Fouling Mitigation in Membrane Distillation Using Pulsation Flow Technique

The main obstacles to scaling up membrane distillation (MD) on a commercial level are fouling and temperature polarization. Therefore, in this study, the significance of pulsation feed flow phenomenon was used for (DCMD) polarization, comparisons were made using steady-state flow. Two different Hertz amplitudes trends DCMD sources water, including distilled seawater, wastewater. Compared flow, results revealed that flux enhanced seawater once operating became turbulent, it even more rate increased turbulence moved. For wastewater, had an impact delaying beginning decline point enhancing overall freshwater recovery. In both flows (1 2 Hertz), also deficiency improvement distribution channel desalination wastewater running under typical operational conditions. Taking value into consideration, enhancement mass (~5–10%) observed compared Moreover, channels found reduce CPC by about 10–15%, proving role mixing mitigating reduction concentration
