  Magnesium Oxide (CAS 1309‑48‑4) is a high-activity functional inorganic powder widely applied in industrial wastewater treatment and environmental protection engineering fields. Our export-standard magnesium oxide adopts high-quality raw materials and precise calcination processing technology, maintaining MgO purity above 92.0%, with strictly limited calcium oxide impurities and ultra-low moisture content. The finished white loose powder features fine and uniform particle size ranging from 200 mesh to 800 mesh, outstanding fluidity and water dispersibility, which can be fully dissolved and mixed in sewage without precipitation or agglomeration, ensuring full play of chemical activity.

  This high-purity magnesium oxide has three core functional advantages in water treatment. Firstly, it serves as an efficient pH regulator, able to moderately neutralize acidic industrial wastewater, stabilize water body pH within the qualified discharge range, and avoid equipment corrosion caused by acid-base imbalance. Secondly, it delivers excellent phosphorus removal performance, reacting with phosphate substances in sewage to form insoluble precipitates, effectively reducing total phosphorus content in water and solving the problem of water eutrophication. Most importantly, it has strong adsorption capacity, which can firmly capture and fix various residual heavy metal ions in wastewater and sludge, realizing harmless treatment of polluted water bodies.

  Compared with traditional water treatment chemicals, magnesium oxide features mild reaction, no secondary pollution and long-term stable treatment effect, significantly improving sewage purification efficiency and reducing enterprise water treatment costs. It is widely suitable for various industrial wastewater purification and sludge reduction treatment scenarios. All our products pass strict quality inspection, with stable composition and consistent performance across batches. Supported by sufficient inventory and mature global export supply chain, we provide long-term stable bulk supply and cost-effective solutions for global environmental protection companies, industrial manufacturing enterprises and sewage treatment plants.
