Calix Water Business in North America is IER (www.ierwater.com).
IER offers Magnesium Hydroxide-based products as safe, earth-friendly alternatives to the use of caustic soda for pH neutralization, along with proprietary polymer solids removal technologies.
- Feel you are paying too much for your alkali?
- Looking at a safer alternative to caustic soda for pH control in your nitrification process?
- Want a greener alkaline additive for your wastewater treatment?
A safer, greener and more cost effective alternative to caustic soda
ACTI-Mag has a higher neutralising value per kilo when compared with caustic whilst being significantly safer to handle than other traditional alkalis, making it a very safe and cost competitive option.

Better for your budget
While Magnesium hydroxide Mg(OH)2 is typically more expensive on a “price per unit” basis, it is significantly less expensive in use.
Every 1.0 kg of 50% NaOH can be replaced by 0.6 kg of 60% Mg(OH)2 to provide the same number of moles of hydroxide (OH-) for pH neutralization.

Better for your system
Magnesium hydroxide Mg(OH)2 (unlike sodium hydroxide NaOH) has coagulation properties. This means:
- more solids content of sludge on dewatering device
- less sludge volume
- less sludge hauling fees
More alkalinity
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, the usage rate for Mg(OH)2 is much less than that required for NaOH.
