ACCURATE POSITIONAL PERFORMANCE
23 October 2012
Rotork’s CVA electric control valve actuation technology has been selected for a demanding duty involving continuous modulation at what is described as a ‘new generation’ waste water treatment plant in southwest France.
Significant biogas production at the plant generates the daily equivalent of 27,000kWh.
The biogas is produced in a process which uses a combination of solids filtration and biological aeration to remove pollutants including ammonia. The Rotork CVA actuators are installed on butterfly valves to regulate the continuous supply of air to the process. Accurate air regulation enables the plant to run efficiently and reduces air wastage.
On previous installations pneumatic actuation was used for this application, but the more accurate positional performance available with the CVA has enabled the adoption of the electrical solution on this site.
