一些易受合成和挥发性有机化学品污染的饮用水系统的运营商已表示有兴趣对现有处理厂进行改造，以包括颗粒活性炭（GAC）吸附。在评估GAC治疗方案时，一个重要的考虑因素是检查成本因素。本文介绍了不同系统尺寸和碳床寿命范围内各种应用的初步成本估算。研究了与使用钢制压力和混凝土重力接触器的后滤式吸附器相关的成本，以及与流化床、红外和多炉膛再活化技术相关的成本。包括8个参考文献、图表和表格。

Operators of several drinking water systems that are vulnerable to contamination by synthetic and volatile organic chemicals have shown interest in modifying existing treatment plants to include granular activated carbon (GAC) adsorption. An important consideration in the evaluation of GAC treatment alternatives is the examination of cost factors. This article presents preliminary cost estimates for various applications over a range of system sizes and carbon bed lives. Costs related to postfilter adsorbers using steel pressure and concrete gravity contactors are examined, as well as costs associated with fluid-bed, infrared, and multihearth reactivation technologies. Includes 8 references, figures, tables.
