Siemens Successfully Introduces MBR and Discfilter Technologies in European Markets

03.04.2008
Siemens Water Technologies announced today successful introduction of two innovations for reuse of wastewater plant effluent for the European market. A new membrane module enhances the performance of the membrane bioreactors (MBR).

Pleated filtration panels offer increased filtration area for disc filters. “Both innovations increase capacity of water treatment plants”, stated Roland Fischer, Head of Sales and Marketing of Siemens Water Technologies for Europe. “With the technologies, utilities can treat more water achieving better effluent quality and less footprint and energy consumption.” Both technologies will be applied in several projects in Europe, especially in Italy.

Mediterranea delle Acque in Santa Margherita Ligure and Portofino will soon install one of the largest European MBR systems located off the Ligurian Sea. Once operational in 2009, the MBR plant will be able to easily meet fluctuating water demands from seasonal tourism while producing high-quality effluent for a variety of reuse purposes. Its small footprint will consume just one-quarter the space of traditional activated sludge biological processes, also making it easier to install in an underground bunker to hide from public view.

The plant’s modular configuration will enable it to achieve a biomass concentration of up to 10 g/L while eliminating the need for final sedimentation, filtration and disinfection treatment stages. The MemJet MBR system will contain four MBR filtration cells, each consisting of 224 hollow-fiber ultrafiltration membrane modules for a combined filtration surface area of 34,000 m2. The MBR system will also lower turbidity in the treated effluent; increase removal efficiency of organic matter, suspended solids and bacteria; and produce reuse-quality water that exceeds European Union standards.

Similarly, several Italian municipalities will install 15 Forty-X disc filters from Siemens over the next few months. The disc filters will treat a total combined flow rate of 4,381 m3/h, with the number of discs ranging from one to 14 per disc filter. The disc filters will be installed at the end of the plants to meet water reuse requirements. The Forty-X disc filter uses an inside-out filtration technique. Solids are deposited inside the filtration medium, while filtrate is produced on the outside. Backwash is initiated by headloss. High-pressure spray nozzles dislodge accumulated solids, propelling them back inside the medium where they are and collected in a trough that conveys the rejected solids out of the system by gravity. As the discs are only in filtrate water, sludge removal mechanisms are unnecessary. The disc filter’s pleated filtration panels offer increased filtration area, higher operating headloss capability, water pressure-assisted seals, and trash-tolerant filter boxes – all important attributes in reuse applications.

The Forty-X disc filter uses an inside-out filtration technique. Solids are deposited inside the filtration medium, while filtrate is produced on the outside.

Forty-X and MemJet are a trademarks of Siemens or its affiliates in most countries.

Im Focus: Atoms don't like jumping rope

Nanooptical traps are a promising building block for quantum technologies. Austrian and German scientists have now removed an important obstacle to their practical use. They were able to show that a special form of mechanical vibration heats trapped particles in a very short time and knocks them out of the trap.

By controlling individual atoms, quantum properties can be investigated and made usable for technological applications. For about ten years, physicists have...

Im Focus: Images from NJIT's big bear solar observatory peel away layers of a stellar mystery

An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.

With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...

Im Focus: New Pitt research finds carbon nanotubes show a love/hate relationship with water

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.

New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...

Im Focus: Magnets for the second dimension

If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.

Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...
