Spent sulfuric acid available free

Q. Have excess sulfuric acid from acid recovery unit from an anodizing line. Would make excellent waste treatment additive, and we would be willing to give the solution free to someone who could use it. We can provide analysis of solution upon request.

A. This sounds like a good application to me. The aluminum ought to be helpful in mechanical settling, and the sulfuric acid is less dangerous to work with than concentrated sulfuric. Which demands the question: why can't you use it for waste treatment yourself?

A. It seems anodizers always have an excess of acid, particularly sulfuric with dissolved aluminum. It would be nice if we could match up with someone with the opposite problem. However, wouldn't some hazardous waste regulation prevent this kind of exchange. i.e.,storing,transporting,etc. It only makes too much sense

Q. We do use it in our waste treatment system, but our processes generate more than what we can utilize. Also, if the solution is good waste treatment chemicals it can be shipped like any normal solution you buy from your industrial chemical supplier i.e sulfuric acid. There are a lot of non-anodizer facilities that would make a good match thats what I am trying to accomplish, and yes you are right, it does make too much sense, it would be a win-win situation for the anodizer and the final end-user recycling this product for good use.
