A safe and cost-effective alternative to the use of sodium hydroxide [caustic soda, NaOH]
for wastewater alkalinity and pH adjustment
AMALGAM-60 is a proprietary, concentrated aqueous suspension of magnesium hydroxide (hydrated lime of magnesia – Mg(OH)₂) produced from calcined, high purity, natural magnesite. This product is manufactured in Washington state using a proprietary blend of dispersants that result in optimum storage stability and reactivity.
AMALGAM-60 provides a highly reactive source of magnesium hydroxide (Mg(OH)2) for use in chemical processing, water treatment, and wastewater treatment applications. AMALGAM-60 offers a safe, non-hazardous means of effective acid neutralization, coagulation, H₂S and heavy metals removal in wastewater and process streams.

KEY BENEFITS OF USING MAGNESIUM HYDROXIDE INSTEAD OF CAUSTIC SODA:
1 => Cost
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!
3 => Freezing
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.
2 = > Solids Settling
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.
4 => Earth-friendly
GREEN Magnesium is the core element of chlorophyll (what makes plants green), while salinity from Sodium is detrimental, especially for land reuse applications.
Switch to AMALGAM-60 and save thousands of dollars!
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.
