A METHOD FOR REMOVAL OF NANO-SIZED PATHOGENS OF A SIZE FROM 20NM TO 500NM FROM WATER

摘要

The present invention relates to a method of removing nano-sized pathogens of a size from 20nm to 500nm from water, the method comprising contacting the water with a filter comprising activated carbon particles, wherein said filter has a Virus Removal Index (VRI) of at least 99.99% , characterized in that said activated carbon particles comprise a mixture of activated carbon particles of different size and/or shape, wherein said mixture of activated carbon particles has inter-particle spacings that result in bulk density of from 0.61 to 0.8 g/cm3 and wherein said particles of said mixture of activated carbon particles have particle sizes 0.1 µm to 5000 µm.
