Process intensification using hollow fibre-supported liquid membranes (HFSLMs) has been studied in the present work. The importance of use of HFSLM is highlighted over the other conventional available methods for separation. The present study focuses mainly on the recovery of acids and metal ions from dilute aqueous waste streams. The solute (acids or metal ions) flux through hollow fibre contactor measured under different operating conditions. The HFSLMs have been compared with conventional separation techniques, such as solvent extraction, ion exchange, etc., to highlight the process intensification potential. |
