摘要

This study seeks to compile data on the technologies and associated costs for wastewater reuse. Reuse of reclaimed water for non-potable applications is currently the rule rather than the exception in many parts of the world. Treatment technology encompasses a vast number of options and membrane processes are regarded as key elements of advanced wastewater reclamation and reuse schemes. The identifiable wastewater reuse schemes using membrane technology worldwide have been critically analyzed in this study. Peer-reviewed journal study, conference papers and information gathered from the internet formed the basis of this review study. Different forms of potential water reuse have been identified. The available cost data was also furnished. Therefore, this study, as a whole adds to both technological and economical aspects of the knowledge-base of wastewater reuse schemes. The membrane technology appears to govern the field of wastewater reuse and this trend is likely to continue in the future. Besides the technical aspect, issues like public acceptance, economic and hygienic risks etc., should be taken into account to counter the obstacles facing implementation of wastewater reuse.
