本文简要介绍了scwd²海水反渗透（SWRO） 海水淡化中试研究，提供了9个月的海水淡化中试结果总结 并比较了不同预处理系统的碳足迹 替代预处理系统。本文将碳足迹定义为 每年温室气体（GHG）排放的当量二氧化碳（单位:公吨）。

This paper briefly describes the scwd² seawater reverse osmosis (SWRO) desalination pilot-scale study, presents summary results from 9 months of pilot tests on the alternative pretreatment systems, and compares the carbon footprint of the alternative pretreatment systems. In this paper, carbon footprint is defined as the equivalent carbon dioxide in metric tons per year of greenhouse gas (GHG) emissions.
