The outcome of a new study on desalination breakthrough that could lead to cheaper water filtration is of immense relevance to countries including Qatar, dependent on desalination of seawater for their growing water needs.

Producing clean water at a lower cost could be on the horizon after researchers from The University of Texas at Austin and Penn State in the US solved a complex problem that has baffled scientists for decades, according to an article in journal Science.

Desalination membranes remove salt and other chemicals from water, cleaning billions of gallons for agriculture, energy production and drinking.
