Crotonaldehyde removal from polluted air using a biofilter packed with a mixed bed

摘要

This study investigated the performance of a biofilter to remove crotonaldehyde from air. Total average of removal efficiency (RE) and elimination capacity (EC) were 88% and 0.73 gm(-3) h(-1), respectively. Nearly 57% of the RE was occurred in the first 20 cm of the biofilter, where the bacterial population (7.42 log(10)CFU g(-1)) and fungi population (5.25 log(10)CFU g(-1)) were significantly more than the other sections. Predominant species of bacteria in the biofilter bed were Pseudomonas,Acinetobacter, and Proteus spp. Finally, it can be inferable that the biofilter can be a suitable method to remove crotonaldehyde from air.
