Membrane Technology

By Prof. Kaustubha Mohanty   |   IIT Guwahati
Learners enrolled: 642
This course will provide an insight to the membrane based separations that is an integral part of the down-stream processing of various industries. The course begins with introducing the development of membranes and discussing the basics which is followed by detail discussion on membrane materials and their properties. This course then deals with various methods of membrane preparations and their characterization. How separations (transport mechanism) takes places using membranes has been covered extensively. Further, principles of various membrane processes such as reverse osmosis, microfiltration, ultrafiltration, dialysis, liquid membrane, pervaporation etc. has been covered along with their applications in different industries. The course will enable students to develop necessary skills to design appropriate membrane based separation technique as per the need.

INTENDED AUDIENCE : Final year BE/B.Tech., ME/M.Tech./MS and PhD students
