    Concerns the purification of water for domestic consumption, and in particular an investigation into the feasibility of automating the control and backwashing of rapid gravity filters. The results obtained to date via the simulator indicated that this was a low cost solution. In addition, other features such as fault detection and handling capabilities proved to be an added bonus and could be very... View full abstract»

    The introduction of tighter drinking water quality standards and economic considerations has focused attention on ways to improve control systems for water treatment, and for the disinfection process in particular. This control problem has, however, proved difficult to tackle with automatic control systems, due to the long contact time between the water and the disinfectant needed to ensure reliab...

    Design and implementation of a low cost flexible production unit for assembly, inspection and other sequential tasks while maintaining an open system architecture is explained. All components of the cell are connected to the production unit controller, a PLC, via the installation bus controller area network (CAN). The design is flexible to accept a number of sensors with different functionality su... View full abstract»

    Since 1970, Lyonnaise des Eaux has developed a policy of automation at its water treatment plants. Originally based on solid logic modules, the technology used was upgraded and improved in the late seventies by the progressive and extensive use of programmable logical controllers (PLC). Since 2nd of May 1984, the potable water production of the western suburb of Paris (1 million inhabitants) has b... View full abstract»

    This paper reviews the experiences of Bechtel Water Technology in the application of programmable logic controllers. The paper outlines how experience of industrial disputes followed by the introduction of EC Drinking Water Directives during the 1980's generated a requirement to build a substantial number of unmanned automated plants. This resulted in a substantial increase in the number and sophi... View full abstract»
