The conventional textile wastewater treatment have depended on physicochemical and biological treatment processes such as coagulation/flocculation and sedimentation, and activated sludge processes, which are deteriorated the effluent qualities from the existing system and produced considerably waste sludge. In this study, Biofilter systems and a rapid settling filter(RSF) have been used instead of the pretreatment process of the flocculation and sedimentation process for improvement of effluent qualities. The efficiencies of Biofilters on SS, COD, color, T-N, and T-P are shown as the removal averaged 55.2%, 50.2%, 54.7%, 20.7%, and 29.9%, respectively for the biofilter A packed with ceramic media of 5∼6 mm in effect diameter. As the same efficiencies of the biofilter B packed with ceramic media of 3∼4 mm in effect diameter are shown as 84.2%, 77.7%, 81.8%, 84.2%, 28.4, and 40.8% respectively. As the same efficiencies of the biofilter C packed with ceramic media of 3∼4 mm in effect diameter are shown as 89.6 %, 90.3 %, 88.4 %, 32.3 %, and 40.8% respectively.
