Water treatment applications involve MgO playing important roles in waste removal processes. It aids in the collection and precipitation of removed particles, organic matter, and heavy metals, acting as a coagulant and flocculant.
With the addition of magnesium oxide, the formation of larger flocs is supported, making it easier for unwanted particles to separate from the water during settling or filtration.
This application facilitates the removal of oil, grease, and various pollutants found in industrial, municipal, or agricultural wastewater streams.
Additionally, the alkaline properties of magnesium oxide facilitate the precipitation of phosphorus by reducing its concentration in treated water, thus enabling cleaner and safer water discharge.
