P2W specializes in the chemical-free method of water treatment in gold mines, following the separation process of heavy metals, cyanide and arsenic.

The South African AngloGold Ashanti company, a publicly traded company and – with 17 gold mines – the third largest gold miner in the world, has contracted P2W to build and operate water treatment plants. P2W’s system treats 500 cubic meters of contaminated water per hour and will provide employment to the area.
P2W develops, markets and installs water purification systems for toxic heavy metals, precisely because of the huge amount of such metals – including arsenic, copper, zinc, cadmium, lead, nickel, titanium, manganese, tin, cobalt, etc. – that finds its way into the water supply during the mining and production of gold. These polluted water cause immense damage to the environment.
The unique process developed by P2W is based on combined electro-coagulation and electro-oxidation, using a minimal amount of chemicals. It allows streaming the treated water into the sewage or recycling it. The system promises a return on investment within 16-36 months. At present, the infrastructure and technology is being successfully implemented in Ghana and other developing countries.
CEO Palmach Zeevi, who founded the company in 2005, says. “The signing of this latest deal proves that the technology developed by our company is the correct solution for companies engaged in gold mining around the world.”
According to Zeevi, South Africa presently faces a particularly challenging task. For decades, gold mines have been contaminating the groundwater in the country’s three main water reservoirs. It is known in South Africa as AMD (Acid Mine Drainage), and the topic has dominated the media’s agenda for the last two years. “We, ” says Zeevi, “that is, my wife Susan, our staff chemists, engineers and I, took it upon ourselves to go there with a ready solution., Six months ago, we established a pilot program; and after two months, results prove that we have managed to introduce technology that can deal with the difficult problem.” Today the company has six operating systems, to which seven more will be added in the coming year. Another first pilot is planned for Latin America this year (2013).
