INDUSTRIAL CASE STUDY Project Scope A Northeast Acid Mine Drainage (AMD) treatment facility was using calcium hydroxide (lime) to precipitate iron from the mine pool water. The iron in the water stream is in soluble form known as ferrous iron (Fe 2 ). Lime was used to raise the pH of the water from 6.2 s.u. to over 8.0 s.u. to precipitate out ferrous hydroxide (Fe(OH) 2 ). USP Technologies (USP) was selected as the Hydrogen Peroxide program pro
