Peel Common WwTW Upgrade
This EPC Contract involved replacement of the existing inlet works and an upgrade of the sludge dewatering facilities, including new centrifuges, feed pumps, polymer dosing, cake handling systems and a new odour control system. Early into design, we identified an opportunity to provide multiple operational, financial and safety benefits by rearranging plant layouts. Our innovative design:
- Eliminated H&S concerns
- Accelerated the construction and commissioning programme
- Enabled uninterrupted use of the existing sludge dewatering system
Peel Common WwTW treats wastewater from the Fareham and Gosport catchments in Hampshire, with a total population equivalent of 250,000.
Sludge Dewatering: three Alfa Laval centrifuges were provided, the installation being designed to provide maximum ease of operation and allowance for future expansion.
Sludge Feed: New dedicated feed pumps were installed and tested whilst existing press feed pumps remained in service.
Polymer make-up, storage and dosing: Designed to be installed in two phases to ensure continuing dosing capability.
Cake collection system: Comprising six fully enclosed and odour controlled, auto sequenced RORO containers.
Odour Control Unit: Two-stage bio-scrubber and secondary carbon filter.
MCC: Designed, installed and commissioned by our Controls Division, TSE. Overall plant control achieved utilising PLC, HMI and SCADA.
Inlet Works: New Inlet Screens, incorporating a late change in design flow requirement. Combined wash compactors and screenings launder. Our design team created a fully automated trap chute connecting to the existing removal conveyor, reducing operator intervention.
