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, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
