Rapid Start-Up of Biofilter for Removal of Iron and Manganese from Groundwater
“aged” biofilter media was adopted as the inoculum to accelerate the maturation of biofilter for iron and manganese removal in the start-up of filter column. morphology of “aged” biofilter media and new quartz sand was observed with SEM. The results indicate that the “aged” biofilter media coated by a large quantity of bacteria which reduces the start-up time to 30 daysand affords strong Mn-removal efficiency at the beginning of the process. This method probably can be used for the start-up of new filters when there are well-established biofilters around.
