Wastewater treatment plants face a unique challenge balancing variable loads and power quality.
In one case, a facility upgrade included dozens of VFDs that introduced harmonic distortion. To meet IEEE 519 requirements, the initial design proposed multiple filters sized to maximum capacity.
However, a collaborative review uncovered that actual operating demand was much lower due to redundant systems.
This led to a revised harmonic mitigation approach:
• One filter no longer required
• Remaining filters significantly smaller
• Reduced system footprint
The result was a more cost-effective solution with over 40% savings and improved use of space, while meeting compliance requirements.
See how the project came together:
