Active carbon filters: Clean biogas improves uptime and engine life
Carbon filtering is a method of filtering that uses a piece of activated carbon to remove contaminants and impurities, utilising chemical adsorption.
Each piece of carbon is designed to provide a large section of surface area, in order to allow contaminants the most possible exposure to the filter media. One pound (450 g) of activated carbon contains a surface area of approximately 100 acres (40 Hectares).
This carbon is generally activated with a positive charge and is designed to attract negatively charged water contaminants. Carbon filtering is commonly used for water purification, but is also used in air purifiers.
Carbon filters are most effective at removing H2S, siloxanes and volatile organic compounds (VOCs) from biogas derived from the anaerobic digestion process.
Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 micrometres. The particle size will be used as part of the filter description. The efficacy of a carbon filter is also based upon the flow rate regulation. When the water is allowed to flow through the filter at a slower rate, the contaminants are exposed to the filter media for a longer amount of time.
