The Environmental Impact Of Anodizing
The Environmental Impact Of Anodizing

The collected aluminum hydroxide is sludge, and the acid bath is then cleaned of it. In another process called acid sorption, the exact opposite takes place. In acid sorption, ion exchange resins absorb the sulfuric acid while the metals pass by. The resins then release the acids in a water wash, and the metals are collected for disposal.
