Minimum operator intervention at Mourne WTW

The supply and installation of 100 AUMA actuators utilising Profibus DP version 1 technology to Mourne Treatment Works in Northern Ireland supports a move toward minimum operator intervention at the plant. As one of the water sector’s first applications for the new generation fieldbus solution, the installation represents a landmark contract for AUMA. The GBP 20 million WTW, which is Northern Ireland’s largest greenfield water treatment works, treats up to 155MLD of water from the Silent Valley reservoir in the Mourne Mountains. Supporting 280,000 people in the North Down and Greater Belfast areas, the site comprises flocculation, dual media filtration and chemical treatment. Controls for the treatments works revolve around a Siemens PLC system and a Profibus DP communications network connecting intelligent motor control centres, actuators and instrumentation.
