在本文报告的研究中，比较了在大多数饮用水系统典型的低营养环境下形成的生物膜的比生长率和碳去除率。将暴露于游离氯消毒的生物膜的测量参数与不含氯的平行对照情况下的参数进行比较。使用三种主要基质组和一种混合物进行单独的实验，每种基质混合物代表一种主要的天然生物降解有机碳。包括42个参考文献，表1。

In the research reported here, specific growth and carbon removal rates were compared for biofilm developed under low nutrient environments typical of most drinking water systems. Measured parameters for biofilm exposed to free chlorine disinfection were compared to those from a parallel control situation without chlorine. Separate experiments were performed using three primary substrate groups and one mixture, each substrate mix representing a major class of naturally occurring biodegradable organic carbon. Includes 42 references, table.
