BN Aqua has built and commissioned a prototype based at the Council for Scientific and Industrial Research (CSIR) to treat the acidic water from the gold and coal mines to potable stage which is suitable for human consumption.
The prototype can treat 20 000 litres per day of contaminated water to drinking water. This was also confirmed by the obtained laboratory water quality results, which positively exceeded the SANS 241 drinking water standards. The project is supported by the University of Johannesburg Technology Transfer Office, which holds the Intellectual Property for the invention and licensed it to the inventor.
The prototype uses a metallurgical waste product to treat this acidic water and this innovative solution is our unique selling point. This innovative process will lead towards pollution remediation of the waste material and recover saleable minerals such as gypsum, magnetite and synthesized lime while increasing South Africa’s
drinking water capacity
