Rotork IQ intelligent electric valve actuators are installed throughout the advanced new Reading Sewage Treatment Works, UK. Approximately 150 Rotork actuators control the movement of flows throughout the site, from the fully enclosed inlet works to the tertiary
filters from where the treated wastewater is returned to the local watercourse in line with the latest EU and Environment Agency standards. Data loggers in the actuators store historical operating data and valve torque profiles, information can then be downloaded and analysed
using Rotork IQ-Insight software. The collected data can help to optimise plant performance by identifying potential problems and facilitating predictive maintenance. An equally advanced control system has been installed, using twenty-three Profibus 2-wire segments for the instrumentation, actuators and package plant, which are linked to several latest generation PLCs situated throughout the site.
