Magnesium Hydroxide role in Polymer reduction

When Magnesium Hydroxide is added to a wastewater stream it’s most obvious benefit is to increase the pH and Alkalinity through the controlled release of hydroxide (OH).  Less obvious are the coagulation benefits provided by the divalent Magnesium cation (Mg2+).

The higher the charge (valence) on any ion, the higher the charge density of that ion.  An increase in charge density makes it more like a magnet,  giving the ion a strong ability to draw negative charged particles towards it.  This attraction between positive and negative ions is what leads to enhanced coagulation.

The effect of increasing charge density is shown with the decreasing sizes of the sodium (Na+), magnesium(Mg2+) and aluminum (Al3+) ions.  Due to it’s large size and low charge, the sodium ion (Na+) does not possess coagulation properties.  Alternatively, the aluminum ion (Al3+) has a high charge density making it very usefully as a coagulant, in such products as alum and poly aluminum chloride.

The charge density of the magnesium ion (Mg2+) is between that of Na+ and Al3+, resulting in many wastewater applications that show coagulation benefits.  In such instances, the customers enjoy both cost savings from replacement of caustic soda, as well as a reduction in polymer usage in solids dewatering.

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.
