Effect of Trans-Membrane Pressure on Reversible and Irreversible Fouling Formation of Ceramic Membrane

Year: 2012

Type: article

Abstract: This study was carried out to investigate how reversible and irreversible fouling were distributed in the filtration using ceramic membrane of 300 kDa pore size for secondary effluent of wastewater.It was performed by calculating fouling as numerical method for diverse TMPs and measured F-EEM and SEC for raw water, treated water and backwashed water.Water quality was also checked to know whether treated water quality was stable or not.The results showed that reversible fouling formation was increased when lower TMP was applied and it is caused by protein like organic matters having higher molecular weights.The secondary wastewater effluent had diverse molecular weight materials, especially contaminants lower than 0.5 kDa and bigger than 12 kDa.Decreasing TMP induced contaminants above 12 kDa and below 1 kDa to become reversible fouling.
