Overview Technical Specification Application

Bry-Air has a wide range of proprietary chemical media for Gas Phase Filtration to eliminate corrosive, odorous and toxic gases from Industrial and Commercial environments.

BRYSORB™ series offers a range of combinations of Activated Carbon and Activated Alumina impregnated with various impregnates which neutralises various gaseous contaminants such as H₂S, SO₂, Cl₂, NH₃ and other VOCs.

BRYSORB™ 508

BRYSORB™ 508 granular media is an Activated Alumina impregnated with Potassium Permanganate (KMnO₄).

BRYSORB™ 508 chemical media is used to remove a variety of contaminant gases from air in hostile industrial environments such as Hydrogen Sulphide (H₂S), Sulphur Dioxide (SO₂), Sulphur Trioxide (SO₃), Nitric Acid (HNO₃), Formaldehyde (CH₂O), Ethylene (C₂H) and Aldehydes (-CHO).

BRYSORB™ 508 Blend

BRYSORB™ 508 blend granular media is an Activated Alumina impregnated with Potassium Permanganate (KMnO4) and other proprietary chemicals.

A perfect blend of BRYSORB™ 508 and BRYSORB™ 520 for optimum removal of harmful and odourous gases such as Ozone(O₃), Hydrogen Fluoride (HF) and various other VOCs.

BRYSORB™ 515

BRYSORB™ 515 granular media is an Activated Alumina and Activated Carbon impregnated with Potassium Hydroxide (KOH) for the effective removal of Chlorine (Cl₂) and Sulphides (SOx).

BRYSORB™ 515 chemical media is basically lowering or raising the pH to a neutral condition with a change of state from a gas to a solid, stable salt. This is good to remove gases such as Hydrogen Sulphide (H₂S), Sulphur Dioxide (SO₂) and Chlorine (Cl₂).

BRYSORB™ 520

BRYSORB™ 520 granular media is pure Activated Carbon. This is neutral in nature.

BRYSORB™ 520 is the media in which one substance gets attracted and adheres to the surface of another. Atoms and molecules are held together in a solid by physical forces, as strong as a valence (chemical) bond and as weak as Van der Waals (physical) attractive forces. This removes toxic gases such as Chlorine (Cl₂), Nitrogen Oxide (NO), Carbon Disulphide (CS₂), Toluene (C₇H₈), Isopropyl Alcohol (C₃H₈O) and trichloroethene (C₂HCl₃).

BRYSORB™ 525

BRYSORB™ 525 granular media consist of cylindrical, porous pellets formed by the combination of Activated Carbon impregnated with Phosphoric Acid (H₃PO₄) for effective removal of Ammonia (NH₃).

Bry-Air offers the latest technology in gaseous adsorption – Gas Phase Activated Carbon process which greatly increases the adsorption capacities of Activated Carbon. The Phosphoric Acid (H₃PO₄) impregnation is done in such a way as to ensure uniform distribution across the entire volume of the pellet so that the target gas will react with chemical media.

Testing Facility at Site

The chemical media used in the chemical filter is consumable and cannot be regenerated. Therefore it has to be replaced whenever consumed. Determining the time of replacement is important so that media is not replaced when its life is left or we keep on using the system once the chemicals are consumed also.

Bry-Air has an in-house lab to ensure that the media is checked at regular intervals and changed at appropriate times. Bry-Air provides you with the facility to check the “life” of chemical media free of cost.

Frequently Asked Questions

How do I determine which chemical media is suitable for my application?

Chemical media selection depends on the target contaminant, concentration, airflow, temperature, relative humidity, operating hours and required removal efficiency. A proper gas phase filtration media selection should therefore be based on the actual operating conditions and contaminant profile.

What information is required to select the correct gas-phase filtration media?

Important parameters include contaminant type, contaminant concentration, airflow/CFM, temperature, relative humidity, operating hours, filter dimensions and required media life. This information helps determine the appropriate chemical filter media and filter configuration.

How does contaminant concentration affect chemical media consumption?

Higher contaminant concentrations generally increase the rate at which the active capacity of chemical filtration media is consumed. Therefore, contaminant concentration is an important parameter when estimating gas-phase filter media life and replacement intervals.

How does airflow affect the performance and life of gas-phase filtration media?

Airflow determines the quantity of contaminated air passing through the media and influences contact time between the gas and the adsorbent. Correct airflow and face velocity are therefore important for effective gas-phase filtration and media-life estimation.

How does relative humidity influence activated carbon and impregnated media performance?

Humidity can influence adsorption and chemical reaction mechanisms in activated carbon and impregnated chemical media. Excessive moisture may compete for adsorption sites or affect the performance of certain media formulations.

How can I estimate the remaining life of chemical filter media?

Remaining media life can be assessed using operating conditions, contaminant loading, historical replacement data and, where appropriate, laboratory testing. A chemical media life assessment can provide a more reliable basis for replacement planning.

What are the signs that chemical filter media has reached the end of its useful life?

Possible indicators include increased contaminant concentration downstream, breakthrough of the target gas, deterioration in corrosion-control performance or laboratory evidence of reduced media capacity. These indicators should be evaluated before chemical filter media replacement.

Can spent chemical media increase the risk of downstream corrosion?

If reactive gases pass through exhausted media, the downstream environment may again be exposed to corrosive contaminants. Timely gas-phase filter media replacement can therefore be an important part of an electronic and equipment corrosion-control strategy.
