Abstract
In the present work composite UF membrane for refinery effluent treatment was prepared using sulfonated Poly (1, 4-phenylene ether ether sulfone) (SPPEES) and TiO2 nano-sized particles by phase inversion method. The sulfonation of PPEES was done to improve its chemical and thermal stability. The PVP was added in the blending solution as a pore forming agent. The sulfonation of PPEES also improves the hydrophilicity of the membrane. The addition of nanosized TiO2 particles also increases the hydrophilicity of the prepared membrane and improves its antifouling property. The surface morphology was studied using SEM. The mechanical strength and water contact angle of the membrane was studied before application of membrane for refinery effluent treatment. The refinery effluent was collected from IOCL refinery Panipat, and was used to test treatment efficiency of the prepared membrane. The result of water flux and permeate flux was shown at constant velocity and transmembrane pressure of 3m/s and 0.3MPa respectively. The experimental results obtained in the present work shows the permeate flux decline of 35% after 75 minutes. The permeate water obtain was having almost 95% removal of TDS and 50% removal of organic contaminants. The possible use of SPPEES-TiO2 membrane for refinery effluent treatment was discussed.
The study reports the surface morphology of the SPPEES material and effect of addition of TiO2 nano sized particle in the formation of membrane. TiO2 nano sized particle was used as an antifouling material and PVP for pore forming agent. The surface morphological study was done using SEM. The permeate flux against time were recorded.
