Fang Chemicals

Spent Phosphoric Acid

At Fang Chemicals Inc., we are a global chemical company successfully servicing the entire phosphoric acid industry by distributing and marketing phosphoric acid, phosphorous acid, and other phosphorous chemicals.

Spent phosphoric acid 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 waste water treatment and fertilizer production.

Fang Chemicals offers two types of spent phosphoric acids: P35 and PS40. To learn more our spent phosphoric acid solutions, contact us or see the table below.
