Under this early contractor involvement (ECI) project, Murphy collaborated with Northern Ireland Water and Royal Haskoning DHV to develop, construct and commission a solution for a 50,000 PE expansion of Dungannon WWTW using the Nereda® aerobic granular sludge process.
Dungannon WWTW was a plant with process equipment reaching the end of its useful life, a rising hydraulic and biological load and a high industrial in the influent. The challenge in this project was to deliver a solution which:
Delivered new infrastructure consistent with NI Water standard specifications.
Satisfied the NI Utility Regulatory requirement use of contemporary treatment technology with high OPEX efficiency for large scale treatment facilities.
Provided NI Water with a test facility to measure the performance of the Nereda® process with a view to future investment decisions.
Project Delivery & Innovations
Murphy as the lead process contractor was responsible for overall project design, project management and procurement of all equipment, including fulfilling the role of Principal Designer.
The solution developed by Murphy Process Designer in association with the patent holders, RHDHV, was for a two tank NEREDA® solution for 50,000 PE with space allocation for a further 50,000 PE, meaning that the works will be able to cope with its increasing current demand and maintain regulatory compliance.
The overall solution delivered by Murphy included:
Forward feed and NEREDA® reactor feed pumping stations.
NEREDA® aerobic granular sludge reactors.
Fats, oils and grease removal system.
Flow buffering and distribution systems.
