The Royal Mint is reporting success with its new effluent treatment plant and supporting instrumentation, which are enabling the Llanstrisant, South Wales, plant to discharge 100% effluent into the sewer, without damaging the infrastructure or the environment.
The new multi-million pound effluent treatment plant replaced two treatment lines and now supports increased production capacity from two new nickel plating lines.
Graham Hartry, environmental manager, Blank Processing at The Royal Mint, explains that, for sewer discharge to be allowed, the plant had to be equipped to monitor hydrogen peroxide, pH and turbidity to ensure the safety of the effluent.
"Our new effluent treatment plant has been built using the best available technology [BAT] and will significantly reduce the amount of effluent discharged, allowing us to recycle wherever possible," states Hartry.
"The use of Analytical Technology's pH, hydrogen peroxide and turbidity monitors has allowed us to regulate the levels of chemicals and suspended solids within our effluent discharge, ensuring that we comply with stringent regulations and do our utmost to protect the environment."
