AMALGAM-60

A safe, environmentally-friendly, and cost-effective alternative to the use of Sodium Hydroxide (Caustic Soda, NaOH) for wastewater pH and alkalinity control.

Download the product data sheet Calculate Your Savings

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.

Product Application

  • 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.

Chemical Composition

Packaging and Handling

  • Product should be protected from freezing.
  • Agitated storage is required.
  • Select a feed pump that is capable of reliable delivery of a slurried material.
  • If the product is to be fed intermittently, periodically provide flushing water in order to minimize the risk of slurry deposition within the pump head or feed lines.
  • AMALGAM-60 is manufactured in the Pacific Northwest and the Midwest, and is available in packaging from totes to full truckload deliveries.

Key benefits

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.

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!

Green

Magnesium is the core element of chlorophyll (what makes plants green), while salinity from Sodium is detrimental, especially for land reuse applications.

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.

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.

Safety

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.

Trial Equipment

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.

SUPPORTING WATERAID

Because we truly care about sanitation

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.
