[...]HUBER is consistently pursuing the path of digitalisation and now also offers virtual support to its customers in the Global Service business unit: With the help of augmented reality, data glasses and the new communication centre, the HUBER Remote Support Centre at the company's headquarters, the Berching-based company will be even more flexible in serving its customers worldwide in the future. The new HUBER Remote Support Centre The worldwide travel and access restrictions due to the Covid pandemic also posed some major challenges for HUBER's customers, especially as installations and commissioning of machines by HUBER service technicians, usually planned well in advance, were suddenly no longer possible. With a communication centre specially set up for worldwide remote support applications, located in the HUBER Global Service area at the company's headquarters in Berching/Erasbach, the company quickly and specifically puts an important piece of the puzzle in place to ensure communication, knowledge transfer and the availability of expertise on site. Coupled with the use of new technologies such as augmented reality (AR), HUBER effectively and successfully exchanges technical expertise remotely. In this way, many projects have already been successfully carried out and completed despite Corona and associated country-specific entry restrictions. Assembly and commi s sioning with virtual guidance from Berching For example, in addition to the mechanical assembly, the electrical assembly with final dry and wet commissioning of the GS Inima Samar Baguaçu project in Brazil was successfully guided and accompanied remotely, i.e. by service experts from Berching. Scope of delivery of this project: 3 HUBER Sludge Turner SOLSTICE® 11 and HUBER Screw Conveyor Ro8 T units with a total length of 38 metres. Cenibra Paper Mill (Brazil) – remote commissioning of a major project Considering the complexity of a complete plant and other general conditions, such as the five-hour time difference, the commissioning of the HUBER Belt Dryer BT at the Cenibra paper mill in Brazil is certainly one of HUBER's most challenging remote support projects. Cenibra operates a wastewater treatment plant that produces 54 m³ of excess sludge per hour. This corresponds to a total annual value of 78,000 tonnes of dewatered sludge, which is first pre-dewatered by 5 HUBER Screw Press Q-PRESS® 800.2 units to approx. 22 % dry residue (DR) and then dried by a HUBER Belt Dryer BT 30 to approx. 90 % DR. Smart glasses technology – from Berching to the world with data glasses With the help of smart glasses technology, the HUBER service technician's live field of vision is transmitted from on-site via so-called data glasses (smart glasses ) directly to the HUBER Global Service communication centre in Berching. Action and screen instructions are projected ad hoc onto a display built into the smart glasses to provide interactive support and bridge the distance to colleagues on site extremely effectively. Unchanged quality of HUBER service and products Not only in South America, but also in parts of Asia and Europe, HUBER was able to provide its customers with the best possible remote support during these challenging times, thus ensuring the unchanged quality of HUBER service and products. In Sri Lanka, 3 HUBER Screw Press Q-PRESS® 800 were commissioned “remotely“ and customers were extensively trained on the screw presses. A particular challenge was that, unlike in previous cases of the HUBER Remote Support Centre – also due to regional travel restrictions – no local HUBER service technician or other employees of a HUBER subsidiary were on site: the wearer of the smart glasses “at the other end of the line” was an employee of the end customer. Remote support also after Corona a trend-setting service for HUBER customers worldwide The use of augmented reality solutions is not only interesting when it comes to alternatives of an on-site service call due to current travel and access restrictions. Also in regular operations, many possibilities are offered to plan and execute service calls even faster and more cost-efficiently. Parallel to continuous use, valuable know-how is secured and a knowledge database is established and expanded so that archived operations can be used to solve comparable cases. Digital solutions save 150 tonnes of CO 2 in two years As one of the world's leading companies in the water industry, HUBER has set itself the goal of reducing environmental pollution. For every hour that HUBER service technicians do not spend in planes or cars, the company contributes to reducing the environmental impact. Thus, HUBER has already been able to reduce its carbon footprint with a saving of approx. 150 tonnes of CO 2 in the past two years by using this digital technology.[...]

The best possible screenings discharge capacity is achieved with screens that have several rakes. The number of rakes can be adjusted to suit the conditions. In addition, screenings discharge capacity can also be influenced via the discharge speed, e.g. through drives controlled by frequency converters. Which screens are particularly suitable for deep channels? Machines with a steep installation angle are best suited for such applications. This screen installation option allows the installation space to be very compact, especially in the direction of flow. Typical examples are our HUBER Multi-Rake Bar Screens RakeMax® and RakeMax® CF as well as the HUBER Belt Screen EscaMax® , HUBER Coarse Screen TrashMax® and HUBER Grab Screen TrashLift .[...]

[...]Bayonne, France The water board of the city of Bayonne supplies the drinking water for one third of the population (15,000 persons) from the valleys of Petchonea, Arquetce, Ipharager and Lapeyeren. In 2011, the Bayonne water association decided to refurbish their well shafts for drinking water supply. The refurbishment was necessary as the old bitumen coated manhole covers were leaking. The water board put the refurbishment of about 100 shafts out to tender. The tender specifications were for manhole covers including entrance ladders and installations. The cheapest offer was submitted by the construction company Miremont SEE, a specialist in refurbishing concrete shafts. The requirements concerning the manhole covers were very high. The covers had to be completely weatherproof and with safety locks and emergency escape function. The air vents are equipped with insect screens. Some covers are used for highly sensitive shafts and must therefore be attack-proof. The customer relied on our excellent quality, reliability, and experience, and the cost effectiveness of HUBER manhole covers. The order was for in total 136 manhole covers, which we delivered not all at the same time but in the course of several months. Security of supply must be guaranteed at all times. Installation was a real logistic challenge because the manholes had to be installed at difficult to access places. But due to our perfect preparation and our easy-to-install products we had no problem to promise and meet a fixed delivery date. Several employees of Miremont SEE worked on site for more than five months. HUBER manhole covers are an investment into the future. HUBER stainless steel products are acid-treated in a pickling bath and passivated. They are maintenance-free, weatherproof, attack-proof, offer state-of-the-art design, and we have made them more easier to operate: They are very easy to open due to integrated gas pressure springs. Their entrances now meet the applicable accident prevention regulations and reliably protect potable water.

[...]Nova Gorica, Slovenia HUBER received the first order for a Belt Dryer BT installation in Slovenia. Besides a number of other HUBER products, the BT 8 will be installed on the sewage treatment plant of the town Nova Gorica in western Slovenia, not far from the Italian border. The dryer is designed for an annual throughput of 9,300 t dewatered sewage sludge. In summer 2014, HUBER received the order to supply the complete equipment for mechanical wastewater treatment and sludge treatment. The mechanical equipment comprises two coarse screens type HUBER Multi-Rake Bar Screen RakeMax®, two fine screens type HUBER Fine Screen STEP SCREEN® SSF-HE with 6 mm bar spacing and three fine screens type HUBER Perforated Plate Screen ROTAMAT® STAR 1800 with 1 mm perforation. When planning the three-stage preliminary treatment system, which is to protect the downstream membrane filtration plant, the end customer relied on HUBER's positive long-term experience in the Slovenian market. Two HUBER Sludge Acceptance Plant ROTAMAT® Ro3.1 units, one HUBER Screenings Wash Press WAP® 4 and one HUBER Coanda Grit Washer RoSF4 complete the range of HUBER products installed in this complex plant. The sludge treatment plant is equipped with two HUBER Screw Press Q-PRESS® 800 units for sludge dewatering and a HUBER Belt Dryer BT 8. Both plant components ensure that the sludge from the membrane biology is first dewatered to about 20 % and then dried to > 90 % DR. The BT 8 belt dryer is operated with a flow temperature of 140 °C. The dryer thus achieves a water evaporation of just over a ton per hour on a comparatively small drying surface. The electric power that is necessary for drying is only 57 kW per kg water evaporation. This extremely low value is achieved through the dryer's unique HELIX air-flow routing system which ensures that maximum air saturation is achieved and minimizes the volume of air required for drying. This has a very positive effect on power demand as the ventilators are the major power consumers in a drying plant. Furthermore, the BT dryer is equipped with a heat recovery system which recovers the heat that is released as the vapours condensate and makes it available to be utilized for heating purposes on the sewage treatment plant. The useful heat energy generated from condensation amounts to up to 450 kW. This reduces operating costs and helps reduce CO 2 emissions.

[...]Bickenbach, Germany Advanced Wastewater Treatment: HUBER Active Carbon Filter CONTIFLOW® GAK and HUBER Disc Filter RotaFilt® Convince The Bickenbach Wastewater treatment plant (WWTP) will be the first WWTP in Hesse (Germany) to receive advanced wastewater treatment for the removal of trace substances. At the end of 2022, the wastewater treatment plant of size class 4 (35,000 population equivalents) will be extended by an ozonation system with a downstream four-line activated carbon filter stage and an upstream two-line cloth filtration as pretreatment. Among others, HUBER will supply two HUBER Disc Filter RotaFilt® units and 16 HUBER Active Carbon Filter CONTIFLOW GAK® units, commissioning is scheduled for the end of 2023. HUBER received lots for prefiltration and activated carbon filtration The overall project was put out to public tender in three lots. HUBER bid directly for the prefiltration and activated carbon filtration lots and received both contracts from the Bickenbach/Seeheim-Jugenheim Wastewater Association in November 2021 and January 2022. The two order lots include the following scope of delivery: Prefiltration 2 HUBER Disc Filter RotaFilt® 8 units Complete switchgear and control system, inlet/outlet gate valves, pumps and piping Delivery, installation and commissioning Activated carbon filtration 16 HUBER Active Carbon Filter CONTIFLOW® 50 GAK units Switchgear and control system, compressed air supply and control, piping, granulated activated carbon Delivery, installation and commissioning Pretreatment by HUBER Disc Filter RotaFilt® and subsequent activated carbon filtration by HUBER Active Carbon Filter CONTIFLOW® GAK In future, the effluent of the secondary clarifiers will be pretreated in full-flow operation at up to 300 liters per second by two HUBER Disc Filter RotaFilt® units, thus removing floating solids and impurities. This is followed by the elimination of trace substances in partial flow operation at up to 150 liters per second. This is done by oxidation in the ozone loop reactor followed by biological post-filtration and adsorption of trace substances in the 16 HUBER Active Carbon Filter CONTIFLOW® GAK units. Sensitive groundwater reservoir “Hessisches Ried”: HUBER solutions for advanced wastewater treatment reliably eliminate micropollutants “By constructing the plant for the removal of trace substances, the Bickenbach WWTP is making an important contribution to the protection of the ‘Hessisches Ried’," says Jörg Stanzel, Managing Director of the Bickenbach/Seeheim-Jugenheim Wastewater Association. “The ‘Ried’ is the largest groundwater reservoir in Hesse and provides drinking water for around two million people in the Rhine-Main region. The largest proportion of hazardous and persistent micropollutants such as pharmaceutical residues, hormones, biocides and household chemicals will be reliably retained in the future,” explains Stanzel.[...]

[...]Denitrification in the sand filter for nitrogen reduction Nitrogen is a basic building block of life and nature and, like phosphorus, is indispensable as a nutrient for all humans, animals and plants. Municipal wastewater contains various nitrogen compounds (including organically bound ammonium and nitrate). The removal of nitrogen is one of the main tasks of municipal biological wastewater treatment, because without sufficient nitrogen removal, the discharge of wastewater into receiving waters has significant negative effects on water quality and thus on flora and fauna. Denitrification Downstream Nitrogen Removal a Sand Filter Biological nitrogen removal in the course of wastewater treatment consists of the two process steps nitrification and denitrification, which take place in the aeration tank. In the nitrification process, ammonium is oxidised to nitrate; with denitrification, nitrate is reduced to elemental nitrogen, which escapes into the air. If upstream denitrification is not possible for space reasons or if the existing denitrification is not sufficient to meet the required limit values, downstream denitrification in the HUBER Sandfilter CONTIFLOW® can be applied. Denitrification takes place in the anoxic biofilm that builds up on the filter bed material of the HUBER Sandfilter CONTIFLOW ® . Denitrification does not require oxygen but easily degradable carbon. As a carbon source, e.g. methanol can be added via an external dosing station.[...]

[...]Process technology for the treatment and recycling of biowaste Saving disposal costs Treating process water and purifying wastewater Minimising residues Separating disturbing solids (plastic) Reducing operating costs The aim of biological waste treatment is to recover energy from the organic fraction of household waste as well as from organic waste, such as biowaste and food waste. For dry aerobic treatment (composting) and wet anaerobic treatment (fermentation with biogas production), good mechanical pre-treatment of the supplied biowaste is essential for the reliability and performance of the entire treatment plant. Targeted treatment of the separated solids and the fermentation residues with the right machine technology reduces disposal costs. Tailor-made treatment of process water and wastewater enables internal water cycles, leads to reduced operating costs and enables sustainable use of water resources. Most important is not only the choice of effective and efficient processes, but also their implementation with most robust and dependable machines; both are also important for the quality of the generated products. HUBER products and solutions for your requirements Organic waste is supplied in solid or liquid form, the latter being mainly contents of grease traps. For reception bunkers we supply customised HUBER Manhole Covers made of stainless steel. The supplied waste is first ground in a mill and conveyed to a pulper whereby metals are separated. In the pulper, they are soaked in hot process water, mixed and disinfected. The thus generated hot slurry is then mechanically pre-treated in a HUBER Complete Plant ROTAMAT® Ro5 Bio (special Bio version) that is specifically adapted for this task, or in a HUBER Longitudinal Grit Trap Ro6 Bio . Debris and other disturbing solids (e.g. packing and wrapping materials) are removed with an integrated Fine Screen, and heavy mineral solids (e.g. stones, grit, sand and broken glass) are separated in an aerated Grit Chamber. The removed screenings are washed and compacted, the separated mineral solids are washed and dewatered in our HUBER Coanda Grit Washer RoSF4 . The compacted screenings are incinerated as solid waste, and the washed grit is reused as construction material. In order to remove even finer solids (e.g. hair and fibres) that could clog heat exchangers and form disturbing scum layers in the fermenter, the slurry is pumped through our HUBER Sludgecleaner STRAINPRESS® before being fed to the fermenter. Within the fermenter the organic substrate is anaerobically degraded whereby biogas is produced. The biogas is used to generate power and heat in a cogeneration plant. The non-degradable fermentation residues are dewatered with our HUBER Screw Press S-PRESS . Dewatered fermentation residues can be utilized as fertilizer and for soil improvement. Wastewater that has been generated in the various treatment processes is collected, chemically conditioned and treated in a HUBER Dissolved Air Flotation Plant HDF . The HDF effluent can be used as internal process water.
