An oil palm fiber module has been developed to modify a down-flow hanging sponge (DHS) reactor module. The objective of the proposed system is to improve two existing DHS variants of post-treatment unit for UASB treating domestic wastewater, i.e. cube-type and curtain-type sponge as domestic wastewater treatment system for developing countries. This paper describes the potential of oil palm fiber-based DHS (PF-DHS) configuration for sewage treatment. Feasibility of the PF-DHS reactor was evaluated by conducting a six-month continuous operation using actual sewage as feed. The system has been verified to have an excellent organic removal performance achieving 67% of unfiltered COD removal, and nearly perfect SS removal at the HRT of 2 h. It was observed that the organic removal rate was approximately 2.64 kg COD/m3 per day. The result recommended that the proposed PF-DHS reactor would be a promising system to alter sponge-based DHS for domestic wastewater treatment system in developing countries.
