Water treatment, removing boron [India]  

++++

Waste water contains boron of 300 ppm should be removed effectively to less than 5 ppm. Would like to get suggestions.

Your solution is by oxidizing with Electrolytic Catalytic Precipitation (ECP) removing method. In this method we will oxidize the metals by overdosing the wastewater with oxygen and electrolytic breaking of the molecules. The results are solid metal oxides and gases and water.

What is the formula for that oxide of boron that you will be forming, Mr. Dinu? Is it B₂O₃? I was under the impression that this oxide dissolves in water, forming boric acid. What oxide of boron will efficiently precipitate? Thanks.
