Denitrification of a nitrate-rich wastewater using various wood-based media materials
Optional Fields
horizontal flow filters denitrification intermittent sand filtration nitrate-nitrogen wood materials SYSTEM BARRIERS REMOVAL
This laboratory study examined the use of various wood materials as a carbon source in horizontal flow filters to denitrify nitrate-nitrogen (NO3-N) from a synthetic wastewater. The filter materials were: sawdust ( Pinus radiata), sawdust and soil, sawdust and sand, and medium-chip woodchippings and sand. Two influent concentrations of NO3-N, 200 mgL(-1) and 60 mgL(-1), loaded at 2.9 to 19.4 mg NO3-N kg(-1) mixture, were used. The horizontal flow filter with a woodchippings/sand mixture and an influent NO3-N concentration of 60 mgL(-1), which operated over a study duration of 166 days, performed best, yielding a 97% reduction in NO3-N at steady-state conditions.
