Recycling used powder coating stripper (Sulphuric acid)
We are stripping powder coatings on aluminium sections in sulphuric acid and have no problem except when it comes to treatment before throwing it into the drain. The amount of sludge it creates is mind boggling.
How can I recycle this sulphuric acid or please suggest any other solution to depaint.
