Options to develop tanning industries could be hindered even in the presence of huge leather industry raw materials due to the requirements of high-tech contaminant removal technologies, especially in developing countries. This study was initiated to investigate the efficiency of freeze desalination for Cr(VI) removal using freezers to generate fresh water. Simulated water as well as deionized water to which known concentrations of Cr(VI) spiked into it were studied. The effects of parameters such as initial concentration, freeze duration, ice nucleation, ice volume, and influence of co-occurring ions were evaluated in relation to meltwater. The physicochemical characteristics of the produced meltwater were also evaluated. A high total water recovery of up to 85% V/V of initial water was achieved for the freeze separation rate of 90% in the experimental evaluation. Cr(VI) removal efficiency of up to 80% from simulated tap and 93 to 97% for deionized water spiked with Cr(VI) were found in this batch partial freezing. Freeze desalination was found to be relatively viable desalination technology in terms of quality of water produced, options on the use of cost effective refrigerants and technologies which could have a pertinent importance to save energy consumption of freezers.
