Biofiltration of trihalomethanes stripped from chlorinated drinking water

This study examined the removal of chloroform under two environmental conditions (anaerobic and aerobic), and in the presence of ethanol as co-metabolite. Investigations of the biological community structure within the BTFs were also conducted. The use of aerobic fungi BTF under acidic condition successfully enhanced the biodegradation process of chloroform. The BTF provided more stable performance by having smaller standard deviation in the removal efficiency as compared to the anaerobic BTF. Hence, acidic aerobic BTF had achieved significant improvement in the removal of chloroform.
