh water and the amount of wastewater produced. Water recycling and reuse in industry in the context of "ZLD - Zero Liquid Discharge" plays an important role with regard to the economical use of water as a resource. The importance of irrigating agricultural land with treated municipal wastewater is also widespread in many countries, especially those with less rainfall, and will continue to increase due to climate change and the need for a sustainable "circular[...]

[...]Sharjah, UAE Population growth in Dubai and adjacent Sharjah is a consequence of rapid development. Population growth, enforced growing wealth and luxury, generate great strain on the infrastructure of these cities. All existing wastewater treatment plants are heavily overloaded. Several treatment plants are presently in the process of becoming extended and upgraded, but even when the construction and installation will be finished, the plants will hardly be able to treat the enormous and ever growing wastewater flows. Because of freshwater scarcity in this arid region, treated wastewater is viewed[...]

[...]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 [...]

[...]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[...]

[...]Complete process technology for the treatment of surface water Surface water can be treated into drinking water using the following physical, mechanical and chemical process steps: Coagulation: Dosing a coagulant to the raw wastewater Flocculation: Dosing a flocculant, and possibly a flocculation aid, to the raw wastewater results in the formation of flocs. Clarification: The flocs are separated from the water e.g. with a lamella separator. Filtration: The clarified water is then filtered to separate even the smallest solids and flocs. Depending on the requirements, single-layer or multi-layer[...]
