Industrial-Grade Magnesium Hydroxide: A Cost-Saving Alternative for Large-Scale Wastewater pH Adjustment

For large industrial clients facing soaring caustic soda costs and unstable pH control in wastewater treatment, magnesium hydroxide delivers a game-changing solution. Every 0.6 pounds of 60% Mg(OH)₂ can replace 1 pound of 50% sodium hydroxide to release the same amount of hydroxide ions, cutting daily chemical consumption by 40% and reducing overall operational costs significantly. Unlike caustic soda that causes sharp pH spikes, it dissolves only when encountering acidity, maintaining a stable buffering range that protects microbial activity in biological treatment systems. This eliminates the frequent over-adjustment errors that have long troubled large municipal water plants and manufacturing groups, while also lowering the risk of operator burns from highly corrosive liquids.
