About Nereda® at Failsworth wastewater treatment works in UK

Failsworth is a town in Greater Manchester, England, which is 6 km northeast of Manchester and 4.7 km southwest of Oldham.

THE CHALLENGE

To meet the required improvement in the water quality of the River Medlock, United Utilities has developed the Medlock Quality Improvement Programme. Part of this programme of work includes increasing the flow capacity at Failsworth WWTP from its current 190l/second to 350l/second. Additional storm water storage will be included in the catchment and at the works, in order to minimise intermittent discharge to the watercourse and improve river water quality. The treated water will also be required to maintain a total phosphorus concentration of less than 2 mg/l.

THE SOLUTION

On behalf of United Utilities, contract partner LiMA selected Nereda technology to meet the required effluent quality requirements. With its high effluent quality standards and small footprint, the Nereda process will provide United Utilities with an innovative and sustainable solution. The upgrade work, designed to improve river quality, will include an influent buffer and three 3000m³ Nereda reactor tanks to treat wastewater arising from 24,400 PE. The Nereda reactors will have the capacity to treat a peak flow of 1,260 m³ wastewater per hour, to ensure it can treat more of the storm water flow. In addition, 10,000m³ of additional storm water storage will be constructed at the works.

THE OUTCOME

The project is due to be operational by 2020 to meet statutory requirements. The team started on site in May 2018 and the project will be delivered and operational by end of 2019. When complete the flows will receive pre-treatment screening and de-gritting, along with tertiary treatment to achieve BOD consent of 15 mg/l.
