Filter

Abstract

The invention relates to filtering systems having high adsorbent and filtering properties. A filter comprising an adsorbent powder placed in a nonwoven material, wherein an adsorbent powder of 0.01-10 μm, or 0.01-40 μm, or 0.01-100 μm, or 40-100 μm, or 40-500 μm, or 40-1000 μm, or 100-500 μm, or 100-1000 μm, or 100-2000 μm, or 1000-2000 μm particles size is placed in a nonwoven filtering material with a density of 50-1500 kg/m 3 through impregnating said nonwoven filtering material with aqueous suspension containing the adsorbent, which is prepared in a ratio as one part of water and one part of the adsorbent or in such a ratio that enables the aqueous suspension containing the adsorbent to impregnate said nonwoven filtering material.

1 . A filter comprising an adsorbent powder placed in a nonwoven material, wherein an adsorbent powder of 0.01-10 μm, or 0.01-40 μm, or 0.01-100 μm, or 40-100 μm, or 40-500 μm, or 40-1000 μm, or 100-500 μm, or 100-1000 μm, or 100-2000 μm, or 1000-2000 μm particles size is placed in a nonwoven filtering material with a density of 50-1500 kg/m3 through impregnating said nonwoven filtering material with aqueous suspension containing the adsorbent, which is prepared in a ratio as one part of water and one part of the adsorbent or in such a ratio that enables the aqueous suspension containing the adsorbent to impregnate said nonwoven filtering material.
