[...]Bickenbach, Germany The European water sector will face enormous challenges in the coming years. Implementing the new EU‑Urban Waste Water Treatment Directive (UWWTD) and ensuring the sustainable protection of our water resources will be a significant collective task. UWWTD is therefore rightly regarded as a milestone that will shape urban water management across Europe in the long term: stricter requirements for the removal of phosphorus and nitrogen, energy neutrality and, above all, the widespread introduction of the fourth treatment stage. All sewage treatment works with a capacity of more than 150,000 population equivalents (PE) and, in sensitive areas, those with more than 10,000 PE, must retrofit this additional treatment stage by 2045. It is not yet clear how many sewage treatment works in Germany and Europe will actually be fitted with trace substance removal systems. However, it is expected that in Germany alone, around 600 sewage treatment works will be fitted with a fourth treatment stage. To date, over 60 German sewage treatment works have already been upgraded with an industrial-scale fourth treatment stage, including 33 plants in Baden-Württemberg, which, together with Switzerland, has taken on an important pioneering role in this field. A small selection of these successfully implemented case studies is presented in the fact sheets opposite. The projects impressively demonstrate that, from a technological perspective, the successful implementation of an industrial-scale fourth treatment stage is already possible today. It is now up to European policymakers to promptly develop and present a pragmatic solution for the financing of the UWWTD that is acceptable to all parties.[...]

[...]Mooresville, North Carolina, USA The ninth belt dryer project was sold in the USA in 2022. The USA has thus established itself as the second largest belt dryer market in the HUBER Group. There is no doubt that the foundation stone for this success was laid in the Mooresville belt dryer project in North Carolina: This year we are celebrating 10 years of operation of the plant in Mooresville. The BT 20 belt dryer (formerly known as BT 5-2) serves the wastewater treatment plant with a maximum capacity of 28,400 m3/d (7.5 MGD). Since its commissioning in 2013, this dryer has made a significant contribution to efficient waste management and the sustainable utilisation of resources. ”Town brown”, the brown gold of Mooresville The belt dryer is loaded with non-stabilised excess sludge from the sewage treatment plant. This is dewatered to 18% DR using a belt filter press. The dewatered sewage sludge is then dried to at least 90% solids content. This is passed on to local farmers for agricultural use. Among farmers in the region and in internal circles, the dried sewage sludge is also called ”town brown” – the ”brown from the town”, the "brown gold of Mooresville" – because of its colour and the place where it is dried. Heat is supplied to the plant by a hot water boiler fuelled by natural gas. The dryer is designed for a water evaporation rate of 1,300 kg/h and offers the well-known and widely appreciated advantages of the HUBER belt dryer design: Sludge extruder for optimum feeding onto the dryer belt Minimised dust production Temperature control in the individual dryer modules The tenth anniversary of the dryer operation was used as an opportunity to talk with the wastewater treatment plant manager, Jamie Levis, and the sludge treatment plant manager, Larry Hendren, about the operating experience and future plans. The lively exchange of information allowed a look behind the scenes of this historic project for HUBER. Over 75,000 operating hours in total In the course of this, the experience gained from 10 years of operation, during which more than 75,000 operating hours were accumulated, was discussed in great detail. It was noted that it naturally takes some time to optimise the operation of such a system. This applies to the maintenance of the system as well as the special operating conditions of the individual system components. It also requires a machine operator who, as in most cases, should enjoy familiarising themselves with the machine technology and the subject matter. Insights from the plant personnel The plant personnel start their day with a daily inspection of the plant. According to Larry Hendren, this involves paying particular attention to the noises made by the individual components, which could indicate any developing susceptibility to faults. Smooth operation can be easily guaranteed with an appropriate stock of spare parts and proactive monitoring and maintenance work. In combination with stocking individual components, downtimes can be minimised and an average availability of the system of over 8,000 h/a can be guaranteed. The following key points were mentioned: Operation of the hot water boiler: water quality control Fresh air supply to the dryer: seasonal check of the antifreeze content for heat recovery Sludge delivery pump: rotor and stator replacement required, mechanical seal is preferable to normal packing seal Motor bearings of blower drives Sludge feed extruder + Perforated extruder plate + Cutter drive: - Axle bearing - Cutting knives High satisfaction with plant operation The sewage treatment plant staff are highly satisfied with the operation of the plant. This is also manifested in the fact that the staff regard the operation of the dryer as a personal matter when interested visitors come to see the plant. But it is also reflected in the large number of references that the Mooresville plant has provided for HUBER. This includes responding to enquiries from planning offices, through to personal visits to the plant, including answering questions relating to operation, maintenance and costs. The positive feedback from colleagues at the Mooresville wastewater treatment plant, especially Jamie Levis and Larry Hendren, regarding the belt dryer is certainly a major reason why the story of belt dryers in the USA has become a success story. Further HUBER products in use It should be mentioned in this context that other HUBER products are also in operation at the Mooresville WWTP: Tank-mounted HUBER Rotary Drum Fine Screen ROTAMAT ® Ro2 (1000, 6 mm) Third treatment stage for treatment plant effluent: Four HUBER Disc Filter RoDisc ® 18 units HUBER Multi-Rake Bar Screen RakeMax ® with Wash Press WAP ® , pumping station to the wastewater treatment plant The Mooresville WWTP is also available for testing plants of HUBER Technology, Inc., the HUBER subsidiary in the USA. These include the Screw Press S-PRESS and the Sludgecleaner STRAINPRESS ® . Firmly established in the region over the years It should also be noted that the operation of the belt dryer has become firmly established in the region over the years. The final product of the drying process is gladly purchased by several agricultural businesses in order to return the nutrients to the cycle. Hay production or grass production are examples of this. The use of dried sewage sludge has also manifested itself in the figurative naming. Farmers can't get enough of ”town brown”, the brown gold of Mooresville.[...]

[...]HUBER SE receives order for the largest sewage treatment plant in Northern Ireland With its 280,000 inhabitants Belfast, the capital of Northern Ireland, is the second largest city on the island of Ireland. Situated at the mouth of the river Lagan in the Bay of Belfast the city represents one of Northern Ireland's 26 administrative districts. Three of the six million Irishmen live in the Dublin-Belfast corridor, along the motorway. In 2011, HUBER SE supplied already the complete mechanical pre-treatment equipment for Dublin, the biggest city on the island of Ireland. Now we have received the order to supply the equipment for the large sewage treatment works Belfast in two phases. The project comprises six HUBER Wash Press units of the biggest available size WAP/SL/12. Phase 1: Stormwater Tunnel The first phase "Stormwater Tunnel" was already completed successfully in November 2009. In order to eliminate flooding within the city, Northern Ireland Water started work on building the sewer in 2006. It involved taking the combined sewers from the whole of the city to channel this to a common facility located at and on the city’s WwTW. It was a 40 m deep sewer holding 85,000 m3 of waste water, 9.4 km long with 19 access shafts located about the city. At the end of this tunnel the terminal pumping station in a large 40 m deep chamber complete with pumps to take excess flow back into the inlet works. Flows in excess of this however were to be screened using 2 off new 12 m diameter 6 mm drum screens screening 12,000 l/sec each. In this first stage of completion, two Wash Press WAP® SL 12 units with a throughput capacity of 15 m³/h raw screenings each (redundant design) were installed successfully. The Wash Press units are fed via a launder channel system. The great advantage of this system is that complex transportation ways can be designed very easily and with a high operating reliability. The flushing water is also used as wash water for the Wash Press. The HUBER Launder Channel for complex transportation ways, type HLC, ensures reliable feeding of the WAP® SL wash presses. The very high screenings treatment standards are fully met with 35% DS content being achieved with < 20 mg BOD / g DS. Phase 2: Main Inlet Works After the successful completion of the stormwater tunnel project the client’s next task was to look at upgrading the main inlet works at this site. Based on the outstanding success of the HUBER WAP® SL units installed, the end-client was happy to work with HUBER to engineer a solution to meet both a high flow requirement as well meet very tight and difficult hydraulic constraints on site. Managing the large elevated structure, as well as meeting the requirement to phase the installation, was of paramount importance to the client. If this was not undertaken correctly then severe overtopping and pollution issues could arise. Different design options were presented to the client, and after numerous site visits and design review meetings a solution was eventually agreed. This comprised of the supply of 6 off RakeMax® screens, 2,152 mm wide, 50 mm bar spacing coarse screens, followed by 6 off EscaMax® 2,252 mm wide, 6 mm perforated plate fine screens with each bank of screens having dedicated duty / standby WAP® SL size 12 screenings handling units installed (4 off in total) each unit, uprated to give a maximum of 15 m³/hr raw screenings. Like in first project phase, a launder channel system is again used to remove the screenings into the Wash Press units. The phased installation and commissioning of the units is well underway and is due to be complete very soon. The work so far has gone to plan and the feedback from the first phase of the installation shows the project is a great success.[...]

[...]The success story of the HUBER ROTAMAT® machine family began 45 years ago. The patent for the HUBER Fine Screen ROTAMAT® Ro1 was filed at that time, and the ROTAMAT® family has continued to prove itself ever since through continuous innovation and adaptation. The patent described a combination of screening, dewatering, compaction and transport. Over the years, further variants of the Ro1 system, which is equipped with a screen basket and a rake, have been developed. These include the Ro2 with a rotating wedge wire basket, the RPPS, which has a perforated plate screen basket, and the latest variant, the ROTAMAT® STAR with a folded perforated plate screen basket. Over 9,000 machines in use Today, over 9,000 machines in various designs are in use in a wide range of areas and industries. Despite our many years of success, we are committed to innovation and renewal, ensuring that we always offer our customers the best possible solutions. Adjustable perforated plate: manufacturing and customer benefits All of the machines described above have a trough installed in the screen basket area in which the screenings are collected. Until now, this has been manufactured as a permanently welded perforated plate. The adjustable perforated plate offers considerable advantages in the manufacturing process. This allows the basket area to be adjusted more precisely and easily to the screw conveyor. Process engineering advantages This simplifies manufacturing and offers process engineering advantages for our customers. The possibility to adjust the perforated plate more effectively makes screenings conveying even more efficient in operation. Our customers have found that wear can occur on the screw shaft after years of use. With the adjustable perforated plate, this area can be readjusted to extend the machine's service life and increase efficiency. Adjustable slider: adaptable to specific requirements The adjustable slider in the machine’s discharge zone has already been successfully implemented in large machines. However, our customers' requirements vary, as does the composition of the screenings, which leads to different degrees of dewatering. The adjustable slider now allows for optimal adjustment to individual situations and levels of dewatering on our smaller machines, too. This enables a tailor-made solution for each customer and helps increase operational efficiency. Always at the cutting edge Through continuous innovation and adaptation to our customers' needs, we always remain at the cutting edge and offer solutions that meet the highest requirements. Even after 45 years, we continue to optimise our ROTAMAT® systems and adapt them to meet our customers' ever-changing needs.[...]

[...]On Thursday, 16 December, HUBER SE said goodbye to four long-serving employees as they entered their well-deserved retirement. The employees Richard Bayerschmidt, Wolf-Dietrich Gräper, Roland Kuttig and Erwin Meyer had been with the company for altogether more than 168 years. The executive board, human resources department and works council gave the former employees a fitting farewell and transition into retirement during the official farewell ceremony at the HUBER Forum. A total of 168 years of professional experience at HUBER: the Berching-based company officially bid farewell to four long-serving and valued employees in retirement. The farewell ceremony took place in compliance with all applicable Corona rules in the HUBER Forum at the company headquarters in Berching. After a meal together, Dr. Oliver Rong (Vice CEO) thanked the employees for their decades of loyalty to the company. Works Council Chairman Robert Freygang, Sales Manager Franz Heindl and Human Resources Manager Michael Hiller also expressed their thanks. “168 years of experience spread over four employees: You have made a great contribution to the success of the company through your work at HUBER – for this I thank you on behalf of the Executive Board and all employees,” said Vice CEO Dr Oliver Rong. “I wish you all the best for your well-deserved retirement and that you can use and enjoy the extra free time.” Richard Bayerschmidt: machining and milling, from 1973 to 2021. What it means to remain loyal to a single company for a (professional) lifetime is shown by the career of Richard Bayerschmidt. He started as an apprentice at HUBER on 3 September 1973 and, following his successful final examination, was employed in the machining department before operating various milling machines from the 1990s until his retirement. Bayerschmidt remained loyal to HUBER until his retirement on 31 August 2021. Wolf-Dietrich Gräper: field service, North Rhine-Westphalia region, from 1992 to 2021. Wolf-Dietrich Gräper spent 29 years at HUBER: starting in May 1992, he concentrated as a field sales representative in the North Rhine-Westphalia region on the sale of HUBER products from the Safe Access Solutions (SAS) range. Gräper developed considerable market potential in this area. Until his retirement, which will officially take place on 31 December 2021, he distributed HUBER’s entire product range in the same area. Roland Kuttig: welder, from 1978 to 2021. When Roland Kuttig started at HUBER in 1978, the company had not yet specialised in stainless steel alone. So it happened that in his early days as a welder he processed excavator parts and presses made of steel weighing up to 40 tonnes. After the company switched to manufacturing stainless steel products, Roland Kuttig was employed in the body shop of machine manufacture, where he has strengthened the team of the HUBER Wash Press WAP® body manufacture in recent years. Erwin Meyer: surface finishing, facility manager, etc., from 1973 to 2021. As an “all-round talent” at HUBER, Erwin Meyer has become known throughout the company: in 48 years of service, Meyer passed through various areas of responsibility after joining the company in September 1973 until his official retirement. He was responsible for surface finishing and pickling of stainless steel products, was deployed as a safety specialist and was a water protection, waste and crane officer. In the final stage of his time at HUBER, he was responsible for lift maintenance and all facility management tasks. Meyer’s final retirement date was 31 May 2021.[...]

[...]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 opening. These have to fulfil various characteristics such as having a centrally raised profile, being flush, burglar-proof, flood-proof, backwater-proof, for pedestrian traffic or load-bearing.

[...]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® GAK , 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® GAK is installed downstream of the biological treatment stage. The wastewater flows through the carbon bed and the trace substances are adsorbed onto the activated carbon. An additional separation stage downstream of the HUBER Active Carbon Filter CONTIFLOW® GAK is not required. After reaching the adsorption capacity, the loaded activated carbon is replaced by fresh carbon. The loaded activated carbon can be reactivated and then used again for adsorption. One way of optimizing the process, depending on the requirements and boundary conditions, is to use ozone. In this case, an ozonation stage is provided upstream of the adsorption stage. Ozone (O3) is a strong oxidizing agent and is therefore able to oxidize at least some of the organic trace substances that are difficult to degrade. This significantly increases the broadband effect and also extends the service life of the activated carbon. In practice, the use of a filter stage before the elimination of trace substances has proven successful. This allows dirt and impurities to be reliably separated and thus do not reach the activated carbon bed or the ozone system. In addition to being easier to maintain, the filtration stage can also be used as a flocculation filter for phosphorus elimination at the same time, resulting in a valuable synergy effect. For this application, both the HUBER Rotafilt® cloth filter and the HUBER CONTIFLOW® sand filter are ideal key components.[...]
