[...]Germany Membrane systems, especially membrane bioreactors (MBR), are wastewater treatment technologies that combine biological processes with membrane filtration. These systems are used in some sewage treatment plants instead of the conventional activated sludge process. A typical MBR system consists of a biological reactor in which microorganisms break down organic matter and a membrane filtration unit that separates the purified water from the solids. Solids separation prior to membrane filtration To ensure optimum performance, membranes must be protected from large solids. For this purpose, [...]

[...]Wendelstein, Germany Since 2008, the ZV zur Abwasserbeseitigung im unteren Schwarzachtal (Lower Schwarzach Valley Sewage Treatment Association) has been retrofitting existing relief structures with screening systems to separate floating and coarse materials. These retrofits contribute significantly to greatly improving the discharge quality of rainwater from the combined sewer system into the receiving water. Installation of a screening plant at the Röthenbacher Straße stormwater tank with overflow In the stormwater tank with overflow at Röthenbacher Straße in Wendelstein, just outside [...]

[...]Shanghai, China A total of twelve HUBER Fine Screens ROTAMAT® Ro1/2600 were supplied for the second construction phase of WWTP Zhuyu There is hardly another city worldwide that is growing with such a breath-taking speed as Shanghai, China’s boom town. But such rapid growth comes at a high price. Shanghai’s infrastructure can hardly cope. It happens time and again that the power stations can not supply enough electricity, or that even the 12 lane main highway is jammed to a stand-still. Of course, sewers and treatment plants are also under strain and the city administration is doing its best [...]

[...]Detmold, Germany The Detmold wastewater treatment plant has replaced its old step screen with a modern HUBER Multi-Rake Bar Screen RakeMax® J. The decision was made in favour of HUBER SE, who realised the entire project from start to finish – from preparing the drawings to installing and successfully commissioning the new screen system. The new HUBER RakeMax® J impresses with its high efficiency and reliability in coarse and fine screening of wastewater. Thanks to its robust design and innovative technology, it contributes significantly to improving screening efficiency and ensures the wastewater[...]

[...]Schnaittachtal, Germany The Schnaittachtal sewage treatment plant has been in operation for almost 50 years and currently employs six male and one female sewage treatment operators. For many years, the plant has relied on HUBER machines for mechanical wastewater treatment, such as the HUBER Screenings Wash Press WAP® Ro4-OS, HUBER Screw Conveyor Ro8 and HUBER STEP SCREEN. These have now been replaced by a new HUBER Rotary Drum Fine Screen ROTAMAT® Ro2 size 1600 with a 3 mm bar spacing, a HUBER Screw Conveyor Ro8 T and HUBER Screenings Wash Press WAP® SL. A quarter of a century in service In service[...]
