Source of Selenium: Selenium is a natural mineral found in the earth’s crust. Selenium also comes from natural run-off, industrial wastewater from copper and lead refineries, municipal wastewater and leaching from hazardous waste disposal sites. Mining operations can contaminate surface and groundwater with selenium.
Health Effects of Selenium: Being exposed to high levels of selenium for a long time (in drinking water) can cause hair loss, brittle nails, and neurological problems.
How to Remove Selenium: A WECO activated alumina backwashing filter will remove selenium from all the water entering the home or commercial facility. WECO also offers a point of entry (POE) filter using anion-exchange resin in the chloride for. The system is regenerated using sodium or potassium chloride. For residential drinking water purification, a WECO reverse osmosis system is recommended. We recommend consulting with a WECO technical support specialist to determine which filtration system is right for your application.
