AbstractThis research focuses on the use of vacuum membrane distillation (VMD) for seawater desalination. The aim of the work is to estimate the following operating parameters: progression of salt concentration and rejection rate of retentate in the membrane module. The mathematical equations are derived from the energy and mass balances. The solar collector field surface is 70 m2. A solar system is used to ensure the heating of seawater. The production of electrical energy required to operate the unit is guaranteed by photovoltaic cell panels. The distillate flow rate attains maximum value on a typical summer day: 21 June (782 kg).
