Climate - Gas Phase Media
Certain environments demand the removal of gaseous pollutants and toxins from the air that can best be achieved with gas phase filtration.
Gas phase filters, also known as chemical media filters, ensure continuous removal of odorous, toxic, or corrosive contaminants in industrial, institutional, and commercial environments. Bioclimatic's gas phase filtration has a long history of proven reliability and predictability that predictably and reliably delivering these benefits:
- Proven safety performance
- Best one-pass contaminant removal
- Flexible product options to properly meet the specific need
- Protection of equipment for reduced Total Cost of Ownership
- Occupant satisfaction and employee retention with elimination of bad odors
Using adsorption, absorption, and chemisorption Bioclimatic's broad range of media options are used to control corrosive gases such as sulfur oxides, hydrogen sulfide, and chlorine which attack process control equipment in heavy industry. They are used to eliminate odors which can affect people's health and comfort. And our filter media is highly effective for indoor air quality applications where airborne contaminants are generated from bio-effluents, equipment, outdoor pollution sources, or off-gassing from furniture and construction materials.
Two general categories of media are available to meet most challenges. BIO-SORB filter media is composed of either an alumina or aluminosilicate substrate impregnated with different chemicals which promotes a chemisorption reaction with a variety of gasses and vapors. For example, the alumina substrate used in our BIO-SORB 100 lends itself to the time proven technology of potassium permanganate impregnation. BIO-SORB media may be used alone or blended with other media products to achieve the combined properties of other types of media. BIO-CARB media is a family of activated carbon products manufactured from wood, bituminous coal, or coconut shell raw materials. The different raw materials offer different performance against various gasses allowing the best choice for effectiveness and cost.
Bioclimatic chemical media features:
- Dust Attrition - Low dust attrition means minimal loss of media, less settlement and air bypass, reduced loading of after-filters, and improved performance.
- Pore Structure - Optimizing media porosity or pore structure provides more space for migration of contaminants, higher sustained efficiency, an affinity for specific families of chemicals, and longer effective media life.
- Retention Capacity - Bioclimatic's media do not desorb under surge conditions or sudden changes in temperature and humidity. Its high quality provides the highest possible retentive capacity, an important performance attribute.
- Bed Efficiencies -
- Thin bed filtration with short residence time may be used for indoor air quality applications or where there are relatively light concentrations of gas contaminants. Typical single pass efficiencies average 80% to 90% over the life of the media.
- Deep bed filtration with longer residence time is commonly used for corrosion protection, odor control under demanding conditions such as waste water treatment plants, and toxic gas control. System efficiencies can exceed 99%. Larger bed depth also allows extended operation between servicing.
- Airport terminal air intake near jet engine exhaust
- Waste water or sewage treatment for odor mitigation
- Hospital air purification
- Corrosive, acidic environment
- Chronic air pollution challenges to archival storage areas
- Heavy industry, chemical plants, or food processing
- Casinos and hospitality
- Building security and safe havens
Monitoring media usage is essential to successful operation of gas phase media systems. Bioclimatic offers analysis of the media to determine the replacement cycle necessary for peak performance. Representative samples of media are taken at periodic intervals to determine rates of media consumption and to estimate remaining useful life. Media samples are laboratory analyzed to provide an accurate picture of the field conditions and provide information to improve the system performance.
