Magnesium Hydroxide Slurry Cost Savings

Magnesium Hydroxide Slurry Provides Cost Savings Over Caustic Soda and Hydrated Lime in Wastewater Treatment

Magnesia-based technologies are trusted by many of North America’s major corporations for wastewater neutralization, pH adjustment, and alkalinity supplementation by delivering a compelling envelope of technical, economic, and safety benefits.

An important source of cost savings available to 50% caustic soda users originates from the greater alkalinity contribution of magnesium hydroxide:

  • One gallon of magnesium hydroxide slurry replaces 1.7 gallons of 50% caustic soda on an equal-alkalinity basis
  • One gallon of magnesium hydroxide slurry replaces 2.8 gallons of 34% hydrated lime slurry on an equal-alkalinity basis

Additional cost reductions with magnesium hydroxide slurry include:

  • Disposal costs of biosolids/sludge creates less sludge volume vs. caustic soda and hydrated lime
  • Costs for acids are unnecessary with natural buffering at a pH of 9
  • Costs for descaling chemicals - magnesium hydroxide does not cause scaling like hydrated lime
  • Costs for polymers – magnesium hydroxide forms a larger floc particle than caustic soda where solids settling is improved, reducing polymer usage
Reduced transportation costs - Consuming less neutralization agent means less product to transport
