Development of mass and heat transfer coupled model of hollow fiber membrane for salt recovery from brine via osmotic membrane distillation

Abstract Background In this research work, a coupled heat and mass transfer model was developed for salt recovery from concentrated brine water through an osmotic membrane distillation (OMD) process in hollow fiber contactor (HFMC).The built based on the resistance-in-series concept transport across hydrophobic membrane. The adopted to incorporate effects of polarization layers such as temperature concentration polarization, well viscosity changes during concentration. Results modeling equations were numerically simulated MATLAB® successfully validated with experimental data literature deviation within range 1–5%. then applied study key parameters like feed concentrations, solution concentration, feed, flow rates overall coefficient flux improve efficiency. balance calculate area coefficient. Finally, scale-up MD industrial scale proposed. Conclusions This highlights effect wastewater using process. Further, applicability OMD large investigated. Sensitivity analysis performed identify parameters. From results study, it is concluded that can be promising wastewater.
