Description A novel immobilised bioreactor has been developed especially for the treatment of pollutants characterized by high volatility alongwith
high water solubility and low microbial yields. The new bioreactor referred to as the rotating rope bioreactor (RRB) provides higher
interfacial area (per unit reactor liquid volume) along with high oxygen mass transfer rate, greater microbial culture stability; and consequently
higher substrate loadings and removal rates in comparison to other conventional rectors for the treatment of volatile compounds.
Pyridine was used as a model compound to demonstrate the enhanced performance with RRB, when compared to that
reported with other conventional bioreactors. The experimental results indicate that the novel RRB system is able to degrade pyridine
with removal efficiency of more than 85% at higher pyridine concentration (up to 1000 mg/l) and loading [up to 400 mg/m2/h (66.86 g/
m3/h)], with a shorter hydraulic retention time (9–18 h). The reactor has been in operation for the past 15 months and no loss of activity
has been observed.
