Anaerobic Digestion Optimisation Strategy

The strategy consisted of five key elements: Capital Intervention, a dedicated sludge management team, a ring fenced CHP maintenance budget, data management using business intelligence and a supporting optimisation programme of works.

The project objective was to uplift the outputs from the combined heat and power (CHP) generation to be in line with their installed capacity and align with industry best practice. This was therefore a Totex solution with both Capex and Opex investment required.

The investment comprised of critical capital maintenance, enhancement investment to provide standby and resilience, and instrumentation to allow a business solution to visualise, benchmark and improve outputs.

To enable an informed understanding of the works operation Aqua Consultants specified the provision of comprehensive instrumentation across the sludge stream, digesters and CHPs, with real time monitoring and reporting of data linked to a user friendly dashboard to inform the operator/management. The Aqua Consultants dashboard will also report the financial implications of reduced performance, linking the process relationships of each process stage and reporting outputs as financials.

The investment will provide a resilient and robust AD sludge treatment operation, to deliver an uplift of 90% in CHP generation compared to historic performance.
