Magmex Range

A range of Magnesium Hydroxide suspensions for treating acidic wastewaters and controlling pH levels within both anaerobic and aerobic systems.

Traditionally, sodium hydroxide (caustic soda) and calcium hydroxide (lime) have been used to neutralise acidic solutions. However, these compounds are reactive and can cause high pH levels if not controlled correctly.

The Magmex range is the environmentally friendly answer to the neutralisation of acidic wastewater. It is safe, ready-to-use and overcomes the majority of problems associated with the traditional acid neutralisers such as caustic soda or lime.

The Magmex range includes;

Magmex 1060

A unique formulation specifically designed for use in situations where higher pH levels are needed to enhance precipitation.

Magmex 740 

A standard formulation for use where a safe, efficient alkali is required for pH correction and where minimal sludge volumes are needed.

Magmex 706

A stable formulation for use in smaller scale applications where longer term storage is required without the need for agitation.

Magmex OP Series

OMEXs exclusive range of magnesium oxide and hydroxide powder products, which are available for a wide range of applications.


Completing the range of neutralisers, Calmex is a high concentration Lime suspension.
