FiltaMin - Zeolite absorbent rock filter media

Bioaction supply a range of zeolite rock media materials:

• Natural Zeolite
• Impregnated Zeolite

Natural zeolites are volcanic minerals, which act as ion-exchange agents and are known to have a high negative charge and high absorptive properties. Zeolites are also produced industrially on a large scale. As of October 2012, 206 unique zeolite frameworks have been identified, and over 40 naturally occurring zeolite frameworks are known.

Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that upon rapidly heating the material stilbite, it produced large amounts of steam from water that had been adsorbed by the material. Based on this, he called the material zeolite, from the Greek ζ?ω (zéo), meaning "to boil" and λ?θος (líthos), meaning "stone".

Zeolites have a porous structure that can accommodate a wide variety of cations, such as Na+, K+, Ca2+, Mg2+ and others. These positive ions are rather loosely held and can readily be exchanged for others in a contact solution. These reactions and the porous nature of the rock are what make zeolites such a good filtration media within biological filter systems. Some of the more common mineral zeolites are analcime, chabazite, clinoptilolite, heulandite, natrolite, phillipsite, and stilbite.

Natural zeolites form where volcanic rocks and ash layers react with alkaline groundwater. Zeolites also crystallize in post-depositional environments over periods ranging from thousands to millions of years in shallow marine basins. Naturally occurring zeolites are rarely pure and are contaminated to varying degrees by other minerals, metals, quartz, or other zeolites. For this reason, naturally occurring zeolites are excluded from many important commercial applications where uniformity and purity are essential.

Zeolites are also widely used as catalysts and sorbents. Their well-defined pore structure and adjustable acidity make them highly active in a large variety of reactions. Zeolites have the potential of providing precise and specific separation of gases including the removal of H2O, CO2 and SO2 from low-grade natural gas streams. Other separations include noble gases, N2, O2, Freon and Formaldehyde.

Impregnated zeolite rock media variations

The porous nature of zeolite allows it to be modified and adapted for specific filtration applications. The material can be impregnated with compounds and chemicals specifically suited to capturing many different types of gas or emission and thus act as a filter media. To enhance the performance of a given filter, based on the target gases for removal Bioaction use zeolite to filter specific gases from air phase filtration systems.
