Sažetak
Granular activated carbon (GAC) was used as a support for biomass growth in biological filtration process treating coking wastewater with the aim of reducing ammonia concentration. Advantages of such media are high specific surface area, porous microstructure and low production cost [1]. Wastewater after treatment in a two- stage biological plant, using activated sludge technology is subjected to biological filtration. The wastewater enters a conical reactor, volume 15 L, which is aerated via a perforated tube and a blower, from where it is recirculated to the activated carbon column seeded with activated sludge from municipal wastewater treatment plant. Kinetic experiments were performed for 24 hours and samples were collected through that period. Ammonia concentration was reduced from 56.39 mg/L and 66.31 mg/L to 14.62 mg/L and 19.95 mg/L, respectively.
