Application Note: Mixing Magnesium Hydroxide

By Pulsair

In industrial applications Magnesium Hydroxide is used in water treatment (acid neutralization), heavy metals removal, gas stream purification (sulfur dioxide, chloride removal) pulp and paper, sugar and chemical processing.

Magnesium Hydroxide is non-toxic and pound for pound four (4) times more effective than Sodium Hydroxide in lowering the pH of waste water; and, it is far less expensive. But up to now Magnesium Hydroxide has had limited application because it is slurry and tends to settle; and mixing it with conventional mechanical mixing equipment is difficult and expensive. Despite its toxicity and cost Sodium Hydroxide remains the chemical of choice for pH equalization. However, in recent months Pulsair's ‘big bubble' mixing technology has shown to be a very effective and economical solution for mixing Magnesium Hydroxide. Switching from Sodium to Mag Hydroxide is not only possible, but overwhelmingly cost effective.

Pulsair can mix Magnesium Hydroxide in tanks of almost any size, configuration or material of construction. Pulsair can also be installed in new and existing tanks with relative ease when compared to conventional mixing methods. Where conventional mixers may require additional structural supports, baffles, special openings and new power sources depending on the tank size configuration and material of construction, installation of Pulsair in tank components can often be completed in less than a day.
