NOV® MONO® PROVIDES COMPACT SOLUTION FOR FAIRBOURNE WWTW

Two of NOV Mono’s revolutionary EZstripTM progressing cavity (PC) pumps have been installed at United Utilities Fairbourne wastewater treatment works in Wales to improve process efficiency by reducing downtime on a critical site process.

Fairbourne WwTW was constructed in 2003 and treats flows from Fairbourne and Bryn Coch pumping stations. Flows to the works pass through a two stage screening process into an anoxic zone and then into a submerged membrane bioreactor (MBR) plant comprising MBR cells. Final effluent from each MBR cell is pumped out to sea through the Fairbourne outfall.

The two Mono EZstripTM maintain in place (MIP) pumps have been installed to pump return activated sludge (RAS) from one MBR cell to another at 55m3/h. Due the critical nature of the process, the pumps are required to operate continuously and an additional EZstrip pump has been supplied as a spare to United Utilities Operational Services, the site operator.

Mary Alexander, Senior Mechanical Engineer at Imtech Process, the project contractor, commented: “We specified the Mono EZstripTM pumps because as well as offering a massive reduction in downtime for maintenance and repair, they eliminate the requirement for stator dismantling space, allowing the installation to be kept compact. 

The Mono pumps are reliable and have been operating smoothly since their installation. We are very happy with their performance.”
