FREEZE-DESALINATION TESTS USING A SLURRY ICE MAKER.

Author(s) : SHONE R. D. C., GOUWS M. A.

Summary

AN IMPORTANT PART OF COMRO'S RESEARCH IS THE FEASIBILITY OF THE PRODUCTION OF A DESALINATED ICE SLURRY USED FOR COOLING AND FOR THE DESALINATION OF MINE WATER. THE ICE CRYSTALS ARE PURE BUT THE SALTS WHICH ADHERE TO THE SURFACES MUST BE REMOVED BY WASHING. DURING PREVIOUS TESTS ON A PILOT PLANT PROBLEMS WERE EXPERIENCED WITH THE WASHING OF ICE. THE RESULTS INDICATE THAT THE COMPOSITION AND SALT CONCENTRATION OF THE WATER SIGNIFICANTLY INFLUENCE THE SIZE OF THE CRYSTALS AND THEREFORE THE WASHING PROCESS. EFFECTIVE WASHING OF CRYSTALS FROM SOME WATERS MAY REQUIRE THAT THE CRYSTALS BE ENLARGED IN A SEPARATE GROWTH PROCESS.
