Nano Ceramic Sterilization Filter

Filters don't exist that are capable of removing virus and bacteria at high enough flow rates to be practical either for space systems or for domestic consumption. In Phase 1 we demonstrated feasibility that our nano ceramic fiber filter could produce sterile water at high flow rates. In Phase 2 we propose to develop performance data on such filters that would provide NASA with the capability for sizing such filters for AWRS for diverse missions. The tasks also include improving the strength of the filters, providing them with biocidal capability to deter the growth of bacterial slime on the filter face, and demonstrating their capability to remove all forms of pathogens. A major task will be to develop a regenerable filter that uses minimal or no expendables. We will investigate their use as pre-filters for extending the life of reverse osmosis membranes that might be used in AWRS systems. An additional task would determine the feasibility of a microbial trap to maintain sterility of stored water without using iodine disinfectant. We will prove the viability of the filter by designing and testing a full-scale cartridge filter, suitable for NASA and for commercial sale.
