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.
Fang Chemicals offers two types of Polishing solution co-product: P35 and PS45. To learn more our spent phosphoric acid solutions, contact us or see the table below.
