Malini Balakrishnan
Adjunct Faculty,
Department of Energy and Environment

Dr Balakrishnan's major interests are development and dissemination of environmentally sound technologies, with emphasis on membrane development and applications. She has directed various externally funded projects involving international consortia, as well as projects with industrial applications and is also active in developing and effecting technology transfer of membrane processes and products to industry. Dr Balakrishnan's research has evolved around (a) Microfiltration /ultrafiltration / pervaporation process development (b) new membrane materials (c) value-added utilization of wastes. Primarily, the work is targeted at providing solutions to specific problems with strong local relevance (e.g. advanced wastewater treatment) and is associated with addressing the concerns of major Indian industries (e.g. sugar factories for improved clarification in sugar production process, new applications of waste bagasse fly ash). The work on preparation and application of ceramic membranes from waste biomass fly ash is an example of making membranes more affordable for various solid-liquid and solid-gas separations. The research activities are primarily directed at users needs with doctoral and masters students concurrently contributing to advancing the state-of-the-art in these fields. She has over 90 publications in journals and conferences to her credit and four patents under processing.
