Selenium removal from wastewater is an issue that many industrial operations aiming to meet discharge regulations must address. While selenium is a naturally occurring element, certain industrial activities can elevate its concentration in waste and process water. Activities such as mining, refining, coal combustion, and processes that concentrate a water stream, such as reverse osmosis, can increase selenium levels. These increased levels pose potential risks to both aquatic ecosystems and human health. To address these risks, federal and state regulatory agencies have implemented effluent limits for selenium across these industries, as a result, treatment is often required before discharge.
Ground and surface waters may also need to be treated for selenium if used as drinking water sources or if removal is required ahead of the downstream process.
