Abstract
A method of reducing the concentration of dissolved selenium in water includes introducing water having solid selenium-containing particles and a metal that bonds with selenium into a vessel and precipitating a metal-selenium compound from the water. A method of reducing the concentration of dissolved selenium or reducing dissolution of dissolved selenium, including providing a source of electrons into the water to precipitate dissolved selenium compounds is also disclosed. The precipitated compounds are separated from the water to produce decontaminated water. A system for reducing the concentration of dissolved selenium or reducing dissolution of dissolved selenium is also disclosed. The system includes a vessel fluidly connectable to a water source, at least one solid metal source, and a source of electrical voltage electrically connectable to the metal source.
