Treatment of uranium containing effluents with reverse osmosis process

Uranium removal from groundwater by natural clinoptilolite zeolite: Effects of pH and initial feed concentration

“…However, it generates concentrated liquid wastes that must be disposed of. Other methods for removing uranium include chemical clarification that uses ferric sulfate or aluminum sulfate [5], precipitation [6], membrane filtration [7], and reverse osmosis [8]. The major limitation for these methods is the proper disposal of the resulting sludge that contains high levels of the metal and other contaminants.…”

Enhanced U(VI) removal from drinking water by nanostructured binary Fe/Mn oxy-hydroxides

“…Nevertheless, this method generates concentrated liquid wastes that must be appropriately disposed, thus, increasing the overall operational costs [12]. Membrane methods, such as nanofiltration [13] and reverse osmosis, are also efficient for uranium removal, removing the carbonate uranium complexes by more than 90%, but their application requires experienced personnel and their use is quite expensive, especially when designed for treatment of relatively small volumes of water [9,14,15].…”

Adsorption of Neodymium(III) on Acrylic Resin (110 Resin) from Aqueous Solutions

“…Different methods, for instance, chemical precipitation (9), evaporation (10), reverse osmosis (11), and solvent extraction (12) have been proposed for separation and uptake of REEs. Most of them share problems of miscellaneous steps, huge energy consumption, and high cost of equipment.…”
