本文描述了一项关于小型公共水系统（PWSs）的电话调查，该系统依赖于膜工艺的使用，以满足安全饮用水法案（SDWA）的要求。开展这项调查的目的是了解成功运行反渗透工艺生产安全饮用水的小型系统的信息。在五天的时间里，共联系了31个小型社区PWS，22个系统选择参与电话调查。这些系统都采用了以地下水为原料的膜法。数据收集包括确定要联系的工厂，收集一般操作条件的信息，以及汇编膜工艺信息。 作者提供了佛罗里达州西南部Burn Store反渗透水处理厂的总结，作为一个采用两种反渗透工艺的工厂的案例研究。根据调查结果，确定反渗透螺旋缠绕膜是最常见的元件配置。

This paper describes a phone survey of small public water systems (PWSs) which rely on the utilization of membrane processes for Safe Drinking Water Act (SDWA) compliance. This survey was conducted to develop information on small systems that were successfully operating reverse osmosis processes for the production of safe drinking water. A total of 31 small community PWSs were contacted over a period of five days, and 22 systems chose to participate in the phone survey. The systems all used membrane processes that relied on groundwater as the feed source. Data collection consisted of identifying the plants to contact, collecting information on general operating conditions, and compiling membrane process information. The authors provide a summary of the Burnt Store reverse osmosis water treatment plant in Southwest Florida as a case study of a plant utilizing two reverse osmosis processes. Based on the survey responses, it was determined that reverse osmosis spiral wound membranes were the most common element configuration.
