Industry
Municipal / Water Utilities
Services delivered
- Control system modernization design and installation
- Aeration system upgrade
- On-site operational optimization
- Energy efficiency program qualification
The challenge
The plant faced multiple challenges: an outdated control system rendered inoperable by age and lightning damage, inefficient aeration control, and high energy consumption.
Our approach
Results
15% energy consumption reduction in the first year. After the six-month optimization period, energy reduction reached 25%. Achieved 0.75 kWh/m³ specific energy consumption. The total project investment cost recovered within 12 months. The electrical consumption reduction qualified the project for the White Certificate in Hungary's EKR system, allowing sale of Certified Energy Savings (HEM) — further improving payback.
Key outcomes
15% energy consumption reduction in first year
25% energy reduction after 6-month optimization
0.75 kWh/m³ specific energy consumption achieved
Full project payback within 12 months
Eligible for White Certificate (HEM) sale in EKR system
Key lesson
WWTP automation delivers the largest savings in energy, chemicals, and human resources. Automation development is a fast-payback investment. Modern control systems and proper instrumentation significantly reduce operating costs. On-site expert optimization is key to maximum efficiency. Energy efficiency program participation can provide additional financial benefits.
