[...]Various solutions for conveying dewatered and dried sewage sludge Sludge transport plays an important role in the planning and construction of sludge drying plants. On the one hand, the dewatered sewage sludge has to be brought into the dryer and on the other hand, the fully or partially dried sewage sludge has to be transported away from the dryer. When designing a particular transport solution, important criteria include not only the required transport capacity but also the sludge properties (moist, dry, sticky, dusty,...) and the desired degree of automation. Feeding and Removing Supply and[...]

[...]From the screen to the screenings wash press – reliable and operationally safe solutions for conveying screenings HUBER offers two different solutions for providing tailor-made and project-specific conveying systems for wet and untreated screenings: Screenings transport by launder channel The screenings to be treated are discharged from one or more screens into the launder channel. Sufficient wastewater or process water is used to flush the screenings into the screenings wash press. The flushing water also serves as wash water for screenings washing. HUBER Launder Channels HLC can be [...]

[...]Screens for solids retention at sewer overflow structures for the protection of water bodies Structures with overflow are used to relieve the sewer system during rainfall. They either discharge the excess water/sewage/combined water directly into the receiving watercourse or initially store it temporarily. In practice, different types of structures can be found: Stormwater overflow: As soon as the water level in the sewer rises above a maximum permissible level, wastewater is discharged into the receiving water via an overflow channel. Stormwater overflow tank: When the rain weather begins,[...]

[...]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 [...]

[...]Targeted dosing of chemicals for better clarification performance with less consumption The use of chemicals such as acids, alkalis, flocculants or flocculation aids is necessary in many areas of wastewater treatment and sludge treatment in order to achieve the required process performance. Ideally, the right chemicals should be added in exactly the right dosage to avoid either underdosing or overdosing. While underdosing leads to reduced performance, overdosing leads to increased operating costs and can also have a negative impact on the process. The fluctuations in concentration and volume[...]

[...]Varna, Bulgaria The Bulgarian Black Sea Coast along the city of Varna with 300,000 residents is an important economic factor, especially due to its touristic potential. The European Union decided in 2002 to give aid money for the protection of the Black Sea, in particular for upgrading and building new local sewage treatment plants. The capacity of the sewage treatment plant at Varna could therefore be expanded to 450,000 PE and equipped with state-of-the-art technology. The main intention was to minimise the direct discharge of untreated wastewater to the Black Sea. They wanted to achieve that [...]

[...]Ampfing, Germany The turkey slaughterhouse Süddeutsche Truthahn AG was built in Ampfing in 2002. With 500 employees and 200 contractual fatteners, the independent Süddeutsche Truthahn AG generates an annual turnover of more than 170 million euros. The slaughterhouse Süddeutsche Truthahn AG produces approx. 800 m³ of wastewater daily. This wastewater has already been collected in the production building and treated in the wastewater building with a preliminary screen (curved screen) and a flotation system and discharged to the adjacent wastewater treatment plant. Due to continuous expansion [...]

[...]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[...]

[...]Berching, Germany The ships of the Endeavor series are the worldwide biggest mega yachts with ice class PC6. They allow expeditions to paradisiacal islands that would be impossible with conventional cruise ships. Main travel destinations are the Arctic, Antarctic and the Caribbean. The ship ‘Crystal Endeavor’ will for the first time set sail in 2020 and take its maximum 200 passengers in 100 exclusive suites to the most remote corners of the world. Two HUBER Membrane Screen ROTAMAT ® RoMem 780 units with 0,5 mm mesh size will be installed on the ship to clean the wastewater from the cabins[...]

[...]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 [...]
