本研究的目的是确定天然有机物（NOM）和三卤甲烷形成潜力在选定佛罗里达水域的分布，作为表观分子量（AMW）的函数，并确定NOM在形成三卤甲烷中的反应性是否也是AMW的函数。然后，通过比较被测水的AMW分布和所考虑膜的标称分子量截止规格，可以得出有关膜处理效果的结论。

The objectives of this study were to determine the distribution of natural organic matter (NOM) and trihalomethane formation potential in selected Florida waters as a function of apparent molecular weight (AMW) and to determine if the reactivity of NOM in forming THMs is also a function of AMW. Conclusions regarding membrane treatment effectiveness may then be drawn by comparing the AMW distributions of the waters tested and the nominal molecular weight cutoff specifications of the membranes under consideration.
