“Power and Water employees have gone the extra mile with delivery and innovation to support our ambitious programme, which aspires to provide treatment of polluting metal mine water discharges and generate better river water quality with richer and more diverse ecology. Preliminary results are very encouraging, and we are excited at the prospect of adding this Sono-electrochemical method as another tool. Its spatial footprint is small and therefore particularly suitable to rugged upland locations where large passive pond systems require flatter land that is often in short supply.
