the activity of Ca2+ and Mg2+. Softening agent is a kind of water treatment agent for hard water. The mechanism of softening water is reaction with Ca2+ and Mg2+ through complexation or chelation... particles, and affect the recovery and A/S of concentrate. The mechanism of the softening agent is considered that the oxygen atoms of softening agent molecule react with Ca2+ and Mg2+ prior to the breaking......
