Dr. Chandan Das is a 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) after completing his B. Tech and M. Tech in Chemical Engineering from University of Calcutta. He has guided, so far, 10 scholars for their doctoral degree, 28 M.Tech. and is guiding 8 more doctorate scholars. Dr. Das is the recipient of "Dr. A.V. Rama Rao Foundation's Best Ph.D. Thesis and Research Award in Chemical Engineering/Technology" for the year 2010 from Indian Institute of Chemical Engineers (IIChE). Dr. Das has authored about one hundred fifty technical publications in peer reviewed journals and proceedings. He has authored four books entitled "Treatment of Tannery Effluent by Membrane Separation Technology" in Nova Science Publishers, USA, and "Advanced Ceramic Membranes and Applications", “Polymeric Membrane Synthesis, Modification and Applications: Electro-spun and Phase-inverted Membranes” and “Polymeric Membrane Synthesis, Modification and Applications: Electro-spun and Phase-inverted Membranes” in CRC Press, USA and six book chapters. He has two patents in his credit. He has handled seven sponsored projects and seven consultancy projects so far. He has visited Denmark, Malaysia, Sri Lanka, Japan and, Greece for exchanging ideas, etc. 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.
