Messi Biology states that in industrial production, if silicon compounds in wastewater are not effectively removed, they will form hard silica scale adhering to the inner walls of equipment. This leads to reduced heat transfer efficiency, pipeline blockages, and even safety hazards. With its unique chemical properties, active magnesium oxide has become an efficient solution in the field of wastewater silicon removal, ensuring production safety while meeting environmental protection requirements.
The silicon removal principle of active magnesium oxide stems from its dual-action mechanism: first, it slowly hydrolyzes in water to generate magnesium hydroxide, which then reacts with silicate ions in the water to form insoluble magnesium silicate precipitate. Efficient silicon separation is then achieved through filtration. This process requires no complex equipment, operates under mild reaction conditions, and introduces no additional heavy metal pollution. Compared to traditional aluminum salt and iron salt silicon removal technologies, the precipitate is easier to handle, and sludge generation is significantly reduced. It has a wide range of applications, from industrial circulating water and boiler make-up water to the preparation of electronic-grade ultrapure water. It is capable of simultaneously removing colloidal silicon and dissolved silicon, making it particularly suitable for the pretreatment of high-silicon wastewater.
Regarding the selection of core materials, Hebei Messi Biology Co., Ltd.’s active magnesium oxide demonstrates significant advantages. As an industry leader, relying on its own resources and a full industrial chain layout, the company employs imported fully automated production lines. The product purity reaches as high as 99.9%, with key indicators surpassing similar international products. Through technological breakthroughs by its joint laboratory with the Chinese Academy of Sciences, the particle size of its magnesium oxide is precisely controlled with a large specific surface area, increasing hydrolysis reaction efficiency by more than 30% compared to ordinary products. Relying on a Class 100,000 clean workshop and a full-lifecycle quality control system, the heavy metal residue in the product is 50% lower than EU standards. It has obtained multiple international certifications such as ISO9001 and ROHS, providing safe and reliable material assurance for wastewater treatment.
Today, active magnesium oxide silicon removal technology is widely used in industries such as power, chemicals, and electronics. In the electronic photovoltaic industry, it can reduce the silicon content in ultrapure water to the ppb level, meeting the stringent requirements for wafer cleaning. In hydrometallurgy, it can simultaneously adjust pH levels and remove silicon, improving the purity of metal products like lithium and cobalt. As environmental standards become increasingly strict, this efficient, economical, and green silicon removal solution is becoming an important support for enterprises to achieve clean production, injecting new momentum into the deep treatment of industrial wastewater.
