BHUVANDRALINGAM, S., 1994. Making GAC adsorption affordable. IN: Pickford, J. et al. (eds). Affordable water supply and sanitation: Proceedings of the 20th WEDC International Conference, Colombo, Sri Lanka, 22-26 August 1994, pp.272-274.
Two crucial uses of granular activated carbon (GAC) in water/wastewater treatment are the removal of synthetic
organic chemicals (SOCs) and the removal of natural background organic matter (BOM) that may produce undesirable disinfection by-products (DBPs). However, this treatment process may prove to be expensive if not properly designed. The objective of this paper is to provide an outline of the adsorption theory and the mechanisms responsible for adsorption process, thus identifying
the critical factors controlling the adsorption process and to illustrate their role in designing the process to be cost-competitive.
