Subproducts resulting from disinfecting drinkable water

09.09.2005


For his PhD thesis, Unai Iriarte Velasco analysed strategies for reducing levels of subproducts from the disinfection of drinkable water and their application in optimising the functioning of water treatment plants.



The thesis, recently presented at the University of the Basque Country, centres on the treatment of drinkable water. Currently it is known that the chlorine employed as disinfectant reacts with the natural organic material present in surface water. This interaction is responsible for the presence of certain undesirable substances known as disinfection subproducts. In fact, current legislation includes some of these disinfection subproducts amongst their criteria for the first time. The general aim of the thesis was to evaluate the factors that favour the formation of these subproducts and thus reduce the levels of exposition derived from the consumption of drinkable water.

The thesis has managed to establish the influence of the physicochemical characteristics of the supply water. The efficacy of the various treatments available was studied and new tools for the on-line control of the water purification plants have been developed. Moreover, according to the author, a higher quality product is not obtained using a greater amount of disinfectant.


Notable amongst the conclusions is the need to prepare made-to-measure water purification treatments, depending on the physicochemical nature of the supply water of the plant. The results obtained will be used to establish guidelines to follow in order to enhance existing purification treatments, as well as the design of future treatment plants. Companies such as PRIDESA and CETOLAR have already shown interest in the research.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
