It is a system based on the simultaneous use of ozone and activated coal, highly effective and specialized on the treatment of water for human consumption and, besides, it is faster and more reliable than the proceedings existing in the market.
The research work, which started four years ago with the object of reducing the necessary ozone dose to eliminate different types of organic pollutants present in water allocated for human consumption, leaded to a much more complex result, as the scientists managed to prove that “they could not only reduce the dose, but also produce an increase in the speed of elimination of the organic pollutants present in water thanks to the transformation of the ozone into radicalary species of great reactivity to such pollutants”, points out the supervisor of the project and professor of the University of Granada, José Rivera Utrilla.
A more feasible and economical process
The use of ozone is one of the most effective water at present but, however, the effectiveness of the ozone is limited faced with some of the most toxic pollutants. Therefore, the researchers completed the ozonization process adding low doses of activated coal –a material with high absorbent properties both of organic and inorganic compounds which can be prepared from a variety of raw materials and industrial waste such as almond shells, olive pits, oil coke, wood, mineral coal and biomass– “which make the process technologically more viable, economically more feasible and, in addition, with the quality of increasing the effectiveness of ozone as a depurative agents”, points out professor Sánchez Polo, one of the researchers of the group.
The novelty and effectiveness of this new system for water treatment has allowed this research group of the UGR [http://www.ugr.es] to process several patents, which will be conceded in the next months, as well as the contribution of the National Plan for Research through the financing of all the research work.
Although the method has been designed to be applied on water purification process, it can also be applied on the purification of urban sewage, swimming pools and liquid effluents, like those of the textile industry, whose pollutants have centred part of the project.
Urban sewage purification to be reused on irrigation systems is other of the main applications of this new treatment system and a possible solution to tackle problems of water supply like present ones due to the drought. By means of this method, water purification and reuse would be “less expensive, faster and more effective through other systems which are being used at present”, the researchers say.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
