佐治亚州霍尔县是亚特兰大大都会地区增长最快的地区之一，该县正在开发供水系统以满足新的增长。作为该项目的一部分，CH2M HILL和该县对各种处理工艺进行了评估，以向其客户提供经济高效的优质水。本文重点介绍了强化混凝、粗化澄清器和膜相结合作为可行技术的结果和实施，以满足第I阶段污染/消毒副产物规则（D/DBPR）要求、地表水处理规则（SWTR）、临时强化地表水处理规则（IESWTR）和未来病原体灭活/去除要求。将讨论初步试验要求和结果，以验证推荐工艺的有效性，并将成为一个有用的工具，不考虑其他具有类似水质特征的地表水厂的拟议工艺。 本文还将回顾将粗滤澄清器与低压微滤/超滤（MF/UF）膜结合作为地表水厂预处理步骤的有效性。试点测试将于2001年1月至2001年4月进行；因此，在编写本手稿时无法获得实际的试点测试结果，但将在演示时提供。包括表格、数字。

Hall County, Georgia, one of the fastest growing areas in the metropolitan Atlanta Region isdeveloping a water supply system to meet new growth. As part of this project, CH2M HILL andthe County have evaluated various treatment processes to provide cost effective, high qualitywater to its customers. This paper focuses on the results and implementation of the combinationof enhanced coagulation, a roughing clarifier and membranes as viable techniques to meet Stage IDisinfectant/Disinfection By-Products Rule (D/ DBPR) requirements, the Surface WaterTreatment Rule (SWTR), the Interim Enhanced Surface Water Treatment Rule (IESWTR) andfuture pathogen inactivation/removal requirements. Pilot testing requirements and results will bediscussed to verify the effectiveness of the recommended processes and will be a useful tool inconsidering the proposed process for other surface water plants with similar water qualitycharacteristics. The paper will also review the validity of using roughing clarifiers as apretreatment step in conjunction with low pressure microfiltration/ultrafiltration (MF/UF)membranes for surface water plants. Pilot testing will be conducted January 2001through April 2001; therefore, actual pilot testing results are not available at the time thismanuscript is being prepared, but will be provided at the presentation. Includes tables, figures.
