To supply safe, good-quality tap water, Osaka Municipal Waterworks Bureau (OMWW) introduced an advanced water treatment system that incorporates ozonation and granular activated carbon (GAC) treatment into conventional treatment processes. By March 2000, all water purification plants in Osaka City were equipped with advanced water treatment facilities. This new treatment system has successfully removed odours and flavor and reduced trihalomethane. GAC treatment, the last stage of the water treatment, plays a vital role in removing organic matter in water, in conjunction with ozonation. However, GAC performance changes over time. To optimize the GAC effect, it is essential to conduct proper GAC management based on a thorough grasp of the change patterns of GAC performance. To determine GAC's water treatment capability, we analyzed data on 69 water quality items; obtained from past plant tests and chemical substance addition experiments using GAC actually used in the purification plants. Analysis revealed the deterioration patterns and time of GAC performance. By considering physical properties and economic factors as well as deterioration patterns of GAC performance, it is possible to establish an optimal GAC management system. This paper describes the findings obtained from the study on GAC water treatment performance conducted by OMWW.

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.

A K.pneumoniae strain, isolated from a water treatment system, was tested in growth measurements for its ability to multiply at substrate concentrations of a few micrograms per liter. The organism multiplied on mixtures of carbohydrates and amino acids at a substrate concentration of 1 µg of C of each compound per liter. Tests with individual compounds revealed that especially carbohydrates were utilized at low concentrations. The Ks values obtained for maltose and maltopentaose were 53 µg of C/l and 114 µg of C per liter, respectively. The significance of the growth of K.pneumoniae at low substrate concentrations is discussed.
