Magnesium Hydroxide for Wastewater Treatment

Because of the composition characteristics of brucite, it can be used for acid wastewater neutralization treatment. It not only in many aspects than the traditional alkali material (such as sodium hydroxide, calcium hydroxide, etc.) has the advantage of the process, and in the product treatment and discharge can greatly reduce the cost.  The use of magnesite ore and its calcined product as neutralizing agent is the most widely used field of medium and low grade magnesite. Because of the buffering properties of magnesium hydroxide or magnesium oxide, the PH value can always be maintained in the process of operation at about 9, even if the excessive PH value will not exceed, and easy to master, can be widely used in the petrochemical industry in the treatment of acidic wastewater, waste liquid, adjust the soil acid-base balance (adjust PH value), adsorption of heavy metals.
