The 165,000 PE works incorporating carbonaceous ASP, nitrifying BAF, as well as a strategic anaerobic digestion sludge treatment centre is at full capacity. Further process capacity concerns are linked to local development plans for project growth.
A notional solution to install additional N.BAFF cells to compliment an AMP5 scheme has been considered and are costly (ex. £3 million). The client required an appraisal to determine other technical options, as well as quantification of actual performance of the works treatment load and asset performance.
What we did
Two Optimiser units were deployed in early March just before the national Covid-19 lock down. The units were retained on site for the duration of 3 to 4 months benefiting the client with a rich data set of a large city, pre- and post-lock down. The duration offered the potential for operators to monitor process performance from their homes, as well as giving the opportunity to determine the sensor reliability when left in situ for a sustained period.
With both the Optimiser, as well as key SCADA data being surfaced to the cloud, effective integration of the data set could be readily achieved. This enabled an assessment of periods when assets were operating close to their design capacity.
In collaboration with the client’s operational team, informed interventions to optimise the works assets were conducted. The provided tools enabled rapid evaluations to take place and efficient quantification of the results to be communicated to all stakeholders.
