Improvement of the assimilable organic carbon (AOC) analytical method for reclaimed water

Xin ZHAO, Hongying HU, Shuming LIU, Feng JIANG, Xiaolei SHI, Mingtang LI, Xueqiao XU

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 4,   Pages 483-491 doi: 10.1007/s11783-013-0525-0

Abstract: Assimilable organic carbon (AOC) is an important parameter which determines the heterotrophic bacterialNOX are widely used to measure AOC in drinking water.The AOC values of various reclaimed water samples determined by P17 and NOX were compared with thoseIt showed that the conventional test strains were not suitable for AOC measurement of reclaimed waterG6, were selected as test strains for AOC measurement of reclaimed water.
