RHELP (Regenerative High Efficiency Low Pressure) Air Purification System
Abstract
This project aims to develop a RHELP (Regenerative-High Efficiency-Low Pressure) air purification system using a novel ceramic nanofiber on silicon carbide in a microwave oxidizer that can effectively decontaminate air containing aerosolized chemical and biological (CB) agents. Nanofibermats of several materials were designed and fabricated using electrospinning process. Physical filtration testing showed performance (filter quality) exceeding military HEPA requirement. Multiple layers were found to have better filter quality than single layer of the same thickness. Biological agent testing showed effectiveness of microwave irradiation to deactivate a wide range of biological agents. System performance can be further enhanced by lowering face velocity during periodic microwave irradiation to minimize heat loss. Chemical agent testing showed excellent regeneration but destruction of the agent needs further improvement.
