Question

Biodegradation of gaseous toluene with mixed microbial consortium in a biofilter: steady state and transient operation

Answer 1

ANSWER AND Explanation:

Petroleum oil refineries are massive emitters of risky volatile organic compounds (VOCs).  

Among the VOCs, toluene is taken into account as a significant pollutant. In the present  

study, a compost biofilter is used to treat the toluene vapor. However, an elimination capacity  

and removal efficiency of the biofilter was investigated for a wide range of toluene  

concentrations (0.29–3.8 gm− 3) and operated for 54 days effectively. Elimination capacity of  

93 gm− 3 h− 1 was recorded as maximum value at a toluene inlet concentration of 114 gm …
