Biofilms consisting of a matrix of exopolysaccharide and microorganisms developed over granular activated carbon (GAC) enhance metal uptake from solution several times more than that achieved by GAC alone. By specifically employing GAC, there is also the opportunity of developing biofilm/GAC systems that can both entrap metals and also adsorb, and ultimately degrade, polluting organic residues such as pesticides. Targets for this type of process could be dump site leachates, mine tailings and other industrial wastes. The conditions under which the biofilm is developed, including pH and temperature have, therefore, been studied in terms of subsequent influence on metal bisorption.

Iron and manganese oxides/granular activated carbon composite (GACFM) was prepared via a chemical coprecipitation route, followed by a heat treatment at elevated temperature. The as–prepared GACFM was characterized by X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The main iron and manganese oxides actually present in the composites were mainly composed of Fe3O4 ,Mn3O4 and (FeO)x(MnO)1-x. The adsorption and catalytic properties of GACFM and some conditions effects such as H2O2, pH , temperature and CO32- were studied for the removal of 2,4,6-trichlorophenol (TCP) from aqueous medium. The adsorption of TCP on GACFM obeyed the Freundlich isotherms. When the initial concentration of H2O2 was 0.4mg/L , 5mg/L TCP removal rate was maximum on the GACFM. The treatment of TCP could be carried out at initial pH under 7.0. CO32- can scavenge •OH in solution and decreased TCP removal. In the whole, GACFM was satisfactory absorbent and catalyst for the removal of chlorophenol from water.

In Harelbeke a Water Treatment Plant with a capacity of 15,000 m3/day, using Schelde river water has been in operation since April 1995. The treatment process comprises nitrification, dephosphatation by direct filtration, storage into a reservoir, direct filtration, granular activated carbon filtration and disinfection. The design of the three-layer direct filters was based on pilot experiments. The performance of the plant during the five years of operation is discussed. It was found that the removal of atrazin by activated carbon depends on the water temperature.
