Rotork IQ actuators have been installed at a Brazilian water treatment plant.

The majority of the 136 IQ electric actuators control the inlet, outlet and backwashing functions on the new and existing filters. The remainder of the actuators were installed on the sludge collectors, sludge thickeners and secondary collectors from which the raw water is extracted for treatment.

The water treatment plant upgrade involved building an additional filter plant, replacing obsolete actuators on existing plant and introducing a Profibus digital control network.
