ITRC Publishes New Web Based Guidance Document on Biochemical Reactors for Mining Influenced Water

A new ITRC web-based guidance document describes how biochemical reactors work, the contaminants treated, various designs, monitoring and maintenance requirements and schedules, and troubleshooting. Biochemical reactors are land-based engineered treatment systems that use an organic substrate to drive microbial and chemical reactions that reduce concentrations of metals, acidity, and sulfate in mining-influenced water. Fifteen case studies present real-world examples and include details such as volumes of water treated, substrates used, pH and metals concentrations, and biochemical reactor size. This new ITRC guidance document can be accessed at www.itrcweb.org/bcr-1. ITRC also offers a free corresponding Internet-based training course on biochemical reactors. See www.itrcweb.org/Training for more information and schedules for ITRC's Training Program.
