Media for Each Application

Selection of gas filtration media is determined through various investigative procedures and Bioclimatic's experience in similar successful applications. Once gas phase contaminants and concentrations are identified it is possible to select the proper filtration media or combination of media required. Based on airflow rates and gas contaminant concentrations, consumption rates for the gas filtration media are calculated. The desired interval between maintenance cycles then determines the volume of filtration media required for a system.

Protection of process control equipment and computers, corrosion potential and leakage capability of the areas requiring protection are measured in classified environments. Recommendations are made for the media volume, service interval, optimum operating conditions and system placement. Media life is carefully monitored and optimized through a Media Life Analysis program.

Media Life Analysis

Media sampling of operational systems is the “life line” to its successful operation. Typically, representatitive samples are taken at three month intervals to determine rates of media consumption and to estimate the useful remaining life. Moisture levels within media samples are reported. Low moisture levels in BIO-SORB media significantly reduce useful remaining media life and typically indicate unacceptable moisture conditions within the air supply. This analysis enables our customers to optimize system performance and achieve efficient operations. Analytical follow-up service is provided free of charge to all Bioclimatic customers.

Specific Applications*

Bioclimatic's BIO-SORB and BIO-CARB are used to control corrosive gases such as sulfur oxides, hydrogen sulfide and chlorine which attack process control equipment in heavy industry. In light industry, this media is used to eliminate malodorous and nuisance odors which affect people's health and well-being.

Our filtration media is highly effective for indoor air quality applications where airborne contaminants are generated from bioeffluents, operating equipment, furniture, construction materials and outdoor pollution sources.

When Bioclimatic's medias are used within air handling or ventilation equipment, they clean, reduce corrosion, purify and detoxify the air in numerous industries.

Refineries and Petro-chemical Plants
Acid gases and odor bi-products from production of chemicals, polymers, synthetic fibers, paints and fertilizers can be a hazard. Regulate the environment in central control rooms and other occupied spaces.

Steel and Aluminum Manufacturing Plants
Microscopic particles of airborne dust settle on metallic portions of contact surfaces. When dust becomes hygroscopic, water is attracted to the metal surface where dust has accumulated and forms electrolyte films. Remove acid gases and particles which form damaging oxide films.

Power Generation Plants
Process management systems for firing control, fuel flow and automatic turbine start-up are controlled by delicate instrumentation. Feedwater and anti-surge devices are also used in power stations. Protect crucial instrumentation by preventing the corrosive by-products of combustion from entering control rooms.

BIO_SORB 200 Filtration Media is composed of an aluminosilicate substrate impregnated with different chemicals which promotes a chemisorption reaction with a variety of gasses and vapors. The aluminosilicate substrate used in BIO-SORB 200 is a specific type of zeolite that lends itself to the patented technology of permaganate impregnation.

BIO-SORB media may be used alone or blended with other media to achieve the combined properties of both types of media.

How BIO-SORB Works
Aluminosilicates are similar to activated carbon in that they both have very high active surface areas. However, unlike activated carbon, these minerals are able to absorb low molecular weight compounds such as Sulfur Dioxide, Hydrogen Sulfide, Ammonia and Formaldehyde. The BIO-SORB substrate is extremely porous and possesses significant molecular sieve sorption capabilities.

When treated with potassium permaganate, BIO-SORB 200 offers a unique balance of properties.

BIO-SORB media utilizes the adsorptive characteristics of the aluminosilicate to collect the gas contaminant or odor molecule. The adsorptive process brings the gas contaminant molecule into contact with the chemical impregnation. The gas contaminant or odor molecule is then oxidized to a stable salt or odorless non-corrosive by-product.

The aluminosilicate adsorbs and absorbs both moisture and odor. The adsorbed odors collect on the outer surface and interfaces of the granules. The absorbed odors penetrate into the heart of the granules. Moisture dissolves the permaganate, which in turn oxidizes both the adsorbed and absorbed odor molecules.

The permaganate goes through several oxidation stages before its life is completely expended, resulting in the formation of brown manganese dioxide. As the permaganate on the outer surface of a granule is reduced by the intermediate oxidation reaction, the pellet's external color begins to change. The pellet will progress through a brown range of colors from light to dark, from surface to core, as the chemical oxidation capacity is exhausted.


BIO-CARB is a bituminous coal based activated carbon which may be impregnated with a variety of chemicals to enable a neutralization reaction with a variety of gases and vapors. The high quality raw material enables maximum adsorptive capacities with minimum abrasive loss. The media substrate is manufactured in 3.0 mm cylinders with an approximate length of 6.0 mm.

BIO-CARB media may be used alone or blended with other media to achieve combined properties of both types of media.

How BIO-CARB Works
Without impregnation, BIO-CARB media uses physical adsorption without chemical reaction or alternation of the gas phase contaminant in the substrate pore structure to remove gas phase contaminants or odor molecules.

With impregnation, BIO-CARB media uses its adsorptive characteristics of the carbon pore structure to collect the gas contaminant. The adsorptive process brings the gas contaminant molecule into contact with the impregnated chemical. Using adsorption, the vapor pressure of gas pushes the molecule into the pore structure where it sticks to the wall. It uses a reliable process based on chemical oxidation. The gas contaminant or odor molecule is then neutralized to a stable salt or odorless non-corrosive by-product.

Media Features
Crush Strength
High crush strength means superior performance since the dusting threshold is higher than other products and pellets are not susceptible to destruction when subjected to high forces of compression.
Pore Structure
Optimization of media porosity provides more available space for migration of gas phase contaminants, higher sustained efficiency and longer effective life.
Retention Capacity
BIO-SORB and BIO-CARB media do not desorb under surge conditions or sudden changes in temperature or humidity.
Bed Efficiencies
  • Thin bed filtration of less than 0.4 seconds residence time may be used for indoor air quality applications or for light concentrations of gas phase contaminants. One pass efficiencies are approximately 80% over the effective life of the media bed. Bed efficiencies approach 100% when the media bed is fresh as well as during periods when gas concentrations are light.

  • Deep bed filtration with a residence time exceeding 0.4 seconds is frequently used for industrial and municipal applications. System efficiency approaches 99.9%. Increased bed depth promotes longer media life for classified environments, air pollution control or other industrial applications.
