Festo has supplied actuators for the control of process gates in the Les Grésillions water treatment plant. The plant purifies over 100 000 cubic metres of sewage water for the greater Paris region and returns it to the Seine river system every day. Les Grésillions makes use of advanced screening and filtration systems as well as bio-filters and Biolest technologies to remove the nitrogen and sewerage content.
Festo developed a special Copac linear actuator DLP with through piston rod for the 28 Fontaine shut-off valves in the bio-filters as well as the valves controlling the backwashing process. The actuators have been designed without housing to facilitate the fitment, and use of a hand wheel, which can be used in the event of an emergency. Each shut-off valve is equipped with two proximity sensors SME-8 for sensing the mechanical stops and transmitting them to the controller.
CPX is the name given to the Festo modular electrical terminal online diagnostics system which allows for the connection of pneumatic and electrical control chains to automation systems. In the Les Grésillions plant 28 de-centrally installed electrical terminals, in conjunction with the valve terminal MPA actuate the drives and record all the data relating to the 28 filtration tanks. Each tank has an interface with the centralised Allen Bradley controller via a DeviceNet fieldbus that is connected to the valve terminals. The CPX also integrates the front-end controller FEC for managing the control circuits locally and ensuring safety positions. Its diagnostic functionality enables the CPX to quickly detect any faults in the plant. The IP67 protection allowed the open installation of the electrical wiring and the pneumatic tubing without a protective guard. Installation costs were kept to a minimum as a result of the high protection class and the CPX system.
Festo is also responsible for the training of staff in the use of its products, as well as the commissioning of the equipment supplied. Festo will continue to work with the Les Grésillons as a further 70 filtration systems are to be installed by 2012.
