Nanotechnology Brings Clean Water to Rural Pool

The sustainability problem: Water Sustainability.

One of the modern technologies that can help in the addressing of water sustainability problem is nanotechnology. According to a report by the World Health Organizations over 1.6 million people die each year due to lack of clean and safe drinking water. The nanotechnology removes microbes, bacteria, and other matter from water meant for human use particularly drinking by use of composite nanoparticles that emit silver ions which destroy the water contaminants. An interesting thing is that this technology is highly scalable in terms of cost, with the cost of getting purified water by this technology going for as low as only $2.5.

  • Water filter composed of a grainy mix of nanoparticles
  • Composite nanomaterials
  •  Nanoparticles oxidized
    • Release a continuous stream of silver ions – kill bacteria
  • Other composite materials remove arsenic, pesticides, lead and other heavy metals from the water

  • Governments
  • Communities – especially those communities in rural areas
  • NGOs
  • Material manufacturers
  • Utility companies

Deployment:

  • Educate people in the rural area about safe drinking water.
  • Partner with NGOs and governments to reach communities

Clean drinking water is a big challenge for many people across the globe. Despite there being many efforts to invent technologies that can help achieve clean drinking water, another challenge of energy needed to run some of these purification equipment sets in. A new technology currently being used in the California is a solar-powered pipe that can generate its own power and use this power to process water for drinking. It is a technology that if properly developed can go a long way toward contributing water sustainability on a global scale.

  • The solar-powered plant deploys electromagnetic desalination to provide clean drinking water.
  • The system also contains a system with a mechanism that allows for filtration of the desalinated brine through onboard thermal baths before the brine can be reintroduced into the ocean.
  • The system has solar panels that provide power to pump seawater through an electromagnetic filtration process.
  • The technology leads to the design of equipment that can generate 10,000 MWh per year, the power that will then be used to produce 4.5 billion liters or 1.5 billion gallons of pure and safe drinking water. For most drought-prone regions, the Pipe represents a change in the future of drinking water as it saves energy by generating its own solar power than requiring external sources of power.
