Solar-driven membrane distillation with direct ambient-temperature feed heating

The dataset was used in the scientific article entitled "Solar-driven membrane distillation with direct ambient-temperature feed heating: design, modeling, and experimental validation", available at https://doi.org/10.1016/j.desal.2025.119660 The dataset contains the experimental characterization of a solar-driven membrane distillation system with direct ambient-temperature feed heating. It includes measurements of mass flow rate, temperature, permeate electrical conductivity, and mass evolution profiles used to calculate the distilled water production. The main file, provided in Excel format, contains steady-state data. The first sheet summarizes the key parameters used for system characterization, while the second sheet includes a schematic diagram and numerical values describing the laboratory conditions under which the experiments were conducted.
