传统的（例如，混凝、絮凝和过滤）或膜过滤处理系统用于去除地下水中的有机化合物。对于带有砂无烟煤柱的常规系列，地下水的可同化有机碳（AOC）从349±127 ug/L C降至54±51 ug/L C。对于膜过滤系列，原水进水（388±126 ug/L C）和膜渗透（344±156 ug/L C）的AOC之间没有统计差异，这表明这种处理产生了生物不稳定的水。使用异养生长反应（HGR）方法也获得了类似的结果。生物稳定性方法的比较表明，HGR与AOC呈正相关（r=0。 52; P<0.0001；n=156），表明AOC只能部分解释异养细菌在水样中生长的能力。包括19个参考文献、表格和图表。

Conventional (e.g., coagulation, flocculation, and filtration) or membrane filtration treatment trains were used to remove organic compounds from groundwater. For the conventional train with sand-anthracite columns, the assimilable organic carbon (AOC) of the groundwater was reduced from 349 plus or minus 127 ug/L C to 54 plus or minus 51 ug/L C. For the membrane filtration train, there was no statistical difference between the AOC of the raw water influent (388 plus or minus 126 ug C) and that of the membrane permeate (344 plus or minus 156 ug/L C), suggesting that this treatment produced biologically unstable water. Similar results were obtained using the heterotrophic growth response (HGR) method. Comparison of the biostability methods showed that HGR was positively correlated with AOC (r=0.52; P<0.0001; n=156), indicating that AOC only partially explains the ability of heterotrophic bacteria to grow in water samples.
