A pilot project research has been conducted to eliminate odor pollution from the feed mill industry. The feed industry in Indonesia has grown, especially in poultry feed production produced in modern feed mills equipped with pelleting technology. This industry is also having an environmental impact in the form of air pollution of its production activities. The laboratory analysis showed that ammonia has emitted, and it was the dominant parameter as the cause of odor in air pollution. This research aims to remove ammonia emissions using dry filtration technology with activated carbon as the filter media in the upright reactor. The reactor is designed from stainless steel material, consisting of 3 trays. The distance between trays is 300 mm, the dimensions of the tray are L.2430 mm, W.1815 mm, H.600 mm, the tray hole diameter is 3 mm. The average gas flow rate is 200-300 Nm 3 /min. Activated carbon used granules, size 6-8 mm, 200 mm thick in the tray. The results showed that the efficiency of ammonia removal was 81.96%-94.40% and had met the quality standards. This technology is feasible to control ammonia as an odor pollutant in the feed mill industry.
