Magnesium Hydroxide For Neutralization Of Acidic Wastewater

1. Safe and Controlled pH Adjustment

• Gradual neutralization: Dissolves slowly, preventing over-neutralization (pH spikes) and ensuring stable pH control.

• Optimal pH range: Effectively neutralizes acidic wastewater (pH 2–6) to a safe discharge level (pH 7–9) without excessive alkalinity.

• Reduced corrosion risk: Unlike caustic soda (NaOH), Wastewater treatment grade Magnesium Hydroxide minimizes pipe and equipment corrosion.

2. Heavy Metal Removal & Precipitation

• Co-precipitation: Non-toxic Magnesium Hydroxide Reacts with dissolved metals (e.g., Pb, Cu, Cd, Zn, Ni) to form insoluble hydroxides, facilitating removal via sedimentation/filtration.

• Superior to lime (CaO): Non-toxic Magnesium Hydroxide Generates denser, more stable sludge with lower disposal costs.

• Arsenic & fluoride removal: Non-toxic Magnesium Hydroxide Effective in precipitating As, F⁻, and other anions when combined with iron salts.

3. Lower Sludge Volume & Disposal Costs

• Produces 50–70% less sludge compared to lime (Ca(OH)₂).

• Sludge is more compact, dewaterable, and non-hazardous (passes TCLP tests).

• Reduces landfill costs and environmental liability.

4. Buffering Capacity & Long-Lasting Effects

• Wastewater treatment grade Magnesium Hydroxide Maintains stable pH even with fluctuating acidic inflows (unlike NaOH, which requires continuous dosing).

• Wastewater treatment grade Magnesium Hydroxide Resists pH rebound in systems with CO₂ ingress (common in biological treatment).

5. Environmentally Friendly & Sustainable

• Non-toxic & biodegradable: Non-toxic Magnesium Hydroxide Safer for aquatic life compared to caustic chemicals.

• No secondary pollution: Non-toxic Magnesium Hydroxide Does not release harmful byproducts (e.g., chlorides from HCl neutralization).

• Cost-efficient: Lower dosage requirements than lime or soda ash.
