Abstract

The study investigated the effect of varying filter media for nutrient removal in vertical subsurface flow constructed wetlands (VSSFCWs) in the treating piggery wastewater. Ceramic tiles and RHA are proposed as substitute to sand and gravel as reed bed filter media. Each system was assessed based on the following selection criteria: nutrient removal at different retention times (12, 16, 24 hours) and cost-effectiveness. At different retention times, the filter media variation set-up performed better nutrient removal than the other two set-ups. The maximum nutrient removal was achieved by the RHA and ceramic tiles reed bed set-up with 100% nitrate removal and 89.16% orthophosphate removal. The significant difference between the nutrient removal of each set-ups decreases as retention time in the filter bed increases. With these, RHA and ceramic tiles as filter media for VSSFCWs offer a low cost (with minimum cost ratio of 2.4) and effective nitrate and orthophosphate removal for piggery effluent treatment.
