Prevent Corrosion with Magnesium Hydroxide
Magnesium hydroxide (Mg(OH)₂) is a highly effective solution for combating corrosion in wastewater treatment systems. Corrosion is a significant issue in wastewater infrastructure, primarily due to the presence of acidic and aggressive environments caused by sulfide gases, low pH levels and microbial activity. By leveraging the unique properties of magnesium hydroxide, wastewater treatment facilities can improve the longevity and efficiency of their systems.
One of the key benefits of magnesium hydroxide is its ability to neutralize acidity. It acts as a buffering agent, raising the pH of wastewater and creating an environment that is less conducive to the formation and release of hydrogen sulfide (H₂S), a primary contributor to corrosion. By maintaining a pH level above 8.0, magnesium hydroxide converts problematic H₂S gas into non-odorous sulfides, thereby minimizing its corrosive impact on pipes, tanks, and other infrastructure.
Magnesium hydroxide also has antimicrobial properties that inhibit the growth of sulfate-reducing bacteria (SRB), which are responsible for converting sulfates into corrosive sulfides. This dual action of pH control and microbial inhibition significantly decreases the rate of biogenic sulfide corrosion, which is a common challenge in wastewater treatment systems.
Magnesium hydroxide is environmentally friendly and safe to handle. Unlike some chemical alternatives, it does not introduce toxic byproducts into the environment, does not produce excess solids that increase disposal costs, and is non-hazardous to operators.
Wastewater treatment facilities should know that not all magnesium hydroxide is created equally. Premier Magnesia’s 60% magnesium hydroxide slurry is the most concentrated form of consistent and reliably superior aqueous alkalinity commercially available. It is more chemically robust than competing products and can deliver more consistent results at lower dosage rates, leading to cost savings and increased efficiency.
By incorporating magnesium hydroxide into wastewater treatment processes, facilities can achieve significant cost savings through reduced infrastructure repair and replacement, improved operational efficiency, and enhanced environmental compliance. As the industry continues to seek sustainable solutions, magnesium hydroxide stands out as a reliable and versatile option for corrosion prevention.
