Abstract

The Submerged Membrane Adsorption Hybrid system (SMAHS) is an attractive solution in treating wastewater; however it faces membrane fouling although to a less extent. In this study, different adsorbents and resins were investigated in order to find a substitute to the Powdered Activated Carbon (PAC); The effect of new backflush was also studied in further reducing the membrane fouling. The SMAHS led to 72 to 86% dissolved organic carbon (DOC) removal. A detailed study on the transmembrane pressure development led to a conclusion that there is a critical flux and this value is around 16l/h.m2 for the wastewater studied.
