A research team of environmental scientists from Ben-Gurion University of the Negev has developed a process to eliminate the risk of phosphoric acid plant wastewater. The wastewater is turned into clean water. Industrialfertilizer is the main ingredient in the world.
The method was published in the journal. The research was led by LiorMonat, a PhD student.
A lot of industrial wastewater can't be treated because of its low pH and high precipitation potential.
The water is usually stored in ponds. These are prone to leaks and floods. There was an ecological disaster in Israel a few years ago when millions of liters of acidic wastewater were flushed down a creek. Conventional treatment processes are difficult to deal with.
An alternative three-step process for the treatment of phosphoric acid wastewater was developed.
The method was evaluated with positive results. The process was able to reduce the volume of wastewater. It didn't produce any mineral scaling, which could cause problems.
It would appear that the method would be sustainable and economically viable because of the low power requirement.
Dr. Roy Bernstein, co-lead researcher, says that the process is very promising and encourages industry players to examine its potential and applicability at their factories.
