title: [Controlling of biological stability in drinking water by purification processes].
abstract: In a pilot scale system, the formation and removal of BDOC and AOC were compared in the pre-treatment unit, traditional treatment unit and advanced treatment unit. The experimental results indicate that the COD(Mn) removal in a traditional process plus active carbon filter system is 30% and in a traditional process plus ozone and active carbon filter system is more than 50%. The AOC contents in the effluent of a traditional process plus active carbon filter system is below 50 microg/L. The optimum process combination in the research is: traditional process plus ozonation plus biological active carbon.
