本文讨论了一种用于去除饮用水中砷的过滤介质的开发。该介质已被证明能够将砷从700 ug/L降至2 ug/L以下。本文讨论了该介质的实验室规模、中试规模和全尺寸商业应用的结果。该介质在pH值5.0-8.0范围内有效，产生少量废物，并能抵抗背景水质基质中的常见干扰。

This paper discusses the development of a filter media for the removal of arsenic from drinking water. The media has proven capable of reducing arsenic from 700 ug/L to less than 2 ug/L. Results of bench-scale, pilot-scale, and full-scale commercial implementation of this media are discussed. The media is effective over pH range 5.0-8.0, produces a low volume of waste, and is resistant to common interferences in the background water quality matrix.
