Preparation and Characterization of Polyvinyl Alcohol Microsphere Pre-coated Dynamic Membranes
|
Abstract:
To alleviate membrane fouling and reduce the price of membrane module,polyvinyl alcohol microsphere pre-coated dynamic membranes (PVA-MS/PCDMs) were investigated detailedly. It was prepared when the polyvinyl alcohol microsphere of the pre-coated reagent deposited on the surface and entered the pores of porous substrate common filter cloth which was low-cost by means of circulatory filtration. The morphology and structure of PVA-MS/PCDMs were examined using scanning electron microscope (SEM),and approximate...
