How to remove excess iron in PAA tank
How to remove excess iron in PAA tank
(OP)
Howdy all,
Over the weekend we had a heater line burst in our phosphoric acid anodize (PAA) tank which dumped iron rich water from our hot water system into our PAA tank. Is anyone familiar with a method to remove the iron so we can avoid recharging the tank from scratch? Any suggestions pointing me to more information is welcome. I think this may be more appropriate for one of the chemical engineering/chemistry forums, but since this process is for aircraft structures (BAC5555) I thought I should throw it out here first. the tank has phosphoric acid with sodium dichromate.
Thanks,
-Kirby

Try talking to these people

They make resin beads for removing contamination from acid tanks.
