Imagine being able to purify polluted water without using expensive chemicals and highly technical processes. Israel-based company P2W not only offers such a solution, but has multiple successes stories in Africa to back up its claims, writes Laura Cornish.

Pollution To Water (P2W) is a private company that has emerged in the mining industry with great success over the past few years, based on its technology to treat polluted water effectively and cost efficiently.

The company has installed a few water treatment plants for West Africa’s gold industry since 2009 and is targeting major growth across the entire continent, including South Africa.

With this ambition in mind, it recently announced the formation of a partnership with South Africa-based waste water treatment company Tecroveer.

“We believe so strongly in the P2W technology that Tecroveer has established a new division, Thanda Manzi, which will not only represent P2W in South Africa, but will construct the P2W plants going forward, maintain all P2W’s plants in the country and stand as a fully capable service provider for the P2W technologies,” says Izak Cronje, MD for Thanda Manzi

To mark the new venture officially, the companies hosted clients to see its technology in action – through the establishment of a pilot test facility in South Africa’s gold hub, Randfontein. This successfully demonstrated the technology’s ability to treat sulphates in acid mine drainage water without the need for chemicals, or for the traditional reverse osmosis membrane methodology.

In layman’s terms, the core technologies that drive the P2W solution offerings are based on patented electrolysis and electro-coagulation configurations, and are effective in the reduction of all forms of cyanide, sulphates and heavy metal concentrations from internal water process circuits and from discharge streams entering the environment.

“With the use of a small amount of electricity, we can successfully remove any toxic materials from a water stream to meet discharge requirements,” says Palmach Zeevy, P2W CEO.

The company has also recently started offering the mining community a complete slurry treatment solution that is capable of treating all pollution levels of cyanide, arsenic and dissolved heavy metals that exist inside sludge material, which means a tailings storage facility (TSF) is no longer required. This also has enormous positive impacts on the environment.

With this technology, the liquids are separated from the solids and the pollution existing in the solid is transferred to the water and then treated. As a result, two clean streams are received: a stream of solids and a stream of liquids. Both can be remixed or reused according to need.

P2W process advantages

  • a reduced plant footprint, resulting in less space required
  • substantially reduced operational expenditure, compared to other technologies
  • 100% recovery rate and reduced waste solids
  • less than 1% dry cake
  • environment-friendly
 Successful case studies

 AngloGold Ashanti’s Idupriem gold mine (Ghana)

P2W supplied a mine wastewater treatment system with the capacity of 450 m³/h, operating continuously.

Commissioned in March 2009, the plant is treating cyanide, heavy metals and high turbidity.

AngloGold Ashanti’s Obuasi gold mine (Ghana)

P2W supplied a system with a capacity to treat 250 m³/h, treating heavy metals and arsenic.

It was commissioned in February this year.

Golden Star’s Bogosu gold mine (Ghana)

P2W supplied two identical systems, each with a capacity of 275 m³/h to treat cyanide, heavy metals and sulphates.

It was commissioned in May this year.

AngloGold Ashanti’s Obuasi gold mine (Ghana)

P2W is supplying a 500 m³/h system to treat additional mine wastewater. It will be commissioned in August this year.

Business and financial highlights for tailings discharge treatment

P2W designs, constructs, operates and maintains its plants, and thus:

  • provides a sustainable water treatment method
  • offers cash savings, especially when not constructing a TSF
  • reduces hazardous tailings sludge requiring treatment
  • ensures no toxic seepage into the ground and natural water sources
  • eliminates the need to apply for environmental rights to build a TSF
