What are Alumina Nanofibers?

Alumina nanofibers are very small fibers made from aluminum metal or aluminum containing materials. The fibers range in size from 1-100 (nm) in diameter and can be up to several micrometers in length. To give perspective, a sheet of paper is about 100,000 nanometers thick. Alumina nanofibers consist of either aluminum oxide (Al2O3) or aluminum hydroxide, such as aluminum oxide hydroxide (AlOOH), commonly referred to as boehmite, or aluminum trihyroxide [Al(OH)3], commonly referred to as gibbsite, bayerite or nordstrandite.

How Alumina Nanofibers are used for Treating Drinking Water?

Alumina nanofibers have been incorporated into cartridge filters to increase their ability to remove contaminants. The nanofibers have two particular attributes that make them attractive for use in drinking water filters – the proven capability of alumina to adsorb various contaminants in conjunction with the extremely high surface areas of the nanofibers allow for potential adsorption of significant amounts of contaminants. This could extend the life of a filter. The electrostatic attraction allows for the potential adsorption (and thus removal) of viruses which are on the submicron and nanoscale. This would improve a filter‟s microbial pathogen removal capabilities. Research has shown the potential for Al2O3 alumina materials and Al2O3 alumina nanofibers to remove or reduce virus concentrations in water.

2001 Argonide receives a SBIR award from NASA for biological filter for space cabin water.

NANO FIBER BIOLOGICAL FILTER

Alumina (AlOOH) nanofibers (NanoCeram™) only 2 nm in diameter were developed in Russia under a CRADA of Argonide with the Department of Energy. Argonide immobilized the fibers into a filter and subsequently was awarded an SBIR contract by NASA to develop a filter for space cabins. The filters, which received a “Best 100 New Product” award by R and D magazine, are being commercialized in January 2003 in the form of laboratory size filters for biotech applications. The filters are highly electropositive as a result of the high surface area, covered by hydroxide groups and attract and retain pathogens and virus that are principally electronegative.

2002 NanoCeram® technology initiated

About NanoCeram Technology

Argonide’s NanoCeram® patented filter media features a thermally bonded blend of microglass fibers & cellulose infused with nanoalumina fibers in a non-woven matrix that creates an electropositively charged depth filter media. When assembled into a pleated cartridge, all NanoCeram® filter offering provide a unique combination of efficiency, capacity, flow rate & low pressure drop at levels unmatched in today’s filtration marketplace. In addition, all NanoCeram® filter cartridges are assembled using only FDA-compliant materials.

How Does It Work?

SBIR Phase II award from NASA

US space agency NASA awards a phase II Small Business Innovation Research (SBIR) grant to Argonide, US. The company will use the funding to develop a “nano ceramic sterilization filter” for recycling water in space cabins.

Argonide wins R&D magaine “Best 100 New Products” for NanoCeram®

SBIR Phase I award from EPA for Arsenic Filter

Argonide Corporation proposes to develop and design a prototype cartridge filter for residential use that would meet the 10 µg/L standard. Should filter regeneration prove to be economically feasible, more definitive absorption/regeneration cycling for the purpose of POE applications would be performed during Phase II.
