Magnesium Hydroxide
Neutralization without the overshoot.
Magnesium hydroxide's low solubility is precisely why treatment plants choose it. It cannot drive pH much above roughly 9, so it neutralizes acid steadily and self-limits — where an overdose of caustic soda or lime can spike a discharge out of permit in minutes. It also produces a denser, more easily dewatered sludge.

Principal Industrial Uses
Where it's used, and why.
Industrial Wastewater
Neutralizes acidic waste streams and precipitates heavy metals without the pH overshoot risk of caustic soda, producing denser, faster-settling sludge.
Flue Gas & Emissions
Scrubbing reagent for SO₂ and acid gas removal in industrial emission control systems.
Municipal Treatment
Alkalinity supplementation and odor and corrosion control in collection systems and treatment plants.
