DOWNLOAD EBOOKRefractory organic substances (ROS) are an essential part of the biogeochemical carbon cycle. Wherever there is life on earth, there will also be ROS in the form of poorly biodegradable leftovers of organisms and as a source for new life. Furthermore, it is now beyond doubt that ROS are closely related to the carbon intensity identified as one of the driving forces in the dynamics of green house gas emission, such that ROS play a key role in sustainable development. 'Refractory Organic Substances in the Environment' provides the results of six years of top-priority research, funded by the Deutsche Forschungsgemeinschaft (DFG). This research program investigated the structure and function of ROS in different parts of the environment, from a chemical, physical, biological, and soil scientific point of view. It included the first systematic study of a set of reference samples from Central Europe, originating from a bog lake, soil seepage water, groundwater, and from the wastewaters of a brown coal processing plant and a secondary effluent. Thus, this work not only highlights the structural features obtained from the application of advanced analytical tools, but also the function in anthropogenically influenced aquatic systems and soils. Of special interest to students and researchers in life sciences.

DOWNLOAD EBOOKAn experimental study of an advanced chemical oxidation system was carried out to determine the rates of oxidation of difficult to oxidize, 'refractory', chemical species which are not removed by conventional secondary treatment plus carbon absorption. One representative was chosen for this investigation from each of the five types of refractories in municipal wastewater, alcohol, acid, amino acid, fatty acid, and polyhydroxyl alcohol. A refractory index scale was established to provide a means of comparing the resistance to oxidation of refractory compounds. All of the refractories investigated benefited by at least an order of magnitude increase in reaction rate when UV and ozone are used over that obtained when ozone alone is used. The work proves the technical feasibility of the process concept and provides preliminary data on mass transfer, reaction rate, and ozone autodecomposition for pilot scale work.
