Wastewater odour control systems in Tasmania

Audrey Barucchi \ March 15, 2020

TasWater engaged with Netco Pumps to explore different options and after speaking with a lot of industry contacts Netco ran a trial at the treatment plant of ACTI-Mag product by Calix. This immediately proved successful as the product had a much finer molecular structure and was more viscous, overall it proved much easier to pump and handle as well as having a good reactivity time.

ACTI-Mag is a concentrated stabilised suspension of magnesium hydroxide, an inorganic compound with the chemical formula Mg(OH)2, the method by which Calix calcinates the raw product results in a product with a much higher surface area which has multiple benefits.

Calix recognises that Safety, Health and Environment (SHE) management must be integrated into all operations in our organisation. In light of the latest advice on corona virus, and the need to work more remotely, Calix has created a series of webinars so you can take advantage of Calix’s know-how without leaving your home or office!

The value of magnesium hydroxide as a substitute for #caustic soda in #wastewater treatment

Unlike #caustic, ACTI-Mag is non-hazardous % non-corrosive
=> this means further $$ savings
