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.

Micro Pollutants

The influence of natural organic matter (NOM) fouling on the rejection of micro pollutants in nanofiltration (NF) and the adsorption during granular activated carbon (GAC) filtration is investigated for a diverse group of pharmaceuticals. These pharmaceuticals were first spiked in feed waters filtered through a virgin NF-membrane and a corresponding NOM fouled membrane. The differences in rejection were never larger than 5%. The rejection of the negatively charged molecules on the fouled membrane slightly decreased and the rejection of the positively charged molecules slightly increased. These trends can be explained by a decrease of the repulsion of negative compounds and a decrease of the attraction of positive compounds by the fouled membrane. The sequential combination of NF and GAC was very effective in removing all types of pharmaceuticals. Compounds not well rejected by nanofiltration were more readily adsorbed by the GAC.
