[...]United Utilities, Warrington, England Background In 2017, United Utilities started work on a four-year improvement project at Blackburn and Darwen WwTW. This work included: Extending the current works at Blackburn WwTW to construct new tanks, buildings and improve the treatment process. Taking existing wastewater flows from Darwen WwTW through to Blackburn WwTW by installing a new connecting pipe and upgrading the existing tanks. Constructing new storm tanks and new pipeline to transfer wastewater to Blackburn WwTW from Nabs Head WwTW. Blackburn WwTW treats principally domestic crude sewage from[...]

[...]Plymouth, England Background Site operators at Plymouth Central STW wanted a more reliable and less labour intensive option to de-watering than a centrifuge. South West Waters requirements were lowest WLC, low operator attendance and simple operation South West Water had been looking at alternative dewatering technologies with lower TOTEX to potentially replace existing veteran centrifuge assets and tasked preferred contractor Kier to offer solutions for the Plymouth Central and Maer Lane WwTWs. Plymouth Central serves a Population Equivalent of around 320,000 and, being on a coastal port [...]

[...]The advanced treatment of sewage sludge or industrial residual sludge is increasingly gaining in importance also for industrial customers. Whereas, until recently, the common strategy was to pass the sludge on to disposal companies at low costs, this has now become more and more complicated, difficult and especially more expensive due to the modified and now more stringent German Fertilizer Regulation and Waste Sewage Sludge Ordinance and because of the generally increasing costs in the disposal industry. Therefore, industrial customers increasingly concern themselves with strategies how to additionally[...]

[...]Freystadt, Germany Due to the new regulations and legislation for sewage sludge, disposal costs have doubled for many sewage treatment plants or increased to far more than 100 € per ton original substance. The reason for the cost increase is that the standard solution for meeting the requirements of the new legislation is sludge incineration. Incineration capacities are however unequally distributed and exploited to a large extent, and transport ways have become longer on many sites. Disposal costs can be reduced if the sludge volume is reduced through drying. The Bavarian municipality Freystadt [...]

[...]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[...]
