Scientists of the UGR develop a new method to purify water based on the simultaneous use of ozone and activated coal

09.10.2006
A research team of the University of Granada has developed a new method of water purification which has aroused the interest of several and research centres such as the Swiss Institute for Environmental Science and Technology and the US company Carole Engineers.

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.

Im Focus: First evidence on the source of extragalactic particles

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...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

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...

Im Focus: Breaking the bond: To take part or not?

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...

Im Focus: New 2D Spectroscopy Methods

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....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

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...
