Biofiltration was found to be a possible process for humic acid removal once filters had been acclimated to a synthetic feedwater for 12-16 months. The biofilters were exposed to a synthetic feedwater with influent TOC concentrations ranging from 1.6-4.5 mg L -1 and a composition of 65% humic acid, 15% formate, 10% acetate and 10% formaldehyde on a carbon mass basis. TOC removals improved from 19 ± 13% (n = 15) to 49 ± 10% (n = 20) in one biofilter and from -11 ± 25% (15) to 51 ± 7% (n = 20) in… CONTINUE READING
