Trouble achieving a healthy sludge blanket?

Is there to much inert solids in your sludge preventing compaction?

Do you have to raise your pH when use Alum?

Magnesium Hydroxide as a Coagulant

The further away from the noble gasses an element is on the periodic table the denser the ions of that element become.  This increase in density in turn leads to the ion having a strong ability to draw negative charges towards it.  In the terms of Coagulation this means that an increase in charge density leads to an increase in Coagulation.

As we can seeing the corresponding graphic the Mg2+ ion is between the Na+ ion and the Al3+ ion in charge density.  The other thing observed is that the charge density drastically increases as you move to the right.  Na+ ions tends to have limited coagulation benefit due to it low charge density.  Mg2+ ions tend to have a decent coagulation benefit when present in wastewater.  While Al3+ will have the largest coagulation benefits.

A major issue with Al3+ based coagulants in the wastewater world is that they are typically acidic and as a result depress the pH and consume alkalinity when used.  Magnesium Hydroxide provides an alternative to this depressed pH by simultaneously providing coagulation with an alkalinity boost.

AMALGAM -60 for improving sludge compaction

AMALGAM-60 is a formulation of magnesium hydroxide liquid that provides coagulation benefits to your sludge compaction while providing an alkalinity boost.

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.
