Indigenous ceramic membranes for degumming and solvent recovery
The objective of this study is to prepare, characterize and test low cost ceramic ultrafiltration (UF) and nanofiltration (NF) membranes for vegetable oil refining application. The ceramic membranes will be based on biomass fly ash macroporous supports (that have already been developed by TERI). Different separation layers will be prepared using methods like tapecasting, sol-gel coating of Al2O3 or SiO2 sols, to obtain UF/NF membranes of various pore sizes. The membrane properties would be characterized in detail and appropriate membranes would be tested for degumming and solvent recovery applications.
The expected project outcomes are: (a) process for low cost ceramic membrane preparation and (b) results on the suitability of these indigenous membranes for vegetable oil degumming and solvent recovery applications.
