- An approach for recovery of used seawater After reacting magnesium metal with citric acid to produce hydrogen gas and precipitating magnesium as magnesium gluconate, the remaining water is desalinated using the reverse osmosis technique. Magnesium gluconate was prepared as a medication product under ordinary conditions and is soluble in water. A spiral wound Reversed “Osmosis” commercial membrane module was used in prototype unit. Different concentrations of remediated seawater were mixed to create the necessary water salinities for spinach irrigation in rural areas with no other source of water. Irrigation results showed that 1000 ppm, 650 ppm, and 350 ppm almost gave the best treatments with fresh, dry, weight, and NPK when compared to 150 and 200 ml.
