WATER BY NUMBERS
Until recently contaminated mine water was waste water, but in South Africa such waste is simply no longer tolerable, and a technology exists that can turn this wasted mine water into drinking water. Removing salt, dirt and acidity from contaminated water requires a scientific process called reverse osmosis. First observed in a laboratory in the 1950s it was only the 1970s that reverse osmosis was used to create potable water on an industrial scale. The process removes all kinds of contaminants, including bacteria
Call it H2O, Dihydrogen Monoxide or Hydroxic Acid. Consider it two hydrogen molecules bonded with an oxygen molecule if you like. We just call it water and, with a bit of effort, we think we’ve shown that a better future is possible.
In 2017, the theme is wastewater and the campaign, is about reducing and reusing wastewater. Globally over 80% of the wastewater generated by society flows back into the ecosystem without being treated or reused – polluting our environment. Safely managed wastewater is an affordable and sustainable source of water, energy, nutrients and other recoverable materials.
