Pilot-Scale Electrocoagulation with Bipolar Aluminum Electrodes for On-Site Domestic Greywater Reuse
Publication: Journal of Environmental Engineering
Volume 131, Issue 3
Abstract
Designing a reclaimed water system provides an economically and environmentally favorable method for disposing of wastewater. However, some critical influences on on-site reclaimed water systems, such as limited building area, often limit the effectiveness of conventional treatment methods. This work established a compact and inexpensive electrocoagulation process with a capacity of to reclaim domestic greywater for human noncontact usage. The total unit cost of on-site domestic greywater reuse was , which was below the local potable water rate. Moreover, the treatment facility required an area of . Both unit cost and required area in this work are lower than those reported in the literature. The experimental results support the feasibility of the on-site reuse of greywater in high-rise buildings.
