Water treatment plant boosted by actuators for ultrafiltration processes

19 October 2021

A water treatment plant in Texas has ordered hundreds of Rotork’s K-TORK rotary vane actuators for use in its ultrafiltration system.

San Felipe Springs Water Treatment Plant is supplied by water from the nearby East and West San Felipe Springs and uses an ultrafiltration system to process the water. The centre has an incoming flow of 18.2 million gallons per day. The treated water serves the population of Del Rio and the nearby Laughlin Air Force Base. 

The primary process used is ultrafiltration, which removes unwanted particles from the water. Membrane systems such as this provide treated water that has been pushed through a thin membrane that removes solids and contaminants, resulting in water suitable for drinking.

Nearly 400 K-TORK rotary vane actuators were ordered for the plant to aid in the ultrafiltration process. These accurate and reliable units have replaced existing actuators to ensure reduced maintenance and replacement costs. They are suited to use in critical applications because of their high cycle and precise modulating output. They do not need to convert linear motion to rotary motion, which means they offer true rotary control. A direct drive design means K-TORKs provide accurate modulating specifications. The client chose Rotork and K-TORK actuators because of the benefits of reduced maintenance and lower replacement costs compared to their previous units, as well as the reliability of its products and support that Rotork can offer. The majority of the actuators have now been installed.
