Microspheroidization treatment of macroporous TiO2 to enhance its recycling and prevent membrane fouling of photocatalysis-membrane system

Formation of PP-TiO2 cake layer on the membrane surface induces membrane fouling, low photoactivity and permeation flux of membrane, while the suspension of PP-TiO2/CA microspheres in dye solution can prevent membrane fouling, increase titania photoactivity without decreasing the membrane permeation flux.
