Activated Carbon Filter systems by Likusta

Waste gas treatment and odour control systems

Activated Carbon Filters are designed and used for the removal of vapors and odours which still may be present within the air or gas flow.

The main odorous gases commonly found in sewage / biogas are:
• Hydrogen sulphide
• Indole and skatole
• Methyl mercaptan
• Methylamine
• Ammonia

The activated carbon filter adsorbs vapors and bind them to the surface of the activated carbon. The zero odour level is reached by contacting the air through a bed of activated carbon in an adsorber. The carbon bed is sufficiently deep to assure complete odour removal at the nominal working point, but also at unexpected or seasonal peak concentrations. The contact time between the air and the activated carbon should be between 2-4 seconds.

We provide catalytical carbon for special application of H2S-removal. The H2S will be catalytical converted into elemental sulphur and can be washed back by water.

Despite the thick bed depth, the differential pressure remains very reasonable. Indeed, the pelletised carbon type water regenerable 4 mm size, is assuring 25 % less pressure drop than a conventional gas phase carbon. The reduced pressure drop results also in 25 % energy cost savings.

The air leaves the filter free of objectionable odour. Potable water only is used to wash the saturated carbon. Special catalytical carbon designed to remove at least 99 % of the odorous gases from air within a temperature range of 0 – 60°C and a humidity range of 40-90%. Easy replacement of used carbon: No need of chemicals, storage tanks, pumps, special safety instructions, training for handling chemicals, safety showers, special chemical resistant clothing, safety glasses etc.
