Nonequilibrium Plasma Applications for Water Purification Supporting Human Spaceflight and Terrestrial Point-of-Use

Metadata Updated: May 2, 2019

Plasma technology generates powerful advanced oxidation processes (AOP’s) that attack organic contaminants and bacteria. This is achieved via a process known as mineralization where organic compounds are reduced to carbon dioxide, water, and inorganic salts. The extremely high electric fields kills bacteria by rupturing their cell membranes. Due to the extremely short duration time-scales (nanoseconds), the chemistry and physics of these processes are not well understood.

Most conventional water treatment processes are based on filtration, ozonization, UV-treatment, reverse-osmosis, and chemical consumables (e.g. chlorine). These processes have complexities due to cost, additional infrastructure, and consumables delivery.

The goal is to advance the TRL of “Plasma Pure” technology by building and testing a continuous flow 2-stage technology-enhancing plasma-reactor, capable of handling a 10 gallons/minute throughput.
