Every 1.0 lb of 50% NaOH can be replaced with 0.60 lbs of 60% Mg(OH)2 to provide the same number of moles of hydroxide (OH-). This 40% reduction in daily usage rate translates into a dramatic cost savings – for something that is “green” and safe!
50% NaOH freezes at 60ºF, so in winter 25% NaOH is commonly used. 60% Mg(OH)2 freezes at 32ºF, just like water, greatly minimizing freeze concerns.
Mg(OH)2 can provide improved solids settling and sludge compaction benefits that NaOH does not. When Mg(OH)2 dissolves, the Mg2+ cation can coagulate suspended solids to improve both microorganism activity and solids removal efficiency – often reducing polymer usage.
GREEN Magnesium is the core element of chlorophyll (what makes plants green), while salinity from Sodium is detrimental, especially for land reuse applications.
AMALGAM-60 (60% Mg(OH)2) has a higher neutralizing value per pound than any other alkaline additive. This translates into a 40% reduction in chemical usage when compared with caustic soda, while being significantly safer for operators to handle and more nutritive for the microorganisms being maintained – making it the most cost-effective option.
