[...]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 [...]

[...]Innsbruck, Austria Innsbrucker Kommunalbetriebe AG (IKB) invest into a HUBER Belt Dryer BT 16. With its strategy “ from sewage works to power plant ”, IKB’s wastewater treatment plant Innsbruck sustainably produces energy and intelligently integrates it into its existing system. The aim is to further increase the efficiency of the complete sewage treatment works and make it one of the most modern plants in Europe. With its about 130,000 inhabitants, Innsbruck, the capital of Tyrol, is the fifth largest city of Austria and produces 50,000 m³ wastewater a day (peak: 145,000 m³) together with its 14 [...]

[...]Freystadt, Germany HUBER sludge treatment solution on STP Freystadt – a concept that pays off for the operators The newly installed process chain replaces the previous system with contract dewatering and its associated problems. STP Freystadt is designed for approximately 8,000 PE. The sludge on site was previously dewatered only once a year. After the implementation of the new HUBER systems, comprising a HUBER Screw Press Q-PRESS® and a HUBER Sludge Turner SOLSTICE®, the plant operators can look forward to a smoother and easier plant operation, and the disposal costs incurred by the [...]

[...]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[...]

[...]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[...]

[...]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 [...]

[...]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 [...]

[...]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[...]

[...]Magilligan, Northern Ireland HUBER Technology successfully completed the NI Water Magilligan WwTW scheme. Project Profile The Magilligan region is located on the north coast of Northern Ireland just north of the town Limvardy. This area is very popular with tourists and incorporates a Blue Flag beach at Benone as well as a significant portion of land designated as a Special Area of Conservation (SAC).It was concluded from an assessment that a single wastewater scheme for the Magilligan region would be the most cost effective solution whilst offering additional qualitative benefits for the area[...]
