The elimination of biodegradable organic carbon in biological contactors :biological carbon filters

By B. Cauchi, Gilles Billen and Pierre Servais

Abstract

To avoid the risk of bacterial reviviscence in a supply network, the water produced must contain very little dissolved organic matter and particular care must be taken to eliminate the biodegradable dissolved organic carbon (BDOC) which the bacteria can consume. Biological contactors, such as granular activated carbon (GAC) filters once colonized by bacteria, will no longer adsorb DOC but the biomass they fix can be used, within a water treatment system, to reduce the biodegradable carbon fraction. Consequently, the process appreciably. affects the quality of the water produced. Following studies on pilot and full-scale plants, we have assessed the operating parameters which must be applied in the process using the following methodologies: estimation of the bacterial activity in the filter - estimation of the biomass quantities fixed in the pilot plant - the kinetics of the biological processes involved.info:eu-repo/semantics/publishe
