Publisher's Synopsis
Humic substances are naturally occurring organic material, derived from earth and plants, that cause a yellow-brown colouration to water; they are particular problem in water supplies in areas such as Scandinavia, with high humidity and temperatures around freezing, where supplies originating in moorland drainage are important. There are three main groups of reasons for treatment when such waters are to be used for drinking water purposes: aesthetic and organoleptic (sensory); health-related; and practical and economic reasons. All these factors informed a highly successful specialised conference from which these proceedings were selected. Researchers and practitioners involved with the problem of humic substances in water will find these proceedings an essential state-of-the-art reference to this subject. The 32 papers selected here cover the work of many of the world's leading experts, with a wide range of traditional and more innovative approaches to humics removal: Problem identification and overviews Coagulation-separation processes Membrane filtration processes Oxidation/biofiltration processes Sorption processes Humics removal by underground filtration Case studies.
