Advanced Wastewater Photo-oxidation System, Phase I

Metadata Updated: May 2, 2019

Pioneer Astronautics proposes an advanced photocatalytic oxidation reactor for enhancing the reliability and performance of Water Recovery Post Processing systems aboard crewed spacecraft. This novel technology, called the Advanced Wastewater Photooxidation System (AWPS) is designed to oxidize and remove recalcitrant aqueous organic constituents in the water recovery post processing system under ambient temperature and pressure conditions. The basis of the innovation is the combination of high brightness and long lifetime UV LED light sources with efficient geometric illumination of a highly active photocatalyst immobilized on a high surface area support. This combined approach leads to numerous performance benefits including high conversion efficiency, low temperature and pressure operation, compact footprint, high reliability and low crew maintenance, and decreased equivalent system mass (ESM). The Phase I effort will clearly demonstrate the feasibility of these concepts by mineralization of polar water soluble organics and organosilanol constituents under long duration testing. Data from the Phase I will lead to a prototype scale-up of the device in Phase II. Development strategies for the Phase II device include component design verification testing and determining optimum reaction conditions. Long duration performance tests will validate the reactor design, and establish the technology applications in space and commercial markets.
