Introduction to Ceramics

Dr. Chandan Das is Professor in the Department of Chemical Engineering at Indian Institute of Technology Guwahati (IITG). He has received his PhD in Chemical Engineering from Indian Institute of Technology, Kharagpur (IITKGP). He has guided, so far, 12 scholars for their doctoral degree, 32 M.Tech. and is guiding 5 more doctorate scholars. He has authored four (4) books and eleven (11) book chapters. He has three (3) patents in his credit. He has handled nine sponsored projects and seven consultancy projects up to now. He has visited Denmark, Malaysia, Sri Lanka, Japan, Greece, and Athens for exchanging ideas, etc. His major research areas include (i) Membrane Based Separation Technology, (ii) Food Engineering, (iii) Biomedical, (iv) Material Science; (v) Corrosion, (vi) Wastewater Treatment and (vii) Simulation and Modelling.

Being associated with various research works in the area of water and wastewater treatment, such as treatment of tannery wastewater using membrane separation technology, as well as removal of pollutants using micellar-enhanced ultrafiltration, Dr. Das has gained expertise in membrane separation technology for removing various pollutants from contaminated water and wastewater. His research activity encompasses both understanding of fundamental principles during filtration as well as the development of technology based on membrane separation. In particular, his research areas are modeling of microfiltration, ultrafiltration, nanofiltration, reverse osmosis, treatment of oily wastewater, tannery effluent using membrane-based processes. He has explored the detailed quantification of flux decline from fundamentals. As an offshoot of the major research, he has fabricated ceramic membranes using low cost precursors as sawdust. Catalyst is coated on the ceramic support for manufacturing catalytic membrane reactor.

He is also working on decontamination of chromium laden aqueous effluent using Spirulina platensis. He is actively involved in the productions of high value-added products, namely, total phenolics, flavonoids, tocopherol, etc. from black rice as well as of 6-gingerol, vitamin C content, essential oil content from ginger of North East India.

He is a Fellow of Royal Society of Chemistry, UK, and Fellow of Indian Institute of Chemical Engineers. He is subject coordinator for PMRF, Govt of India. He is coordinator for International joint master degree program (IMFST) with Gifu University, Japan. He is liaison from IIT Guwahati for Ministry of Education, Culture, Sports, Science and Technology (MEXT) project, Japan.
