Installation of the DAF C-Daf 78 C System by Urumea

KEY FEATURES  of the DAF C-Daf 78 C
 

• Optimized design: Circular flotation system with a useful diameter of 10 meters and an interior height of 2 meters.

• Stainless steel central unit: Designed to efficiently distribute water, collect sludge, and channel clarified water for maximum efficiency and durability.

• High-efficiency sludge management: Equipped with a floating sludge collector, including a transfer carriage, a sludge collection scoop, and a screw conveyor for surface evacuation, along with bottom scrapers.

• Advanced control: Adjustable speed through frequency variators in the transfer carriage and sludge extraction scoop.

• Robust materials: Constructed with AISI 304 stainless steel for all parts in contact with water, ensuring durability in demanding environments.

• Advanced microbubble technology: State-of-the-art hydrodynamic pressurization system with control loops regulating depressurization valves, ensuring the homogeneous formation of microbubbles to maximize the flotation of solids, fats, and oils.

KEY TECHNICAL DATA: 
 

• Maximum feed flow: 100 m³/h.
• Solids at inlet: <5,500 mg/L.
• Mass load: 7 kgMS/m²/h.
• Retention time: >30 minutes.
• Solids in effluent (outlet): <300 mg/L.
• Floating sludge concentration:  Up to 4% without chemicals, 6-8% with flocculant.

KEY BENEFITS :

✔ Sustainability: Maximum sludge thickening (up to 4%MS) without chemical consumption and low energy use at higher dryness levels (6-8%MS).

✔ Efficient clarification: Reduction of up to 95% of suspended solids.

✔ Resource optimization: Enhanced microbubble formation, reducing energy consumption and minimizing or eliminating chemical use.

✔ Improved anaerobic digestion at WWTP: Higher sludge dryness reduces the daily volume fed into digestion, increasing organic load, reducing HRT, and boosting biogas production.
