[...]Replacing the primary clarifier with a fine screen – HUBER CarbonWin® In the HUBER CarbonWin® process, the primary clarifier is replaced by a fine screen. This results in the following advantages: Only 1/10 of the space required compared to conventional primary clarifiers Minimized investment and operating costs Suitable to be integrated into existing plants The primary clarifier is the last stage of the mechanical pre-treatment of a wastewater treatment plant and works according to the anaerobic sludge stabilization process. In the primary settling tank, undissolved organic and inorganic substances[...]

[...]Tailor-made solutions for fish protection We develop solutions that are both designed and implemented to be sustainable and long-lasting. Not only resource-saving manufacturing of our screens and screening machines is important to us, but also the optimization of structures for water abstraction projects and creating comprehensive concepts for fish protection. Technical options HUBER solutions for fish protection Optimal fish protection starts with the correct design of the structure and the screen concept. This also includes fish deterrent systems and specially shaped filter elements for [...]

[...]Adsorption with granulated activated carbon (GAC, German GAK) is a simple, reliable and, above all, low-maintenance process. This makes it ideal as a fourth treatment stage, especially for smaller wastewater treatment plants. The core component of the process is the HUBER Active Carbon Filter CONTIFLOW® GAC , which is filled with granulated activated carbon and acts as an adsorber for the micropollutants. The particle size of granulated activated carbon (GAC) is usually between 0.5 mm to 4 mm. GAC Granulated Activated Carbon The HUBER Active Carbon Filter CONTIFLOW® GAC is installed [...]

[...]Reduce Volume of Industrial Sludge Through Thickening, Dewatering or Drying In the wastewater treatment process, substances are removed from the wastewater and accumulate as screenings or sludge. In addition, biological processes, but also physical and chemical treatment processes such as the flotation process that is frequently used in industrial wastewater treatment, lead to the formation of sludge. Residues can also arise directly from industrial production in very liquid form. Process Technology HUBER solutions for reduction of disposal costs Depending on the upstream process step, the [...]

[...]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[...]

[...]Suitable materials and effective corrosion protection for economical solutions The right choice of material for screens and screening machines is a key factor for their reliable and low-maintenance operation. For applications with river water and fresh water, we use 304 and 316L stainless steel. For applications in particularly corrosive seawater with high temperature and salinity, we use stainless steel in combination with corrosion protection, corrosion-resistant duplex stainless steel, and super duplex stainless steel. All steel parts are pickled and passivated in our own production. For [...]

[...]Various solutions for conveying dewatered and dried sewage sludge Sludge transport plays an important role in the planning and construction of sludge drying plants. On the one hand, the dewatered sewage sludge has to be brought into the dryer, and on the other hand, the fully or partially dried sewage sludge has to be transported away from the dryer. When designing a particular transport solution, important criteria include not only the required transport capacity but also the sludge properties (moist, dry, sticky, dusty,...) and the desired degree of automation. Feeding and Removing Supply and[...]

[...]Various solutions for conveying sewage sludge The heart of an economical sludge dewatering system is the HUBER Screw Press Q-PRESS® , which is in use in thousands of installations worldwide. However, the right solution for the subsequent transport of the dewatered sludge into the provided containers is also of great importance for the implementation of an optimal and practicable dewatering process. HUBER offers various solutions for container filling, which can be differentiated in terms of sludge volume or sewage treatment plant size, number of containers and degree of automation. Solutions [...]

[...]Safe working in manholes – safe opening and access Manholes fulfill an important task in water supply and wastewater disposal. They are used where shut-off fittings in pipelines must be accessible, to control sections of very long pipelines, for aeration/deaeration, or access to complex installations (e.g. well shafts, pressure reduction shafts). Easy and safe access must be ensured in each individual application. Most of the manholes are entered from the top. This means that the operating personnel must open the manhole cover in order to be able to use an entrance aid for safe access. They must [...]

[...]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 [...]
