[...]The aerated grit trap is a very important element in mechanical wastewater treatment. Its task is not only to reliably remove the grit from the wastewater flow but also to retain particulate lipophilic substances (grease) to prevent floatable particles from settling or overflowing in downstream treatment systems. Fine grit of a grain size ≥ 75 µm can usually not be separated by conventional aerated longitudinal grit traps as the rising air counteracts the continuous sedimentation of small particles. Very long, wide and voluminous structures are already required if you want to remove grit of a grain size ≥ 100 µm. The new HUBER Grit Trap GritWolf® we will present for the first time at IFAT 2018 sets new standards. The screen is the result of a development based on a wealth of experience in grit and grease removal gathered over many years. Steering away from space-consuming aerated longitudinal grit traps, the HUBER GritWolf® consists of an aerated chamber and a separate unaerated chamber. In the first smaller chamber the wastewater is exposed to fine-bubble aeration. Floatable particles float to the water surface where they accumulate forming bigger agglomerates. A paddle system removes the agglomerates from the grit trap surface just before the outlet. The second chamber is unaerated and equipped with so-called ‘stacked plates’. Due to the deep flow approach and the advantages of a lamella separator, the GritWolf® reliably removes 90% of the grit of grain size ≥ 75 µm. The new HUBER Grit Trap GritWolf® is available in different sizes for flow rates from 44 l/s (1 MGD) to 876 l/s (20 MGD) and requires much less space than conventional systems. The grit trap tank is usually made of concrete, stainless steel tanks for a flow of up to 175 l/s (4 MGD) are however available as an option . The HUBER GritWolf® can also be integrated into existing grit trap chambers. The horizontal grit conveyor, the lamella packages and the paddle system for grease removal are manufactured from corrosion-resistant material. The grit is removed axially from the HUBER Grit Trap GritWolf® by a time-controlled horizontal screw conveyor. Even large ‘sand dunes’ occurring under stromwater conditions (stormwater flushes) are evenly dosed into the suction area of the grit pump. Clogging in conical grit sumps or wear on scrapers are a thing of the past. A grit pump delivers the grit-water mix into a HUBER Coanda Grit Washer RoSF4 that produces clean grit in a proven way, thus perfecting the entire grit treatment system.[...]

[...]The HUBER Screw Press Q-PRESS® 280 trial equipment has been busy over the last few months. Although it has been much harder and taken longer to organise than usual, we at HUBER Technology consider ourselves very fortunate to have been able to conduct business like this during the COVID pandemic. Trial 1 The first trial was at a site in the North East of England. The site has a Population Equivalent of 61,469 and a full flow to treatment of 463 l/s and which presently uses a Gravity Belt Thickener (GBT) to mechanically thicken the Surplus Activated Sludge (SAS) produced on site, which is then mixed in 2 storage tanks with the manually decanted indigenous primary sludge. Due to varying transfer volumes and times, the ratio of SAS to Primary in the sludge tanks can fluctuate significantly. Results summary Average Incoming DS 3.97% Average Cake DS 28.48% Trial 2 This was at a WwTW site that treats effluent from a Population Equivalent of 19,615 with a dry weather flow of 202 l/s and full flow to treatment of 505 l/s. Primary industries in the catchment are food manufacturers. The treatment on site produces roughly 320 m3/d of primary sludge from the Kaldnes moving bed bio-film process, which uses aeration and floating plastic media, and around 195 m3/d of Surplus Activated Sludge (SAS). The Kaldnes sludge was considered a “tricky” sludge to subsequently process. Results summary Average Incoming DS 3.92% Cake DS using enhanced mixing 23% These results demonstrate that the Q-Press® provides a viable alternative to centrifuges with the following benefits 80% power reduction compared to centrifuge 30% reduction in poly compared to belt presses 6 fold reduction in maintenance compared to centrifuge Reliable single moving part slow rotation Reduced operator interventions Filtrate drains by gravity Removable outer case for easy maintenance For full details on the trials and more performance results please contact Rachael Harvey at Rachael.harvey@huber.co.uk[...]

[...]Ortenburg, Germany In their meeting of 21 October 2010 the market town council of Ortenburg decided in favour of the concept submitted by the engineering office Richter from Passau. In September 2013, after almost three years of planning and construction, the market town council Ortenburg put the new sewage treatment plant in Blindham into operation within an official ceremony. The new sewage treatment works is designed for 11,000 PE and provides state-of-the-art wastewater treatment. The treated effluent is discharged to the river Wolfach. The HUBER ROTAMAT® Complete Plant, type Ro5 HD with an innovative grit trap system, manages the complete mechanical wastewater on site. Several submerged pumps deliver up to 100 l/s wastewater from the underground pump sump to the above-ground installed Complete Plant so that the wastewater can flow by gravity from the Complete Plant to the secondary clarifier without the need for any additional energy. In the Ro5-HD Complete Plant not only the complete mechanical treatment of the wastewater takes place (screening in a Ro2 screen, grit separation, grease separation), but moreover, the retained pollutants (screenings, grit rap material, grease) are also treated to a large extent. With the use of this multifunctional Complete Plant the building volume for the required mechanical equipment and thus the building costs could significantly be reduced. In the medium term, also the options integrated in the Complete Plant – screenings washing and grit trap material washing – will pay off because they considerably reduce the volume of waste which requires disposal. With the HUBER ROTAMAT® Complete Plant Ro5-HD the municipality of Ortenburg not only possesses an optimal mechanical wastewater treatment solution but they also have the perfect answer to rising disposal costs now. Responsibility for a clean environment combined with cost-effective solutions plays an important role for them.[...]

[...]Whether in the development of new machines, the production of a plant or in customer support by service staff: The areas of application of digital twins affect more and more areas in the company itself, but also in its environment. In general, a digital twin is understood to be the virtual representation of a physical object that reflects its properties and behaviour at all times. Even if this provides an initial indication of what a digital twin is, the lack of a uniform definition makes it difficult to imagine what a digital twin looks like, what benefits are associated with it – and why HUBER is concerned with it. Abstract representation of a digital twin To understand the abstract representation of the dimensions of a digital twin (see diagram), it is helpful to look at the path of a machine from development to operation outlined above: In each of the stages, data is created that belongs to a product and can be assigned to its digital twin. For example, during the development of a machine, 3D models, drawings, simulation data and parts lists are created first and foremost, while in the production phase the focus is on data such as NC programmes, work and time planning or the tools used. All this data is not a recent development, but has been created since the use of software programmes in the industrial environment. In addition to the data presented, which is mainly generated and used within the company itself, there is also data that is provided to the customer. This includes information about spare parts or instructions on how to operate the machine. From the time the machine is installed at the customer's site, no new data is added to the digital twin, with the exception of service reports. This is now changing due to the advancing digital transformation. With the help of IoT technology (Internet of Things), it is possible to collect and use data from the machine in real time during operation. Advantages of digital twins for the customer and why HUBER is dealing with this The collected data enables HUBER and the operator to predict in the future when the ideal time for maintenance is, in order to avoid unplanned downtimes. Furthermore, the performance of the machine can be optimised by adapting the parameters precisely to the prevailing conditions, thus supporting the operators in operating the plant efficiently. This is not only done on the basis of the implicit knowledge of the HUBER experts, but will also be calculated in the form of simulations in the future. HUBER machines tuned to the point In addition to these direct added values, customers also benefit from the efficient further development of HUBER machines, as more and more data is available for this process. By using the insights gained from analysing the data during development, HUBER machines can be precisely matched to the existing challenges already during this phase, so that the cycle of data, information and knowledge is closed. HUBER Cloud Solution HCS: maximising customer benefits from HUBER machines A digital twin has not only one dimension, but several. The example presented shows the typical case for HUBER of a machine and its digital twin, around which an ecosystem with digital services is developed. The digital twin provides the basic framework for this. The more data it contains, the more efficiently a machine can be used. And this is exactly where HUBER Cloud Solution HCS comes in: collecting and analysing data to maximise the performance of HUBER machines during the operating phase – and as a basis for their permanent further development.
