New thermal drying system from Siemens to help minimize biosolids in Poland’s fourth largest city

13.09.2010
The city of Wroclaw, Poland, will be installing a thermal drying system from Siemens Water Technologies at its wastewater treatment plant (WWTP) that serves approximately 1 million people in the metropolitan area. Comprised of four Ecoflash thin layer dryer lines, the 10 tons/hr evaporation capacity drying system will reduce the city’s daily municipal biosolids volume from 320 tons/d to 109 tons/d. The dryers will become operational in 2011.

Poland produces approximately 1 million tons of biosolids per year – a little more than a third of which is municipal. Almost half of that is currently sent to landfill. With both biosolids volume and landfill costs expected to increase significantly over the next few years, alternative disposal methods such as incineration and drying are becoming of growing interest.


Some advantages to using the Ecoflash dryer include high energy efficiency; minimal environmental impact; and flexible, simple, and safe operation. Picture: Siemens AG

The Siemens Ecoflash thin layer dryer is designed to dry biosolids using either diathermic oil or saturated steam. Inside the drying chamber, a rotor equipped with adjustable pitch blades operates at high speed. The wet biosolids are fed into the drying chamber by a dosing unit (metering pump) and centrifuged by the rotor, into a thin film layer, on the drying chamber wall. The blades of the rotor move the biosolids through the process in a dynamic and turbulent action, creating an energy-efficient evaporation process. A counter current of air removes the evaporated water from the dryer and helps to cool the dried biosolids prior to them being discharged.

The Siemens’ thermal drying system was selected because of the technology’s high reliability and safety, small footprint, low maintenance, and minimal operator attention required. Additionally, integrated energy recovery makes the thermal energy requirement particularly low. Other advantages include high energy efficiency; minimal environmental impact; short product retention time and agriculture-grade pathogen reduction.

Ecoflash is a trademark of Siemens and/or its affiliates in some countries.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
