[...]Optimisation of existing treatment concepts through adapted machine technology Industries that produce wastewater with above-average pollution levels must either pre-treat it before discharge into the sewer or treat it completely biologically before it can be returned to water bodies. The relevant regulations result from the Water Resources Act, or from local statutes and environmental legislation. Since these industries can usually provide wastewater treatment with comparatively few resources, necessary optimisations are often not undertaken, and this is reflected in particular in increased operating and maintenance costs. Process Technology HUBER solutions for reduction of operating costs Regular evaluation of the plants often reveals a wide range of optimisation and cost-saving potentials: Optimisation of the mechanical preliminary treatment system Installation or optimisation of chemical-physical wastewater treatment Installation or optimisation of secondary treatment (filtration, flotation) Use of wastewater heat In principle, the more solids and organic matter that can be removed by mechanical and physico-chemical processes, the lower the operating costs of wastewater treatment. In contrast, aerobic treatment is significantly more expensive because of the energy costs. In case of high amounts of dissolved organic matter, anaerobic treatment may also be useful. HUBER has suitable machine technology and long experience in industrial wastewater treatment. Thus, previously undiscovered potential for improvement can be uncovered. Prior laboratory and pilot tests are used to determine the potential very precisely in advance. In principle, the entire HUBER product portfolio is used, but especially the HUBER Dissolved Air Flotation Plant HDF , the HUBER Screw Press Q-PRESS® , as well as the HUBER Disc Filter RoDisc® and the HUBER Pile Cloth Media Filter RotaFilt® .[...]

Preventive maintenance and inspection on a manufacturer quality level and their benefits for the customer, such as high operational reliability high machine performance calculable operating costs maintenance of value and investment security professional and reliable support of the operating staff on site detailed documentation and report of results after each maintenance for the plant managers are factors which are gaining in importance, both in Germany and abroad. Individually and flexibly designed HUBER service systems – a suitable solution for every customer Due to their modular design and flexible solution concepts HUBER service and maintenance contracts can be optimally tailored to suit customer needs and help to maintain customer satisfaction in the long term. Meanwhile, nearly 1000 sewage treatment plants, with in total 2000 machines in Germany alone, make use of the extensive benefits! No matter which branch, whether common municipal sewage treatment works or industrial plants, sewage sludge drying plants, dairy producers, automobile manufacturers, or even jails – they all went for a HUBER Service partnership, with good reason as one of our customers reports below! Example: Expanded HUBER service and maintenance contract of Verbandsgemeinde-Werke Bitburger Land – branch Bitburg and Kyllburg We are especially happy about one of our major HUBER service and maintenance partnerships with Verbandsgemeinde-Werke Bitburger Land which was signed in November 2015 after a merger of the municipal utilities and is now one of our most extensive HUBER service and maintenance contracts! With 20 sewage treatment plants and a total of 23 machines this maintenance contract includes both older machines of the year 1992 and completely new ones installed in 2014. This shows that continuous systematic maintenance from the manufacturer ensures that a very long operational life is achieved and the maximum machine lifetime can thus be utilized by plant operators. And there is another decisive advantage we could offer our customer for his new machines: extended warranty to 4 years according to VOB/B (German Construction Contract Procedures) instead of the usual 2 years. This bonus can be granted according to VOB if the customer commissions HUBER to take over the maintenance of new machines for the complete warranty period. HUBER service engineer Torsten Winzer during regular annual maintenance on one of the sewage treatment plants that is included in the service contract HUBER service engineer Torsten Winzer during regular annual maintenance on one of the sewage treatment plants that is included in the service contract Plant manager Frank Müller points out the great benefits customers get from HUBER service and maintenance contracts: "For us, one of the greatest benefits from a HUBER service and maintenance contract is the know-how transfer that takes place when our machines are maintained by competent HUBER service engineers. Every time they are on site our own staff can learn so much, they can watch and discuss with them decisive details of the complex technical machines and plants. We are very satisfied with the quality of maintenance we have got form the HUBER service engineers over many years already and impressed by their expert knowledge. Beyond the contractual maintenance it is very important for us that the HUBER service consultant Erwin Wagner is available for us. He provides competent additional advice and has efficient solutions to any problems and requirements on our sites. Because of the high number of plant and machines we are responsible for it is also very important for us to have a personal contact in the HUBER Service centre and thus get everything from one source. This makes it so much easier for us. In addition, the failure rate has considerably improved due to the systematic plant maintenance provided by HUBER, we have hardly had any noteworthy failures during all this time! This gives us a maximum of plant availability. Another plus factor for our decision to sign a HUBER service and maintenance contract was the extended warranty of 4 years. In summary, we must says that we are very satisfied with the services provided by the HUBER service team and can only recommend to other plant operators to make us of the same extensive benefits!"[...]

[...]Rednitzhembach, Germany HUBER was awarded the contract in early 2024 to supply and install a HUBER Rotary Drum Fine Screen ROTAMAT® Ro2 with a downstream HUBER Wash Press WAP® for renewing the STW’s screening system. These have now been in operation since the end of August 2024. Technical challenge and solution in the screen channel A particular challenge in this project was that the screen channel had to be widened from 600 mm to 1000 mm in the area of the screen basket. In order to minimise conversion time, which included demolishing the old channel and continuing to operate the sewage treatment plant with a rental screen system, a prefabricated stainless steel channel was delivered in advance and installed in the area of the screen basket. The entire project, from dismantling and conversion to commissioning, was thus completed in less than two working weeks. Initial operating experience with the new plant technology Operations managers Mr Strauß and Mr Rühl report on their experience with operating this new technology in comparison to the previously installed screening system (double bar screen with downstream screenings press): What were the main reasons for replacing the old screening system? Ultimately, there were two main reasons that led to the complete replacement of the installed system. The first reason certainly lies in the technical process of the plant. Firstly, the old screening system was unable to deliver the required throughput during mixed water peaks, resulting in the emergency bypass being activated. Secondly, the bar spacing was too large for the composition of our wastewater, so that the contamination in the other areas of the sewage treatment plant, such as floating scum on the aeration and secondary clarification tanks and screenings volume at the coarse screen in the return sludge lifting station, was much too high. Of all areas, this was most intense in the manually cleaned coarse screen (e=20 mm). Sometimes, this had to be cleaned by hand twice a day. Despite the relatively coarse bar spacing, the screenings accumulation here was almost as high as with the old 6 mm inlet screen! Another reason is the ageing equipment and the associated problems with repairing and procuring the necessary spare and wear parts. The newly installed HUBER fine screen with downstream screenings wash press has been in operation since the beginning of August 2024. What has changed fundamentally since then, in your opinion? Everything, really. There are no floating scum layers visible in the aeration and secondary settling tank or in the return sludge area. The screen separation efficiency has increased enormously. Under the same boundary conditions, approximately two to three times as much washed and dewatered screenings are now produced. The time required for manual cleaning of the coarse screen in the return sludge lifting station has been significantly reduced, from previously about twice a day with a high volume of screenings, to now once a week with a very, very low volume of screenings. A small bucket is sufficient for this. How satisfied were you with the advice received on improving the operating situation and project planning for the plant, and the work carried out? It was delivered exactly as promised – exactly as one would ideally imagine. We would like to thank everyone involved in the project, especially the Rednitzhembach sewage treatment plant employees, the plant manager Mr Strauß, and Mr Rühl, for placing their trust in us and for their excellent cooperation.[...]

[...]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 sludge has a water content of 95 to over 99%, that means it consists mainly of water. Since the disposal of such aqueous sludges is difficult and costly, and transport costs are high, these sludges have to be treated further. The following process steps are common: Sludge thickening : water content is reduced to 90 - 95%, the sludge still behaves as a liquid Sludge dewatering : water content is reduced to 60 - 80 %, the sludge is stab resistant Sludge drying : water content is reduced to less than 10%, the sludge is a dry material At least the thickening and dewatering of sludge is common practice directly at the point of origin, i.e. at the industrial plant, whereas sludge drying is only economical for very large quantities of sludge and therefore tends to be carried out in external facilities. Due to the high compaction of sewage sludge and process sludge, the dry residue (DR) is increased, transport quantities and thus transport costs are reduced to a minimum, and the sludge is optimally prepared for subsequent treatment steps. HUBER has decades of experience in dimensioning and selecting the optimum machine technology for each sludge treatment application. The HUBER Disc Thickener S-DISC , HUBER Screw Press Q-PRESS® and HUBER Screw Press S-PRESS are mainly used for industrial applications. For preliminary assessment, laboratory tests can be carried out and container-based pilot plants can be provided.[...]

[...]Current situation In industrial production, products are typically manufactured from raw materials using water and external energy. In addition to residual and waste materials, used water and not inconsiderable amounts of surplus energy in the form of waste heat are usually generated. In addition to immediate reutilisation of the heat energy within the production process and/or direct discharge from the system via separate cooling systems such as cooling towers, larger amounts of heat are also discharged via the wastewater. Increasing demands on discharge quality requirements Particularly in the case of industrial plants with direct discharge into small to medium-sized receiving waters, the discharge quality requirements are gradually being tightened under the influence of the requirements of the EU Water Framework Directive. This currently very often affects the limit values for phosphate, but increasingly also the discharge temperatures. A distinction is often even made between summer and winter discharges in order to take account of the natural temperature fluctuations of surface waters. This poses major challenges for industrial dischargers, particularly in the winter months, as the wastewater has high temperatures throughout the year due to production processes. Implementation options: HUBER energy recovery from wastewater Ideally, the necessary cooling of wastewater is carried out in such a way that the extracted thermal energy can be recovered profitably and is not lost. Unfortunately, however, direct utilisation from the wastewater is rarely possible because the wastewater is rarely clean the temperature level is comparatively low With project-specific combinations of HUBER Heat Exchanger RoWin and a suitably designed heat pump, HUBER offers a wide range of possibilities to combine the reduction of discharge temperatures required for environmental protection with regenerative heat reuse. Each application is individually tested and conceptualised. The centrepiece of every plant is the HUBER Heat Exchanger RoWin, which can be operated continuously with wastewater containing solids and grease without any problems due to its automated cleaning system. This also makes it possible to transfer the energy discharge to the inlet area of the internal wastewater treatment plant, where more favourable / higher temperature conditions usually prevail. HUBER Heat Exchangers can be used as single or group units in parallel or series connection. Depending on the existing temperatures in the wastewater, its volume and the target temperatures for discharge and internal reuse, different energy utilisation concepts can be realised. For example, in the future and already today, plant buildings can be heated (especially in winter), rinsing and washing water can be preheated, production processes can be heated, fermenters or the fermenter inlets can be preheated. In each case, the primary energy input for these processes is reduced. In this way, a valuable contribution can be made to conserving resources while at the same time protecting natural surface waters.[...]
