Abstract: Described herein is a submerged plate membrane device intended for use in forward osmosis processes, particularly for concentrating various process streams such as those in ponds. Particular examples of feed streams that may be concentrated are for example the following feed solutions: brines, seawater, drilling mud, waste water, bio-digestate, and the like. Thus, the process and device described herein are useful for de-watering, and thus concentrating, the content of solar evaporation ponds and drilling mud ponds.

Abstract: The invention provides cosmetic creams containing granular components for cleansing and scrubbing the skin, which contain granules of a salt, in particular sodium or potassium chloride, and which are stable under storage and use conditions. In an embodiment of the invention, no rinsing is required after use. The invention also provides a process for making the cosmetic creams by mixing a solution of a salt, in the amount contained by a solution that is saturated at a temperature not lower than room temperature, with the water soluble ingredients of the cream base, emulsifying the mixture with the components of the oily phase of the cream base to obtain a complete mixture, homogenizing and cooling the complete mixture, adding fragrances and preservatives and optionally additives, and finally adding solid salt particles while continuing to homogenize said mixture.

Abstract: A weightening composition for weightening a molten salt in the refinement of magnesium or magnesium alloys, characterized in that it comprises one or more bromide salts, selected from among NaBr, KBr, MgBr.sub.2 or CaBr.sub.2.

Abstract: A low sodium edible salt composition comprises, based on dry weight of ingredients, 0-50% NaCl, 45-99.5% KCl and at least 0.5% additives, which comprise at least one edible nucleotide monophosphate salt and at least one member other than the nucleotide monophosphate salt selected from the group consisting of low organic acid, low organic acid salt, phosphoric acid, phosphate salt, a magnesium salt, sugar and burnt sugar. The additives have the effect of countering the bitter taste of KCl.

Abstract: A process for producing potassium sulfate, sodium sulfate, and sodium chloride from potash and a sodium sulfate/water source, which includes: (a) treating the sodium sulfate/water source to produce a slurry containing anhydrous sodium sulfate; (b) concentrating the slurry to form a concentrate and a diluent; (c) treating the diluent to precipitate out anhydrous sodium sulfate; (d) subjecting the anhydrous sodium sulfate from steps (b) and/or (c) and/or from a different source to conversion with potash in an aqueous medium to yield glaserite and a first mother liquor, with any excess anhydrous sodium sulfate being taken as co-product; (e) converting the glaserite with potash and water to produce a precipitate of potassium sulfate and a second mother liquor; (f) returning the second mother liquor to step (d); (g) subjecting the first mother liquor to evaporative crystallization such that substantially pure sodium chloride is precipitated in a third mother liquor; and (h) returning the third mother liquor for co

Abstract: A process for producing potassium sulfate or potassium sulfate and sodium sulfate from potash and a sodium sulfate/water source, which includes: (a) subjecting a sodium sulfate source to conversion with potash in an aqueous medium to yield glaserite precipitate and a first mother liquor; (b) converting the glaserite precipitate with potash and water to produce a potassium sulfate precipitate and a second mother liquor; (c) returning the second mother liquor to step (a); (d) subjecting the first mother liquor to treatment, such as evaporative crystallization, such that a sodium chloride and sodium sulfate solids mixture or pure sodium chloride is precipitated in a third mother liquor; (e) subjecting the solids from step (d) to a sodium sulfate/water source to produce anhydrous sodium sulfate; and (f) returning the third mother liquor for conversion to potassium salts.

Abstract: The present invention relates to an improved method for the manufacture of potassium phosphates. More specifically the present invention provides a process for the manufacture of monopotassium phosphate, KH.sub.2 PO.sub.4, from potassium bearing brines.
