BIOAQUA TECHNOLOGY
BIOAQUA PROCESS
TWO STAGE PATENTED PROCESS
STAGE 1: METAL SEPARATION
Removes metals and acidity from contaminated water.
STAGE 2: SULPHIDE REDUCTION
Involves the bacterial treatment of the water to remove the remaining sulphates and calcium contaminants.

From SA Govt. Project Director Report- 2016:
“While the concentration of contaminants in the water are managed by interception and treatment, this is not a permanent solution. Treatment would be required for 700-1000 years.” -
Since 2007 an expert Technical Advisory Group has overseen extensive testing to develop a remediation strategy. Their conclusion is to “cap” the AMD source.

Zinc mine and processing facility in care & maintenance
-
Tailings dam (cause of AMD) full and requires emptying before site can be re-used

BRUKUNGA RESULTS
Global Aquatica test results from our R&D plant located at Brukunga, a Government owned mine site in SA. After application of BioAqua, independent NATA accredited confirmed the treated water test results tabled above.
NATA TESTED
THE NEW STANDARD
Existing practices are typically only based around containment of the problem, and potentially some limited form of treatment. BioAqua sets a new standard in erradicating AMD through the use of our two stage process.
