WPL has been awarded a contract for permanent replacement of a rotating biological contactor (RBC) at United Utilities Mowpen Brow wastewater treatment works near Knutsford, Cheshire.
WPL’s Hybrid-SAFTM enhanced biological treatment process will be retrofitted into the existing RBC tank at the site.
The precision-engineered submerged moving-bed, fixed-film technology was developed in-house by WPL and can be retrofitted into any vessel, regardless of shape or size. WPL’s team worked closely with United Utilities to identify the most effective and cost-efficient solution for the Mowpen Brow works once it was decided to replace the RBC.
The installation will increase total capacity at Mowpen Brow, which serves approximately 300 population equivalent. It will also deliver highly efficient wastewater processing, meeting the descriptive environmental consent.
By repurposing existing onsite infrastructure, rather than ripping-out and reinstalling the tank, the utility will make significant cost-savings and reduce environmental impact.
Andrew Baird, technical director, WPL said:
“WPL has worked in partnership with United Utilities for over 20 years and we’re delighted with this latest contract win.
“The modular nature of the WPL Hybrid-SAF means the technology is highly adaptable to existing vessels of different shapes and sizes. At a restricted site like Mowpen Brow, it may be one of few options available.”
