Gas samples were collected from ports located at the biofilter
inlet (port A) and outlet (port D) using a 1-ml Hamilton gas tight
syringe. After achieving steady-state condition in the operation
of the system, sampling from ports B and C was done.
All samplings were carried out at the end of loading time due
to some researchers demonstrated that biofilter performance
gradually increased during the course of each loading period
(Moe and Qi, 2004). Toluene concentrations were then measured
using a gas chromatograph (Younglin ACME 6000 series)
equipped with a flame ionization detector (FID). Helium was
used as the carrier gas and the temperatures of oven, injector
and detector were 120, 150 and 250 ◦C, respectively.
To study the possibility of clogging during the experiments,
the bed pressure drop was measured by a manometer with
1mmH2O precision.
