毫无疑问，膜技术在饮用水处理和病原体保护方面是未来的潮流。此外，膜系统每天都在变得更具成本效益，考虑到生命周期成本，低压膜通常比传统水处理技术更便宜。对于大多数地表水系统，最合适的膜应用是低压膜，包括微过滤和/或超滤。低压膜的一个共同问题是其去除溶解有机物的能力以及相应的膜材料有机污染。考虑到第1阶段消毒剂/副产物消毒（D/DBP）规则的通过，有机物的去除对于许多水系统至关重要。 因此，本文讨论了HDR Engineering，Inc.和北卡罗来纳州瓦德斯博罗市进行的一项并排试点研究的结果，以评估低压膜用于扩建其水处理厂的可行性，以及是否符合第1阶段D/DBP规则。包括表格，如图所示。

There is little question that membrane technology is the wave of the future in terms ofdrinking water treatment and pathogen protection. In addition, membrane systemsare becoming more cost-effective each day, and when life-cycle costs are considered,low-pressure membranes are often less expensive than traditional water treatmenttechnologies.For most surface water systems, the most appropriate membrane applications are low-pressure membranes, including micro- and/or ultrafiltration. One common concern withlow-pressure membranes is their ability to remove dissolved organic matter and thecorresponding organic fouling of the membrane material. The removal of organicmaterial is critical for many water systems considering the passage of the Stage 1Disinfectants/Disinfection By-Product (D/DBP) Rule.Accordingly, this paper discusses the results of a side-by-side pilot study performed byHDR Engineering, Inc. and the Town of Wadesboro, NC to evaluate thefeasibility of low-pressure membranes for an expansion of its water treatment plant andfor compliance with the Stage 1 D/DBP Rule.
