Top Neutralizer Of Acidic Wastewater: Aries 100 Mg(OH)2
Top Neutralizer Of Acidic Wastewater: Aries 100 Mg(OH)2

Calcium sulfate, is an insoluble compound formed when lime neutralizes sulfuric acid and greatly increases sludge volumes generated in wastewater treatment. The theoretical amounts of Aries 100 magnesium hydroxide needed to neutralize sulfuric acid and hydrochloric acids are compared to various alkalis on the chart following this discussion.
