The Biowall Field Test Analysis and Optimization
A residential botanical
air filtration system (Biowall) to investigate the potential for using
phytoremediation to remove contaminants from indoor air was developed. A full scale and functioning prototype was
installed in a residence located in West Lafayette, Indiana. The prototype was integrated into the central
Heating, Ventilating, and Air Conditioning (HVAC) system of the home. This
research evaluated the Biowall operation to further its potential as an energy
efficient and sustainable residential air filtration system.
The main research effort began after the Biowall was installed in the residence. A field evaluation, which involved a series of measurements and data analysis, was conducted to identify treatments to improve Biowall performance. The study was conducted for approximately one year (Spring 2017-Spring 2018). Based on the initial data set, prioritization of systems in need of improvement was identified and changes were imposed. Following a post-treatment testing period, a comparison between the initial and final performances was completed with conclusions based on this comparison.
The engineering and analysis reported in this document focus on the air flow path through the Biowall, plant growth, and the irrigation system. The conclusions provide an extensive evaluation of the design, operation, and function of the Biowall subsystems under review.
