Study on treatment performance of low cost membrane based septic tank at various fluxesKeywords: membrane based septic tank , domestic wastewater , fouling , septic tank (ST) , Woven Fiber Microfiltration (WFMF) Abstract: The objective of this study was to evaluate the performance and fouling behavior of membrane based septic tank (MBST).Woven Fiber Microfiltration (WFMF) introduced in the chamber of a septic tank as a submerged membrane for domestic wastewater treatment. Concentrations of black water stored in the third chamber were 125 ± 15 mg/L COD, 124 ± 28 mg/L SS and 59 ± 9 mg/L TKN. Results showed that COD removal was 54-78 % of which effluent achieved less than 50 mg/L. In addition, the withdrawal was mostly non-performed suspended solids. TMP level increased gradually, indicated low membrane fouling rate (dTMP/dt) of 0.4-1.0 kPa/day at flux as low as 2.5 LMH. While at the flux greater than 3.4 LMH the fouling rate increased rapidly with the fouling rate of 13 kPa/day. doi: 10.12777/ijwr.3.1.1-4 [ How to cite this article: Thanh, B. X., & Dan, N. P.
