Power & Water, commissioned by Natural Resources Wales (NRW) at Cwm Rheidol mine, proved the innovative and patented Soneco (Sono-electrochemical) technology for effective treatment of Acid Mine Drainage (AMD).
The technology was trialled at one of the UK's top 5 most-polluting abandoned metal mines; with very high metal concentrations in the discharge water entering the River Rheidol.
Power & Water successfully removed up to 99.5% of Zinc, Lead, Iron and Cadmium whilst simultaneously reducing other metal concentrations with high reduction rates.
P&W and NRW are now working on the full scale-up and installation enabling the clean-up of such metal mines - keeping our rivers and aquatic life safe and
healthy.
