Membrane distillation (MD) is an evolving thermal separation technique most frequently aimed at water desalination, compatible with low-grade heat sources such as waste from engines, solar collectors, and high-concentration photovoltaic panels. This study presents a comprehensive theoretical–experimental evaluation of three commercial membranes different materials (PE, PVDF, PTFE), tested for two distinct MD modules—a Direct Contact Distillation (DCMD) module Air Gap (AGMD) module—analyzing the impact key operational parameters on performance individual in each configuration. The results showed that increasing feed saline concentration 7 g/L to 70 led distillate flux reductions 12.2% DCMD 42.9% AGMD one, averaged over whole set experiments. increase temperature 65 °C 85 resulted fluxes up 2.36 times higher 2.70 one. PE-made membrane demonstrated highest fluxes, while PVDF PTFE exhibited superior under high-salinity conditions module. Membranes high contact angles, 143.4°, performed better salinity conditions. Variations parameters, flow rate temperature, markedly affect polarization effects. analyses underscored necessity careful selection type configuration by specific characteristics process its In addition experimental findings, proposed mass transfer-reduced model good agreement data, deviations within ±15%, effectively capturing influence parameters. Theoretical predictions confirming model’s validity, which can be applied optimization methodologies improve process.
