Title
Polymeric membranes: Tailor-made casting and their applications
Abstract: Membrane is a phase that allows selective transport of a species through them resulting to physical separation of a species. Polymers are one of the key components to prepare these membranes. Polymeric membranes have numerous applications starting from water treatment to various industrial applications ranging from pharmaceuticals to food processing and treatment of various industrial wastewater. This talk demonstrates how casting conditions would result to membranes of various characteristics. Also a novel and cost effective method would be discussed to spin hollow fiber polymeric membranes of various grades starting from microfiltration to dialysis. Various applications of polymeric membranes would be elaborated.The applications can broadly categorized in (1) treatment of industrial wastewater; (2) extraction of phytochemicals from plants; (3) Processing of fruit juice; (4) electric field assisted filtration; (5) micellar enhanced ultrafiltration. Also various plant scale and laboratory scale systems for membrane separation those have been developed in our laboratory would be presented.
