Sunlight to solve the world’s clean water crisis

Researchers at UniSA have developed a cost-effective technique that could deliver safe drinking water to millions of vulnerable people using cheap, sustainable materials and sunlight.

Less than 3 per cent of the world’s water is fresh, and due to the pressures of climate change, pollution, and shifting population patterns, in many areas this already scarce resource is becoming scarcer.

Currently, 1.42 billion people – including 450 million children – live in areas of high, or extremely high, water vulnerability, and that figure is expected to grow in coming decades.

Researchers at UniSA’s Future Industries Institute have developed a promising new process that could eliminate water stress for millions of people, including those living in many of the planet’s most vulnerable and disadvantaged communities.

A team led by Associate Professor Haolan Xu has refined a technique to derive freshwater from seawater, brackish water, or contaminated water, through highly efficient solar evaporation, delivering enough daily fresh drinking water for a family of four from just one square metre of source water.
