A study on advanced drinking water treatment was conducted in a pilot scale plant taking water from conventional treatment process. Ozonation-biological activated carbon process (O-3-BAC) and granular activated carbon process (GAC) were evaluated based on the following parameters: CODMn, UV254, total organic carbon (TOC), assimilable organic carbon (AOC) and biodegradable dissolved organic carbon (BDOC). In this test, the average removal rates of CODMn, UV254 and TOC in O-3-BAC were 18.2%, 9.0% and 10.2% higher on (AOC) than in GAC, respectively. Ozonation increased 19.3-57.6 mu g Acetate-C/L in AOC-P17, 45.6-130.6 mu g Acetate-C/L in AOC-NOX and 0.1-0.5 mg/L in BDOC with ozone doses of 2-8 mg/L. The optimum ozone dose for maximum AOC formation was 3 mgO(3)/L. BAC filtration was effective process to improve biostability.
