Water recycling using biological filtration system in intensive fish pond system in parameter chemical oxygen demand (COD), phosphate and total suspended solids (TTS)

Abstract

The chemical oxygen demand, total suspended solids and phosphate removal efficiency of sedimentation tank, trickling filter and denitrification tank operated in KUSTEM was studied for wastewater treatment in intensive fish pond system. The filter comprised of three different filter media: the coral sand, coarse gravel and fine gravel. The denitrification tank comprised of bioballs. The aim of this study was to determine the efficient of water recycling that started with or without filtration gave the better performance.
