About Granulated Activated Carbon
Carbon that is 'activated' undergoes a treatment that opens up millions of tiny pores to enhance the carbon
material's adsorbent properties. The carbon treatment creates a very large internal carbon surface area,
which is key to the filtration of activated carbon. With more surface area, the more the carbon can adsorb.
One pound of activated carbon typically has a surface area of 120 acres. Activated carbon is so
effective that it's used in military gas masks.
A larger Filtercrobe system has 15,000 pounds of
granulated carbon that equals the filtering surface area of 1,800,000 acres
.

Granulated Activated Carbon System With Bio-Filtration (GACBF)
The patented GACBF system is a treatment method used to capture waste off-gases and remove smoke,
particulates and odors by the combination of granulated carbon and naturally-occurring microbes to
biologically degrade the pollutant compounds.

The trapped emission compounds such as VOC's, BTEX, H2S, SO2, HAP's, Odors and Smoke are then
converted by the microbes to innocuous compounds. Granulated activated carbon capture rates vary
depending on the size and molecular weight of the emissions, these generally average between 85% to 95%.
The Filtercrobe is used to control the total air pollutants emitted. Filtercrobe has been tested using the
following EPA References 1 and 2, Volumetric Flow Rate Determination. Method 3, Molecular Weight
Determination; Method 4, Moisture Determination; and Method 25A VOC Concentration Determination.

The Patented Filtercrobe I ®
Filtercrobe I ® vapor phase carbon adsorption system is designed for use at chemical, manufacturing,
casinos, arenas and wastewater treatment facilities. Granulated activated carbon adsorption systems do not
destroy the VOC’s. The Granulated Carbon System traps the emissions, while other competing systems will
require rejuvenation, removal or replacement of the activated carbon by increasing the temperature or by
steam reforming of the highly concentrated vapors then thermally oxidizing the emissions, the Filtercrobe will
require no replacement, heat or steam in the rejuvenation process.

With the patented Filtercrobe design no additional equipment, controls or fuel costs are borne during
the carbon’s rejuvenation phase.
The continual rejuvenation or reactivation of the activated carbon allows
the carbon to
remain within the reaction chamber for up to 20 years without removal.

Typically on granulated carbon systems the emissions are pumped through a series of canisters or columns
containing activated carbon to which the organic contaminants are adsorbed. Periodic replacement,
regeneration or change out of the saturated carbon is required as the method of removing the trapped
Odors, VOC’s, HAPs from the granulated carbon bed. Usually vapor-phase carbon adsorption is not
recommended to remove high contaminant concentrations from the effluent air streams with the economics
favoring pretreatment of the VOC stream, followed by the use of a vapor-phase granulated activated carbon
system as a polishing step.

With the Filtercrobe I ® patented system the activated carbon rejuvenates during operation and
requires no auxiliary heat pump; compressors, nitrogen or chillers for de-adsorption or separate
thermal oxidation equipment for high level Odor, Smoke and VOC destruction.
All the destruction and
removal occurs within the Bio-reactors lower chamber by selected microbes. Higher levels of contaminates
are allowed to be processed by the microbes with a
destruction rate of captured emissions 99+%.

The Filtercrobe I ® offers continual rejuvenation of the granulated activated carbon beds at a rate of
three times per hour, therefore there is no spent activated carbon removal or replacement necessary.

The microbial population is a particular assemblage of natural microorganisms. Initially selected to bio-
remediate any organic compound. The microbes are effective on a wide range to include VOC, H2S, SO2
and Halogenated compounds. The major difference between these microbes and their indigenous cousins is
their density, over 90 billion per gram. The organisms also can double in population every 15 minutes in a
favorably high organic environment. They are
non-toxic and non-pathogenic and have a pre determined
life cycle. This is due to the special characteristics of this collection of microbes
which act as modern filters
for the granulated activated carbon bed
within the Filtercrobe® system.

These microbes will reduce the waste process contaminants within the reactor to near EPA drinking water
standard and may be
discharged to any waste water disposal line without any sludge buildup of any
kind
. Laboratories have found > 1.0 mg/l of VOC's in a sample of water taken from a high VOC operating
system.

When removing emissions and odors, the catalytic carbon bed becomes a extremely large filtration system
for specialized smoke and odor removal at casinos, pumping stations or at wastewater treatment plants. The
difference is the
patented method of cleaning the granulated carbon while in place with no operational
downtime.
The water discharge can be dispensed as normal wastewater.
