3. International conference on oxidation technologies for water and wastewater treatment. Special topic: AOP's for recycling and reuse

With the increasing pressure on a more effective and sustainable use of water resources, those water treatment technologies become more and more important which will allow for a recycling of wastewater for agricultural and/or industrial purposes. The so-called advanced oxidation processes (AOP's) belong to these technologies as they offer the potential of a complete conversion of the water pollutants to carbon dioxide, water and mineral salts. Despite the progress that has been achieved in understanding and applying AOP's, the most significant disadvantages of the oxidation technologies are the high investment and operating costs. As these technologies are the high investment and operating costs. As these technologies are based on radical reactions, more effective means of producing radicals and a deeper insight in the reaction pathways will be the key for generating radicals at lower costs as well as choosing the optimum process conditions and defining the applications where AOP's are most competitive. Two national, three international conferences with the publication of their papers in water science and technology (1997 and 2001) as well as the foundation of the IWA Specialist Group on AOP's in 2001 demonstrate the success and the necessity of this conference series. It is designed to bring forward the most recent advances in the fundamentals as well as the development and the application of AOP's especially in the field of water recycling reuse. It will help to disseminate new achievements in these areas and to identify future research and development needs. The increased number of interesting papers submitted will be the basis for a successful, fruitful and hopefully critical conference in Goslar. (orig.)
