Rotork Actuators Support Portugalís Plan for Advanced Wastewater Treatment

The Viseu Sul WWTP in Portugalís Viseu County is the first in the country to adopt advanced membrane filtration (MBR) wastewater treatment technology.

Profibus DP-enabled Rotork IQ intelligent non-intrusive valve actuators support Portugalís plan for advanced wastewater treatment.

Profibus DP-enabled Rotork IQ intelligent non-intrusive valve actuators support Portugalís plan for advanced wastewater treatment.

The highly automated treatment facility, serving a population of 90,000, was recently inaugurated by the President of Portugal, Marcelo Rebelo de Sousa, and is named as a national environmental benchmark for future developments.

MBR treatment plants work without the addition of chemicals and with relatively low energy consumption, combining secondary and tertiary treatment and eliminating traditional sand and carbon filtration. Centralised process control and automation at Viseu Sul is facilitated using Profibus DP network technology, utilising Rotorkís latest multi-turn and part-turn intelligent non-intrusive electric actuators (IQ and IQT respectively) to operate penstocks and butterfly valves for flow control throughout the wastewater treatment process.

The Rotork IQ Profibus DP interface card provides comprehensive control and feedback data about the valve and actuator using DP-VO cyclic communication. Extensive actuator diagnostics and configuration information is included in the DP-V1 acyclic data supported by the card, enabling valve profiling and diagnostic data collected by the IQ actuator to be incorporated into asset management systems.

The Rotork reputation for all-weather reliability in the global water and wastewater treatment industries, combined with the local availability of technical support from the manufacturer available from Rotork Iberia, also made important contributions to the selection of IQ actuation technology for this landmark project. In addition to being the most advanced WWTP in Portugal, the new Viseu Sul plant will enable the closure of other treatment plants in the area which do not meet the latest environmental regulations.
