Data-driven diagnosis of operational performance issues
Helping industrial clients troubleshoot issues and improve efficiency of existing processes.
When operational data isn’t delivering answers
Many treatment plants generate large volumes of data, but still struggle to understand what is really happening. Common issues include:
Underperforming processes with no clear root cause
Rising energy or chemical costs without explanation
Unstable or inconsistent system behaviour
Conflicting interpretations between operators, engineers, and vendors
When this happens, decisions are often made on assumption rather than evidence, leading to missed opportunities or misdirected interventions.
Independent data-driven process diagnosis
Promethean Engineering provides independent analysis of operational data to establish a clear, trusted view of system performance.
We focus on understanding how the system is really behaving and not just what the headline metrics suggest.
By combining engineering judgement with data analytics, we separate:
Real process behaviour from measurement noise
Operational issues from design limitations
Short-term variability from long-term trends
This creates clarity where uncertainty previously existed.
How we work
Our approach is structured but pragmatic, using available plant data to build a reliable understanding of performance:
Establish a clean operational baseline from available data.
Identify leading indicators of instability and inefficiency
Diagnose root causes across process, control, and infrastructure
Quantify performance improvement opportunities
Support implementation of targeted operational changes
We do not rely on generic optimisation models and every analysis is grounded in the actual behaviour of your system.
What this enables
This approach provides:
Clear understanding of why performance issues are occurring.
Reduced uncertainty in operational and technical decision-making.
Identification of hidden cost drivers (energy, chemicals, downtime).
Evidence-based prioritisation of improvement actions.
Confidence in whether further capital investment is required.
Benefits for your organisation
Cost reduction by proactively identifying and addressing inefficiencies before they escalate (e.g., unplanned downtime, overdose of chemicals).
Risk mitigation through early detection of potential asset failures or quality breaches.
Enhanced sustainability via lower consumables usage, energy optimisation and improved resource recovery.
Better decision making by transitioning from gut feel or historical precedent to data driven insight.
Our Approach
Promethean Engineering can empower your operational teams to reduce costs and make better decisions by first understanding the root causes of issues, to then outline options for optimisation.
1. Define Success Criteria
- For example; Cut specific energy of RO permeate production by 0.1 kWh/m³, reduce
anti-scalant use by 15% or raise RO recovery from 75 → 80%.
2. Instrumentation and Infrastructure Audit (Desktop & Site)
3. Establish Baseline KPI’s
- Review existing site data. Identify data gaps and establish a plan to obtain.
- Establish baseline performance form existing data.
4. Descriptive Statistics and Exploratory Analytics
- What happened? (summerise past events).
5. Diagnostic Analytics
- Why did it happen? (Root cause analysis)
6. Predictive Analytics
- What will happen? (Forecast future states)
7. Prescriptive Analytics (Optimisation and recommendations)
- How can we make it happen? (Optimal Action)
- Determine the best operating strategy given predictions and constraints.
7. Monitoring, Validation & Continuous Improvement
Why Work With Us?
We combine over 20 years of experience in the design and build of waste water treatment and reuse systems with an independent, client first approach. Unlike technology vendors, we don’t push a single technical solution, we evaluate options to find what’s best for your operation. We understand the need to develop a solid foundation in a projects planning stages to increase its overall likelihood of success.
Our background spans the UK and North & South America, supporting clients in food, beverage, whisky, dairy, and industrial sectors. We focus on practical, sustainable designs that balance performance, cost, and long term resilience.
