Lime and soda-ash softening of reclaimed water reverse osmosis concentrates as a pretreatment step for concentration by seawater reverse osmosis was the focus of this study. The objectives were removal of the potential fouling minerals of calcium, magnesium, and silica by selective precipitation, while producing byproducts with potential resale value. Three different bench-scale lime-soda processes were evaluated. The traditional method produced low-quality magnesium hydroxide [Mg(OH)2] and… CONTINUE READING
