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.

EXISTING TREATMENT METHOD: LIME DOSING
 

  • 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.

EXISTING TREATMENT METHOD: LIME DOSING
 

  • Zinc mine and processing facility in care & maintenance

  • Tailings dam (cause of AMD) full and requires emptying before site can be re-used
     

BioAqua R&D plant has successfully operated on both sites demonstrating capability to clean water.

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.
