Abstract
A laboratory model anaerobic filter was tested in the horizontal configuration for potato processing wastewater treatment, with a view to using it in such a mode in an actual field installation involving earthen construction. The filter media consisted of 25mm to 40mm diameter stones and the hydraulic detention time in the filter during the study was 0.6 day. The reactor was dosed with decanted primary clarifier influent from a potato processing plant, and lime addition was maintained at 500mg/ L of the influent. The anaerobic filter achieved removals of biochemical oxygen demand (BOD), chemical oxygen demand (COD), and suspended solids (SS) of 91%, 91% and 85%, respectively. The average organic loading rate during the study was 1.35kg COD/m3.d. The horizontal anaerobic filter was found to provide organic matter removals comparable to those of vertical-type filters.
