Aerobic desulfurization of biogas by acidic biotrickling filtration in a randomly packed reactor
(2014-09-15)
Article
Restricted access - publisher's policyBiotrickling filters for biogas desulfurization still must prove their stability and robustness in the long run under extreme conditions. Long-term desulfurization of high loads of H2S under acidic pH was studied in a ... -
Application of a novel respirometric methodology to characterize mass transfer and activity of H2S-oxidizing biofilms in biotrickling filter beds
(2015-07-15)
Article
Open AccessThe elimination capacity of gaseous H2S biofiltration can be limited either by mass transfer or bioreaction in the biofilm. Assessment of the biological activity of immobilized cells (biofilm) usually implies morphological ... -
