Solar Optics-based Active Panels (SOAP) for Photocatalytic Greywater Treatment: Design and Kinetics [BPN680]
Water scarcity is projected to affect 1.8 billion people in the world by 2025. Due to the
dramatic population growth of urban areas, the imminent water crisis demands efficient greywater
treatment in new housing solutions. To address this need, we are developing a prototype of Solar
Optics-based Active Panels (SOAP), which allows us to test the photocatalytic treatment of
greywater using sunlight and immobilized titanium dioxide nanoparticles. The expected outcome of
this research will be a prototype SOAP reactor that demonstrates fast inactivation of representative
contaminants of greywater (e.g., coliform bacteria and organic pollutants). The SOAP reactor's
optical, thermal, and thin-film flow performance will be experimentally characterized across
critical reactor design parameters. Those parameters producing optimal photocatalytic treatment
kinetics in a variety of simulated solar conditions will be identified. The prototype SOAP reactor
will present a promising platform for integration of nano- and micro-technologies into point-of-use
water treatment in global urban environments.
