- Abstract
This article compared the three methods for measuring biodegradable dissolved organic carbon (BDOC) in water. Here, we evaluate the comparability and reproducibility of methods. In order to allow a comparison between the results and to perform statistical analysis of the data, three types of water (drinking water, river water and synthetic sample) were analyzed by using suspended biomass inoculum, fixed biomass inoculum in the batch test and fixed biomass inoculum in the two columns system. Our results showed that the precision of various BDOC methods was similar (4-26%) across a broad range of BDOC (from 14% to 19% of total dissolved organic carbon (DOC) in the river water and from 45% to 59% of total DOC in the drinking water). We recommend two columns method for future studies.
