SIPOS actuation addresses Australian WwTW water hammer

April 13, 2012 - PRLog -- The established manufacturer and global supplier of actuators provided a sophisticated valve control solution for a remote supply line – the work supported an upgrade initiative for Lower Molonglo, the sewerage and waste water treatment facility for the Australian capital of Canberra.

Owned and operated by the ACTEW Corporation, the scheme is Australia’s largest inland treatment facility which processes more than 90 million litres of Canberra’s wastewater daily. Meeting a design challenge to provide greater valve control, SIPOS installed split mounted actuation technology at a supply site some 16 miles South East of the treatment works.  

SIPOS’ local agent Barron GJM secured the contract and provided local support to commission the actuation solution. Commenting, Weyand Magnaye, Water Products Manager for Barron said:

“The variable speed capability of SIPOS’ actuation technology which addresses water surge was a key reason for its selection for this scheme – adjustable positioning generates a linear flow, this enables fine-tuning of operating speeds and prevents water hammer.

“A key challenge was replacing existing actuation with process control technology that provided a high degree of flexibility and ‘future proofed’ the solution with additional control steps. Specific operating times and simplified set up achieved by direct inputs ensured the requirements were met and a high degree of control flexibility was provided.

“A split mounted solution from SIPOS ensured that setting and control of the valve was made easy for operators – to achieve this, the electronic control unit was installed above ground and the motor gear unit was located underground with the valve and pipework.”

The SIPOS 5 Flash actuator is set apart from other actuation technology with its capability to control valve position based on pre-set time intervals. Up to ten time set points, with corresponding valve positions, can be programmed which addresses water hammer. A growing portfolio of SIPOS Aktorik water sector contracts secured by Barron include Sydney Water STP, Australia’s fourth largest sewage treatment plant.
