We have a 10,000 gal. acid cleaning tank. We use it to de-smutt aluminum parts that have been chemically milled. The tank is old and not working very well. Although a tank rebuild is not out of the question I was wondering if there was some economical process, say plating for instance, that would remove some or all of the dissolved crud that is in solution? The acids in the tank are nitric @ 23 oz/gal. and about 15 gal of hydrofluoric. There are some metals from the aloys of the aluminum and residue from the caustic chem mill tank.
Thank you
fix the tank cheap
