Hi,
Have you tried Lime? Probably you will need to add permanganate to oxidize forst and then lime sln. The result is gypsum that precipitates.
Barium may work as well but that is too expensive. Barite precipitates more than gypsum. Magnesium-hodroxide solution may work as well.
OMYA has products to use.

Thank you Zsolt ! It's a good idea !
No, I didn't try with Lime. I Always have some problems with Lime, because it's necessary to correct the pH after that and not to mention the huge amount of sludge that it's generated.
