The removal of hydrogen sulfide (H 2 S) was investigated in a lab scale biofilter packed with biomedia, encapsulated by sodium alginate and polyvinyl alcohol (PVA). The main H 2 S oxidation products were SO42-, SO32-, S 2− and S 0 . The immobilized cell biofilter required no separate acclimatization period and showed high removal efficiencies (RE) within the first few...
The performance of a lab scale biofilter packed with biomedia, encapsulated by sodium alginate and polyvinyl alcohol was used for treating ammonia (NH 3 ) gas at different loading rates. The metabolic end products during NH 3 oxidation were NH4+, NO3- and NO2-. It is noteworthy to mention that the immobilized cell biofilter required no separate acclimatization period and showed high...
