  • Patent number: 11945743
    Abstract: A novel Salt Repellent Technique is presented to remove all inorganic salts from seawater to get potable water. The repellent additives recommended throws out all salts of sodium, magnesium, calcium, potassium and the like ions from seawater and paves way to get salt free potable water. The conventional washing of ice crystals is completely avoided due to the presence of additives. This technique helps to remove last traces of salts from seawater and analogous waters, without undertaking the conventional washing process. The new salt repellent process assures of high water recovery, ease of operation, lesser pollution, smaller plants, simpler machinery and technology, lower energy cost, nil or lesser pre-treatment and recovery of valuable by-products. To reduce the TDS still lower, it is recommended to have a simplified reverse osmosis unit in addition, as a post-operative arrangement.
