本研究的目的是探索限制北卡罗来纳州饮用水公用设施中卤乙酸（HAAs）形成的方法，以使其符合三卤甲烷（THM）和HAAs的拟议最高污染物水平（MCL）。探索的两种方法涉及pH调节和氯胺化。预计这两种方法都比其他方法成本更低，更容易实施，例如臭氧氧化作为游离氯的替代品，或颗粒活性炭吸附器或膜分离工艺，这两种方法都能提高DBP前体的去除率。

The objective of this study was to explore methodologies for limiting the formation of haloacetic acids (HAAs) in North Carolina drinking water utilities so that they would be in compliance with the proposed maximum contaminant levels (MCLs) for both trihalomethanes (THMs) and HAAs. The two methodologies explored involved pH adjustment and chloramination. Both of these approaches are expected to be less costly and easier to implement than other options such as ozonation as an alternative to free chlorine, or granular activated carbon adsorbers or membrane separation processes, both of which enhance the removal of DBP precursors.
