Consisting of immobilized activated carbon and cellulose fibers, Unifiltech's Nanopham C depth filter media provides superior adsorption characteristics over traditional stirred tank or packed bed carbon applications. Designed for use in a single-pass process, the large surface area of carbon to the process stream enables highly efficient color or  odor removal. Unlike other depth filter media, designed for mechanical particle removal, Nanopham C depth filter media are designed for adsorption of colors, odors or other soluble contaminants.

Activated carbon is highly porous over a broad range of pore sizes, from cracks and crevices to molecular dimensions. It is this porosity that provides activated carbon's unique adsorptive properties. Generally, activated carbon contains surface areas in the range of 500-2000m²/gm. “Activation”refers to the development of the adsorption properties of carbon. Adsorption occurs when the organic molecules bond to the internal pores of the activated carbon. This happens in pores slightly larger than the molecules being adsorbed, which makes it extremely important to match the molecule being adsorbed to the pore size of the activated carbon.

Careful blending of filter aids and cellulose fibers with activated carbon yields sub-micronic filtration and adsorptive treatments concurrently. Unifiltech manufactures carbon-impregnated media in a range of removal ratings and configurations. This provides standardization of carbon treatment in addition to simplicity and ease of handling and   operation.
