Full scale pilot test of a novel technology to remediate alkaline coal mine water using high-surface media at Acomb Mine Water Treatment Scheme, UK

摘要

Acomb scheme is an existing coal mine water treatment scheme, which recently has been struggling to treat the iron-rich water. This scheme, like the majority in the UK, uses conventional methods of aeration cascades, settlement lagoons and aerobic wetlands. At Acomb, a full-scale pilot test of a Deferum treatment unit was installed, which uses high-surface media to remove the iron. This unit at Acomb successfully removed an average of 74 % of the iron from the mine water. Going forward, this type of treatment is likely to be useful where there are difficulties due to restrictions on land and costs.
