Many metal treatment processes produce acidic waste streams, which have to be neutralised before discharge, to meet pH and metal consents. Traditionally caustic soda and lime have been used, but these materials are difficult and dangerous to handle, and often create other environmental problems.
The viability of using magnesium hydroxide as a safe, cost-effective alternative alkali has now been recognised, and Omex have introduced a stable, easy-to-use suspension, Magmex 706, which is now being used for pH correction and metal precipitation in a wide range of effluent treatment applications.
