SAAFBlend™ WS media is produced from an equal volumetric mix of SAAFCarb™, SAAFCarb™ MA, and SAAFOxidant™ media. Manufactured of spherical and porous pellets. SAAFOxidant™ engineered media is composed of a combination of activated alumina and other binders. Potassium permanganate is applied uniformly during pellet formation and is distributed throughout the pellet volume. This process provides the maximum amount of impregnant for chemical reaction and optimal performance. SAAFCarb™ media is manufactured of pelletized activated carbon media that is composed of high-quality virgin substrates, in order to provide optimum adsorption for various gaseous contaminants. SAAFCarb™ MA media is composed of pelletized activated carbon media suitably impregnated for the removal of acid gases.
SAAFCarb™ media removes toxic and impure gases primarily by adsorption. In this process, the gases remain on the surface of the pellet.
The SAAFOxidant™ and SAAFCarb™ MA media chemisorption process removes the contaminant gases by adsorption, absorption, and chemical reaction. In this process, the gas is trapped within the pellet, where oxidation changes the gases into harmless solids and thereby mitigates the possibility of desorption.
SAAFBlend™ WS media contains an equal volumetric mix of SAAFOxidant™, SAAFCarb™, and SAAFCarb™ MA media. Each media undergoes respective quality control tests. All these tests are to make sure that the physical as well as chemical properties can play its own role to achieve the performance designed for this media.
The quality control tests included:
- Apparent Density
- Ball-pan Hardness
- Crush Strength
- CTC Activity
- H2S Gas Capacity
- Moisture Content
- Pellet Diameter
