“Rio Tinto has worked with Virotec since the early 2000’s and most recently over the last two and a half
years directly with Rio Tinto Aluminium Bauxite and Alumina Pacific Operations (RTA) to understand and
evaluate the potential capacity of its Bauxsol Technology to treat red mud produced by Rio Tinto’s
Gladstone alumina refineries. This has led to a Stage 1 processing facility located at the Queensland
Alumina Refinery (QAL) in Gladstone. With this facility in place RTA are working with Virotec to increase
the volume of material created and used for beneficial reuse in a variety of remediation and other uses.”

“Virotec’s solution was to treat the water so that the mercury formed in an inert sludge layer at the tank bottom. Concrete was then poured onto this sludge layer to encapsulate it with the water discharged to the environment at well below discharge limits. Holes were then drilled into the tank base so that when it rains, the tank does not fill up.

For 10 years we had wrestled with this problem but Virotec’s unique thinking and technology that works made it happen. And all at a price that we could afford. They are the “go to” guys. ”

“Our Wesley Vale paper mill had accumulated about 80 tonnes of mercury contaminated water in a storage vessel that was corroding badly, with a risk to human and aquatic life. We could not find any economically viable method to treat and release the contaminated water…”

“Virotec put our project back on its’ time track at a lower than expected cost. They also treated components that cause significant health issues which cannot be remediated by traditional methods. All the boxes were ticked and we are very happy. “

“Virotec optimised the performance of our wastewater treatment process including reagents, technical support and liaison with regulatory authorities.

Our wish list was exceeded and our trade waste discharge is well below EPA limits. There are better than expected cost savings for factory process flows. These guys know their stuff. “

“ We are a well known Australian large-scale copper, chrome, and arsenate (CCA) treatment plant. Our leachate ponds had CCA contaminated water and we were not complying with our discharge limits. We had no one to turn to but we knew that Virotec had successfully treated cyanide contaminated water in Romania which also contained arsenic.
After successful testing, Virotec treated our leachate ponds and the CCA metal levels dramatically reduced to well below our licence limits – we would not be shut down!

Virotec are unusual in that they will work with you, no matter how hard the environmental problem is, to solve your issues, improve your current practices and save you money. “
