Hi,
I am working on the FGD waste having problems with the precipitation of Boron and Sr.I had conducted the Jar test at the lab with the FGD waste water analysis for B 110ppm ,Sr 3.38ppm I increased the pH to 7.5 with Lime and added 25ppm of Na2S the supernatant concentration of B was 99.5ppm and Sr was 3.26ppm.

Can someone please give a data for the Solubility of B and Sr Versus pH or with respect to Sulphide.

I have attached the jar test report in attachment
Regards,
Nitin
