Abstract

Abstract

Fluoride pollution poses a serious threat to public health worldwide. For dispersed residential areas where high-fluoride groundwater is used as the drinking water source， electroflocculation-based defluorination is a preferable treatment option. However， this technology may have different environmental and economic impacts depending on the water supply scheme adopted， necessitating a comprehensive evaluation to identify the optimal scheme. In this study， three water supply schemes were established： centralized and undifferentiated water supply （S1）， centralized and differentiated water supply （S2）， and distributed and differentiated water supply （S3）. The life cycle environmental impacts and life cycle costs of the three schemes were compared to determine the best option. The results show that： 1） S1 has the largest negative environmental impact， with its environmental impact indicators ranging from 1.4 to 6.7 times those of S2 or S3. The environmental impact is mainly attributable to electrode consumption and electricity usage， particularly when treating large volumes of water. 2） S3 exhibits the lowest water supply cost， achieving a 62% cost reduction compared to S1. In conclusion， the distributed and differentiated water supply scheme （S3） offers both lower life cycle environmental impact and the lowest life cycle cost， making it the most advantageous option for dispersed residential areas.
