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.
While ACTI-Mag is typically more expensive then 50% NaOH on a “price per unit” basis, it is significantly less expensive in use – because every 1.0 kg of 50% NaOH can be replaced by 0.6 kgs of 60% Mg(OH)2 to provide the same number of moles of hydroxide (OH-) for pH neutralization.
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.Enquire now
Unlike caustic soda, ACTI-Mag is non-hazardous and non-corrosive, which makes it easier and safer to handle. 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.
