GOOD REPORT ABOUT PRACTICAL WAYS OF CLEANING WATER TO BE “GOOD ENOUGH” FOR INDUSTRIAL USE. WOULD REFRIGERATION–AS REQUIRED FOR WATER CRYSTALLIZATION–BE ENERGY EFFICIENT IN AREAS WHEN IT HAS TO BE USED?

A Finnish University recently discovered the benefits of crystallization, or freezing water in order to purify it. Essentially, these scientists found that the upper layer of ice from a lake in Finland was nearly ten times cleaner than the water beneath. In addition, ice that had formed more slowly was noticeably cleaner than rapidly formed ice. This event called crystallization can only occur with the presence of a solvent and solute, such as water and salt. A professor from Lappeenranta University of Technology (LUT) made the statement below regarding the study.
