José Manuel Poyatos Capilla, researcher from the Department of Civil Engineering of the University of Granada [http://www.ugr.es], is the main responsible for this work, which has been directed by professor Ernesto Hontoria García, director of the Superior Technical Engineering School of Roads, Channels and Ports of the UGR [http://www.ugr.es]. Research of Prof. Poyatos is particularly interesting if the current global drought is taken into account, as well as the lack of space many municipalities have when the number of inhabitants grows, which makes it impossible to enlarge their water treatment plants.
Prof. Poyatos has used a new technology based on membrane bioreactor systems which makes it possible to shorten the water clarification process (by which active mud is separated), eliminating the stage known as “secondary decanting.” The structure of every plant currently has four stages: pre-treatment, primary decanting, biological reactor and secondary decanting. A tertiary treatment can also be added whenever water is used for irrigating.
An advantageous system
Research carried out at the UGR [http://www.ugr.es] could reduce the size of the biological reactor between 40 and 60%, and would completely eliminate secondary decanting. “In the future – explains the researcher –- we could even suppress the primary decanting stage.” In exchange, scientists from Granada have included a “biological processes” section in their wastewater treatment plant, which could make it possible to separate water from active mud by a membrane filtration process.
This researched and optimized system makes it possible to treat a larger flow of water in a smaller purifier, “and its building would involve a less expensive construction.” Installation is therefore much cheaper than installation of plants with tertiary treatment, and it also makes it possible to use the water immediately after it has been biologically treated.
The work of José Manuel Poyatos, which has been partly carried out at the University of Cranfield (England), is the first with these characteristics carried out in Spain. Results of his research have been published in prestigious journals such as ‘Journal of Environmental’ and ‘Microbiology&Biotecnology’, and they were also presented at the Ibero-american Congress on Membrane Science and Technology. They will be soon presented at two international congresses of the IWA (International Water Association).

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
