A circular process that turns toxic wastewater from the chemical fertilizer industry into clean water — while recovering valuable acids from the wastewater – has been developed by environmental scientists at Ben-Gurion University of the Negev.

Phosphoric acid is the main ingredient in agricultural fertilizers, a massive industry worldwide.

“Phosphoric acid production generates a lot of industrial wastewater that cannot be treated efficiently because of its low pH and high precipitation potential,” explained co-lead researcher Oded Nir.
