EXPERIMENTAL ANALYSIS OF INDIRECT FREEZE DESALINATION WITH AND WITHOUT MAGNETIC FIELD EXPOSURE

Abstract

A comprehensive understanding of the influence of freeze desalination (FD) parameters on salt reduction is essential to increase the efficiency of the FD process. In this thesis, an experimental setup with a suspension freezing system has been utilized to quantify the weight of influence of different FD parameters on salt reduction through robust parametric analysis. Additionally, external magnetic fields (MF) is introduced to assess the effect of magnetic flux density, the configuration of electromagnets, and electric current type (AC and DC) on salt reduction. Without MF exposure, the results reveal that the rate of cooling below 12 Co (R12-) is the most influential parameter in the process. With MF exposure, the results indicate that (1) the intensity of MF should be compatible with the feed salinity, and (2) the percentage of salt reduction increases when the magnetic flux density and the Lorentz force increase.
