Polishing solution co-product is a by-product generated from the chemical polishing of aluminum, also known as a Bright Dip operation. The acid typically contains a mixture of phosphoric acid, sulfuric acid, nitric acid, and also contains a small amount of dissolved aluminum with no detectable suspended solid. This by-product is not waste and actually has uses in biological wastewater treatment and fertilizer production.
