[...]Counteracting rising operating costs and quality requirements through digital solutions Identify and exploit optimization potentials through data evaluation HUBER Cloud Solution HCS as a basis for future additional services The challenges in wastewater treatment are constantly growing and the adequate treatment of wastewater and sludge at wastewater treatment plants is becoming increasingly difficult. The reasons for this are the increasing demands on the treated wastewater and sludge combined with dwindling personnel resources and rising costs for energy and operating materials. As a result, the[...]

[...]The efficient flocculant mixer achieves a significant reduction of operating costs Conditioning of the sludge to be processed with polymeric flocculants is a precondition for the mechanical dewatering of sewage sludge. The focus is typically on the optimal flocculant dose as this is the factor that influences directly the dewatering results and flocculant consumption, and thus the largest portion of the operation costs. Turning the attention to sludge conditioning as the determining process step for dewatering, it becomes apparent however that also the mixing intensity and flocculant solution [...]

[...]Bad Orb, Hessen, Germany The further developed HUBER Screw Press Q-PRESS® was presented for the first time at IFAT 2016. The first units were installed soon and have meanwhile been in operation for more than a year. Now, it is time to review the operational experience gained on site against development targets. In April 2016, a new sludge dewatering system for STP Bad Orb was put out to tender to replace a chamber filter press. Extensive on-site testing was done before in 2015. During the tests, the screw presses turned out to be the most suitable dewatering solution. HUBER offered the newly [...]

[...]As the original designer and manufacturer of the world recognised and respected HUBER STRAINPRESS® pressurised sludge screen, it has been increasingly interesting to us to see the number of different applications where the STRAINPRESS® has been utilised and requested. From its original launch into the market in 1990, with its cast steel casing, chain-drive motors and old stuffing box seals, the unit then underwent a period of innovation in 1999 and the latest design was launched in 2000. The modifications included items such as the whole casing now being manufactured and supplied in 304L stainless[...]

[...]Minworth, England A HUBER Technology Wastewater Case Study at Minworth STW HUBER Technology recently completed a project at one of the largest inland sewage treatment works in the UK, Minworth STW. Minworth serves a population equivalent of 1.75 million from Birmingham with full flow to treatment of 1,070Ml/d. The works treats sludge arising from a population equivalent of 2.3 million which is made up of indigenous sludge plus imported sludge from the nearby Coleshill STW and various works in Staffordshire and north Warickshire. Good early engagement from all the concerned parties helped [...]

[...]Redesign reduces the hazard potential Whether we develop new products or redesign existing machines, we always do this considering also the safety aspects that are important to minimise the hazard potentials when handling our products as required by the Machinery Directive. How important it is to pay special attention to product safety could be seen only last year on a competitor’s solar sewage sludge dryer installation in Bavaria where a tragic accident happened. This was even more reason for us to once again look very thoroughly at our safety systems and further improve them. When we recently[...]

[...]Niebüll, Germany 2 HUBER Complete Plant ROTAMAT® Ro5 units for 100 l/s on STP Niebüll in Northern Germany Those who know the regions up in the north will know where the town Niebüll is located: It is a holiday destination in the northernmost part of Germany at the North Sea from where also the motorail train crosses the Hindenburg Dam to the village Westerland on the island of Sylt. These special circumstances naturally played a major role for the engineering office Ivers in Husum when planning the preliminary wastewater treatment stage on STP Niebüll. It had to be taken into account that the [...]

[...]Isle of Man, Great Britain The first HUBER Belt Dryer BT installation in Great Britain went officially into operation recently. On the Isle of Man, up to 12,775 t sewage sludge per year will efficiently be dried from now on. HUBER received the order to build a belt dryer on the Isle of Man at the beginning of 2015. The customer wanted to reduce the energy expenditure for sludge drying and the resulting high disposal costs. The HUBER BT 16 achieves this most impressively. The sewage treatment plant of the town Douglas does not have any sludge digestion facilities. There is therefore no exhaust air [...]

[...]The regular inspection of installations is an important aspect not to be underestimated where drinking water and wastewater structures need to be maintained as valuable elements of our supply and disposal networks. Regular inspections are the only way to ensure the plants and their peripherals can safely be operated a long time. It is of fundamental importance to early identify defects, damage and weak points by regular inspection so that these can be expertly eliminated as soon as possible. The risks of continuing with run-down equipment are not to be neglected, especially not in the field of drinking[...]

[...]Novelty – HUBER Sludgecleaner STRAINPRESS® 420 With nearly 1000 produced machines, the HUBER Sludgecleaner STRAINPRESS® 290 is one of the most proven HUBER products. To complement or as an alternative to fine screens installed in channels, the STRAINPRESS® permits the separation of solids even from closed pipeline systems. In contrast to conventional screening systems, the STRAINPRESS® not only separates solid material, it also dewaters the material before discharging it. Typical screen perforations used for screening primary sludge are 3 mm or 5 mm, with the screenings being dewatered to dry[...]
