Biotransformation of Soluble Microbial Products (SMPs) in an Anaerobic Baffled Reactor (ABR)

The change in SMP composition of an ABR operating at 24-hour HRT treating synthetic wastewater of medium-strength glucose feed was analysed using SPE-GC-MS. The results showed that alkanes and alkenes generally saw an increase down the compartments of the ABR. The number of esters identified on the...
