Beschreibung

In the last decade and a half, "organics" have been a key concern in water quality research and treatment process development. Biologically originated organic materials, most notably humic substances and other decomposition products, can impair the aggregation of colloidal matter in the solids' removal stages of treatment plants. In contrast, new techniques of coagulation and co-precipitation can also improve the removal of specific organic compounds. The 288 peer-reviewed papers collected here, including the keynote overview paper, cover the major issues in organics treatment: oxidation and adsorption/filtration of organics, flocculation/coagulation processes, special aspects relating to algae and to biofilm processes. These proceedings, with their coverage of both advanced research and process developments, represent the expertise of the world's leading figures in the control of organic material in water and wastewater treatment. They should be of value to all scientists and engineers interested in organics control, whether from the perspective of fundamental research or of advanced process design.
