近年来，膜技术已成为寻求遵守美国环境保护局（USEPA）饮用水法规的公用事业公司的一种可行的替代处理方法。这类技术变得更具吸引力的一个原因是，与传统处理系列相比，它有可能使用更少的单元工艺来满足微生物和消毒副产品的监管要求。纳滤、超滤和微滤在去除消毒副产品前体方面的有效性尤其令人感兴趣，因为预期会有更严格的法规。 包括11个参考文献、表格、图表。

Membrane technologies have emerged in recent years as a viable treatment alternative for utilities seeking to comply with new and pending US Environmental Protection Agency (USEPA) drinking water regulations. One reason this type of technology has become more appealing is that it has the potential to meet regulatory requirements for both microbes and disinfection byproducts using fewer unit processes than conventional treatment trains. The effectiveness of nanofiltration, ultrafiltration, and microfiltration for removing disinfection byproduct precursors is of particular interest in anticipation of more stringent regulations.
