There is a great interest in preventing clogging and taste and odour problems concerning the application of granular and biological activated carbon (GAC, BAC) filters for river and reservoir water treatment. The main objective of this paper is to find links between filter removal efficiencies and the relative abundance of micro-organisms such as protozoa, diatoms and rotifers during several treatment stages. A purification manager will be able to estimate future chemical and biochemical oxygen demand (COD, BOD) removal efficiencies by looking at the development of micro-organisms in the liquid phase from the carbon bed.
