Performance of Anaerobic Baffled Reactor/Gravel Bed Filter Towards Domestic Wastewater Treatment

Abstract

The goal of this research is to examine the potential use of anaerobic baffled reactor (ABR) followed by a gravel bed filter (GBF) towards domestic wastewater treatment and to observe the effect of this coupling on the water quality. The efficiency of the system was evaluated through testing the wastewater that is generated from the nearby primary schools (Yaffa and Al- Esteklal). This study illustrated that the use of both the ABR and GBF could be promising in conducting a sustainable onsite wastewater treatment. During the period of the study, samples were taken biweekly and analyzed for BOD, COD, TOC, TP and TN. After 3 months of operation the system stabilized showing high organic pollutants removal efficiencies. According to our recent study the average removal efficiencies of the system is 69% BOD, 77% COD, 60% TOC and 47% P. The microbial analysis indicated a high reduction of total Coliform and Fecal Coliform.
