Skimmer Adjustments on a DAF System

This instructional video provides detailed guidance for adjusting the skimmer blades on an FRC Dissolved Air Flotation (DAF) system to achieve smooth and reliable sludge removal.

Key adjustments covered:

• Setting Nylock fasteners loose enough for minor lateral movement

• Ensuring skimmer blades do not rub against the DAF tank sidewall

• Adjusting chain tension and length so blades lift only ~1 inch off the guide rail

• Identifying and correcting chain sag around sprockets

• Raising or lowering water level with the adjustable weir

• Using the variator to fine-tune skimmer spread

Proper setup prevents wear, reduces downtime, and delivers consistent float performance.
