Claim 0:
1. A method for desalination of salt water and its analogues by salt-repellent technique, comprising the following steps:
filtering sea water,
deaerating the filtered sea water,
cooling and filtering the deaerated sea water,
blending the clear deaerated filtered cold sea water with a salt-repellent additive,
freezing the blended mixture to obtain a frozen admixture,
centrifuging the frozen admixture to separate crystalline ice and mother liquor, melting the crystalline ice to obtain the first crop of desalted water,
freezing the mother liquor with additional salt-repellent additives,
centrifuging the frozen mother liquor to obtain a second crop of ice crystals, melting second crop of ice crystals to obtain a second crop of desalted water, sending the mother liquor obtained from the second centrifugation to recover all types of dissolved minerals,
wherein, the salt-repellent additive contains a single chemical product or consists of a mixture of surface-active agents, amino acids, alcohols, esters, ketones and chemical reagents, wherein the salt water and its analogues include waters containing inorganic salts from sea water, retentate water of reverse osmosis unit, nano water, produced water, brackish water, brine, ground water, impure waters, industrial effluent waters, lake water, municipal waste water, polluted water, Red Sea water, river or other stream water, salt water, and all types of waste water containing inorganic salts.
