This study is focused on reducing the concentration of assimilable organic carbon (AOC) in treated drinking water. Experiments were conducted to evaluate the efficiency of AOC removal by biological activated carbon filters (BACF) in a pilot-scale system. The results show that BACF reduces the total concentration of AOC. The concentration of AOC primarily indicates microorganism growth in a water supply network, and the amount of AOC in water is significantly reduced after BACF treatment. The predicted and measured values of AOC in output water treated by the BACF system show linear relationships, and their correlation coefficients are high. An AOC empirical equation was established by determining the relationship between water quality parameters such as total organic carbon, dissolved organic carbon, UV254, ammonia nitrogen, and total phosphorous. These findings may be relevant to conventional water treatment plants or to water distribution systems to provide treated drinking water with a high level of biological stability.
