Magnesium hydroxide (Mg(OH)₂) is an inorganic compound widely recognized for its applications across environmental, chemical, pharmaceutical, and industrial sectors. Appearing as a white, crystalline, or fine amorphous powder, it is known for its basic (alkaline) nature and moderate reactivity. In its naturally occurring form, it is found as the mineral brucite, though industrial production typically involves precipitation reactions between magnesium salts (like magnesium chloride) and alkaline substances (like sodium hydroxide). Magnesium hydroxide acts primarily as an antacid, flame retardant, pH regulator, and neutralizing agent, making it a versatile compound with broad commercial significance.

From a market definition standpoint, magnesium hydroxide is often categorized according to its application-specific grade—industrial, pharmaceutical, or environmental. The industrial-grade magnesium hydroxide is used extensively in wastewater treatment, flue gas desulfurization (FGD), flame retardants, and in the production of magnesium-based chemicals. It plays a critical role in neutralizing acidic wastewater, precipitating heavy metals, and maintaining regulatory compliance for discharge standards.

Magnesium hydroxide slurry, which is recognized as "the milk of magnesia" for wastewater treatment, has been widely utilized for heavy metal precipitation and acid neutralization of industrial wastewater. Many industrial and municipal wastewater facilities are now converting over to magnesium hydroxide for utilization in aerobic and anaerobic biological treatment systems.

Market growth for magnesium hydroxide for Water Treatment is being shaped by several macroeconomic and regulatory trends. Environmental regulations are among the strongest drivers, particularly in developed regions such as North America, Europe, and parts of East Asia, where there is mounting pressure on industries to treat effluents effectively and reduce harmful emissions. In this context, magnesium hydroxide offers a safe and cost-effective solution for pH control, heavy metal precipitation, and odor control in municipal and industrial wastewater treatment.

Global Magnesium Hydroxide for Water Treatment key players include Ube Materials, Martin Marietta, Huber Engineered Materials (HEM), Yantai FR Flame Technology, Qinghai West Magnesium, etc. Global top five manufacturers hold a share about 50%. China is the largest market, with a share about 30%, followed by Japan and Europe, both have a share over 45 percent.
