Zeta Plus Filter Medium: The efficient way to decolorize your process liquids
Zeta Plus filter medium incorporates the latest activated carbon technology to decolorize and remove contaminants from your process streams. Zeta Plus filter media can be used in any application where bulk activated carbon is used.

Zeta Plus Principle
The activated carbon is made into Zeta Plus filter media with the addition of cellulose fibers and a positively charged resin. This eliminates the use of bulk carbon that causes dust-related issues especially for operators.

3M Purification incorporates five standard types of activated carbon to cover a broad range of applications. These have been specifically selected for their properties to meet industry requirements. Zeta Plus filter media are also available in different porosities so that solutions with different viscosities can be processed.

Flow Rate Influence
Adsorption of molecules by activated carbon relies on Vander Waals' forces. As those interactions are of short range, contact time between the solution and the filter media is critical. Graph 1 in the datasheet shows the influence of the flux on the adsorption capacity of the filter media. It shows that when the flux increases the adsorption capacity of Zeta Plus filter media decreases.
