When an alkaline compound dissolves in water it produces hydroxide ions, OH– . These ions are responsible for the alkalinity of the solution.
Because Magnesium Hydroxide Mg(OH)2 provides two hydroxides for alkalinity compared to one with NaOH caustic soda (Sodium Hydroxide), the usage rate for Mg(OH)2 is much less than that required for NaOH.
While AMALGAM-60 is typically more expensive than 50% NaOH on a “price per unit” basis, it is significantly less expensive in use – because every 1.0 lb of 50% NaOH can be replaced by 0.6 lbs of 60% Mg(OH)2 to provide the same number of moles of hydroxide (OH–) for pH neutralization.
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.Enquire now
AMALGAM is non-hazardous and non-corrosive, which makes it easier and safer to handle, making it a perfect caustic soda replacement. Spill is not reportable.
Because magnesium is a macronutrient – it is the core element of chlorophyll (makes everything green!) – it is also beneficial to the environment while sodium is a salinity hazard.
Magnesium also has coagulation properties that sodium does not. This can result in reduced sludge volume and reduced sludge hauling fees.
In this simple benchtop experiment, we will demonstrate that magnesium hydroxide provides more CaCO3 equivalent alkalinity on an equal weight basis when compared to caustic soda, which means less chemical consumption and can result in significant cost savings. Magnesium hydroxide is also non-hazardous and non-corrosive which makes handling safer and easier.

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.
