The permanent storage or disposal of the waste is facilitated by the inorganic and stable structure of the zeolite which can be encapsulated in cement or glass. Cost Effective relative to other methods These zeolites are produced with the high quality assurances. A size specification in the range of 20 by 50 Tyler mesh has been cited as optimal. The decontamination factors achieved by these products often exceed expectations. Large tonnage reserves Finely crushed zeolites are used in sorbent barrier layers.
Exact specifications are dependent upon the engineered permeability of the system.
Existing filtration systems typically contain activated carbon as the adsorbent media. Because most grades of activated carbon contain large internal pores, they tend to trap a wide variety of larger molecules. Zeolites, on the other hand, contain a very small internal pores, in all cases from 3 to 5 angstroms. For this reason zeolite is a highly selective adsorbent of specific gas-phase molecules and elements. Many of the identified indoor air pollutants, including formaldehyde, chloroform, ammonia and carbon monoxide, are in a size range that is most effectively sieved by zeolite.
