Arsenic Removal
The first method is called Arsenic Removal Using Bottom Ash (ARUBA). Bottom ash, a widely available waste material from coal-fired power plants, is coated with iron rust, which binds to arsenic. The arsenic can then be removed from the water through settling and/or filtration. The second method is called ElectroChemical Arsenic Remediation (ECAR).Web
