Meeting changing discharge requirements starts with understanding what works under real mine-site conditions. In this video, Brown and Caldwell’s Meggy Gidula, Mining Market Sector Leader, joins Dominic Pontarolo, Industrial Water Area Practice Leader, to discuss a pilot study pairing a moving bed biofilm reactor (MBBR) with ultrafiltration at a remote metallurgical coal mine in the Pacific Northwest. The system reduced selenium and nitrate below the mine’s discharge limits while providing practical operating data to inform full-scale design. 

Watch the full conversation to explore practical considerations for pilot testing, treatment performance, and planning a reliable full-scale mine water treatment system.
