Design, Supply, Installation, Commissioning and Acceptance Testing of Anaerobic Digestion (AD) Plant

Descriptions

The scope of this design and build project is for an overarching design and anaerobic digestion (AD) system that broadly includes: • Source separated food waste feed & ancillary system • Reception hall (A300) pit sump management system • Digester raw waste buffer tank(s) • Pump upgrades & ancillary systems • Heat exchanger upgrades & ancillary systems • Pasteurisation tank(s) & ancillary system • Effluent buffer tank(s) & ancillary system (solid-liquid separation of digestate to enable future accreditation to PAS 110) To do this, the supplier will carry out the following activities through their programme of works: • Design of the AD plant inclusive of civil engineering, structural engineering, mechanical and electrical engineering, systems engineering, and temporary works design. • Procurement and supply of AD assets whilst prioritising the Authority's key objectives of safety, reliability, efficiency, ease of maintenance, and simplicity. • Installation of assets inclusive of delivery and positioning, systems integration, control and monitoring installation, and quality and safety verification. • Commissioning activities including but not limited to system checks and functional testing, subsystem integration testing, calibration and controls, operational simulation, and regulatory compliance. • Acceptance testing to ensure the AD Plant operates at capacity, achieves design criteria, and complies with any relevant regulatory and contractual obligations.
