Constructed wetlands and solar-driven disinfection technologies for sustainable wastewater treatment and reclamation in rural India: SWINGS project

Abstract

The largest wastewater treatment plant consists of a high-rate anaerobic system, followed by vertical and horizontal subsurface flow constructed wetlands (HFCW) with a treatment area of nearly 1900 sq m and a final step consisting of solar-driven anodic oxidation and ultraviolet disinfection units allowing direct reuse of the treated water. and even act as a revenue generator. The effluent of the HFCW is collected in a 1.8 m deep well, from where about 10% of the final effluent is pumped and disinfected using the two solar-powered units. The implementation of the systems under the umbrella of the SWINGS project will provide opportunity to tes advanced CW configurations operating to meet local needs.
