Product Composition:
Zeolites were formed from ancient volcanic ash flows settling in seas
and lakes. This unique group of naturally-occurring minerals is often
referred to as ‘molecular sieves’. Zeolite is the world’s only mineral
with a naturally-occurring negative charge. Zeolites simply lock & hold
many positive ions, absorbing a multitude of environmental contaminants
such as sodium, potassium; barium and calcium, and positively charged
groups such as water and ammonia.
Zeolite and the Environment
Nearly every application of zeolite has been driven by environmental
concerns, or plays a significant role in reducing toxic waste and energy
consumption. It is the highly porous and consistent matrix of zeolite
that provides the absorption qualities. One important factor to
determine a natural zeolites’ quality is the percentage of a primary
mineral within the zeolite matrix - called ‘clinoptilolite’.
Clinoptilolite
Clinoptilolite, one of the most useful naturally occurring zeolites, is
applied as a chemical sieve, food additive, as well as gas and odor
absorber. Clinoptilolite can easily absorb ammonia and other toxic gases
from air and water and thus can be used in filters, both for health
reasons and odor removal.
BRZ Zeolite
The zeolite source located in Idaho is the highest grade of
naturally-occurring zeolite due to its clinoptilolite content of 95%. In
comparison, many other of the world’s zeolite mines are in the 30% to
70% range. BRZ zeolite is approved by NASA for its ability to hold soil
nutrients for long-term flights in space and it has NSF approval for use
as an alternative to traditional water treatment filters.

GSA Chabazite
Chabazite is the most important member of the 48 minerals in the
zeolite group. It is the microcrystallinity of the chabazite that
produces a large surface area and pore volume which promotes
accelerated ion exchange and sorption rates as well as high
permeability. The only known deposit of its size and purity in the
world, is located at Bowie, Arizona, U.S.A. As evidenced below, the
Bowie, Arizona Chabazite is often the zeolite of choice.
United States Patent # 6,042,731, titled "Method of removing arsenic
species from an aqueous medium using modified zeolite minerals" was
issued on March 28, 2000. The zeolite mineral that is the base
element in this patent is known as Chabazite. The Chabazite used in
this technology is from a deposit located at Bowie, AZ.
Union Carbide Corporation, Tarrytown, NY) marketed an AW-500 product
(natural chabazite-rich tuff from Bowie, AZ) for removing HCl from
reformed H2 streams H2O from Cl2, and CO2 from stack gas emissions.
NRG Corporation (Los Angeles, CA;) used a pressure-swing adsorption
process with Bowie chabazite to remove polar H2O, H2S, and CO2 from
low-BTU natural gas and developed a zeolite-adsorption process for
purifying methane produced by decaying garbage in a Los Angeles
landfill.
Why do we include two zeolites, Clinoptilolite and Chabazite?
Because each absorbs different chemicals at different
rates. Excerpted from… Sabeha Kesraoui Ouki, Department of Civil
Engineering, University of Surrey, Surrey U.K. “Two natural zeolites,
clinoptilolite and chabazite, have been evaluated with respect to
their selectivity and removal performance for the treatment of
effluents… Clinoptilolite and Chabazite exhibited different
selectivity profiles…
Simply put, using both minerals yields far better results than
either one. And using only the best zeolites available makes a huge
difference. But still more can be done to keep food fresher,
longer!
Potassium Permanganate
Ethylene is a natural plant hormone produced by metabolism in most
fruit and vegetables. It initiates and accelerates the spoiling of
fruit vegetables. To prevent degradation of produce due to exposure
to ethylene gas, ethylene gas absorbers have been developed. One of
the simplest ways to remove ethylene gas is to absorb it with
potassium permanganate.
Montmorillonite
Montmorillonite absorbs water due the interlayer molecular spaces.
Montmorillonite is so absorbent that it is used as a non-explosive agent
for splitting rock in natural stone quarries or for the demolition of
concrete structures where the use of explosive charges is unacceptable.
And Montmorillonite is safe. Montmorillonite has been used in cosmetics
and has reputed therapeutic effects. Over 200 cultures have used it for
medicinal purposes including the Ancient Egyptians, and natives of
Mexico, South America and North America. Montmorillonite is also used in
animal feeds as an anti-caking agent.
