AMALGAM-60 is a proprietary, concentrated aqueous suspension of magnesium hydroxide (hydrated lime of magnesia) 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.
Magnesium Hydroxide (Mg(OH)2) is a safe, environmentally-friendly, and cost-effective alternative to the use of Sodium Hydroxide (Caustic Soda, NaOH) for wastewater pH and alkalinity control.
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!
Magnesium is the core element of chlorophyll (what makes plants green), while salinity from Sodium is detrimental, especially for land reuse applications.
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
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.
Though Mg(OH)2 is much stronger for supplying OH- buffering, it is dramatically safer for operators to handle and for treating wastewater microorganisms. Mg(OH)2 dissolves only when it encounters acidity, unlike NaOH which immediately releases OH- to burn operator’s skin and eyes. This is why the pH can rapidly spike to > 12 if Caustic is overfed, while the overfeed of Mg(OH)2 will safely buffer the pH up to 8 or 9. This “controlled release” trait of Mg(OH)2 is a primary driver for its acceptance as an ideal buffering agent for nitrification and anaerobic digestion processes.
IER supplies agitated storage tanks (from 175 to 1600 gallons) to allow real-time measurement of cost savings while confirming performance, safety, and feed reliability – allowing a clear understanding about how Mg(OH)2 will improve your overall system before deciding to make a permanent transition. IER supplies AMALGAM-60 in full tanker or small volume quantities using dedicated, in-house delivery specialists and equipment.

Almost 2 billion people do not have a decent toilet or access to basic and safely managed sanitation. In many cases, faeces and urine end up untreated in the environment, contaminating it and threatening people’s health.
This is why IER supports WaterAid programs, to facilitate access to safe water, sanitation and hygiene in the world’s poorest and most marginalised communities.
