Advanced DAF Technology Revolutionizes Water & Wastewater Treatment

Jiangsu EZE Environmental Technologies. Co., Ltd-a leader in innovative water and wastewater treatment solutions, today highlighted the critical role and advantages of its advanced DAF (Dissolved Air Flotation) systems in meeting modern industrial and municipal treatment challenges. DAF technology remains a cornerstone for efficient solids separation, delivering superior clarity and operational efficiency.

How DAF Works: Precision Separation with Microbubbles

The core principle of Dissolved Air Flotation (DAF) involves supersaturating a portion of the process water with air under pressure in a dedicated saturation tank. When this pressurized water is released into the main flotation tank at atmospheric pressure, countless microbubbles (typically 20-50 microns) are formed. These bubbles attach to suspended solids, oil, grease, and other contaminants, causing them to float rapidly to the surface. A specially designed skimmer mechanism continuously removes the resulting float sludge (or scum), while the clarified water exits from the bottom. Precise control of the recycle ratio (the portion of treated water recycled for air dissolution) is key to optimizing floc formation and separation efficiency.

Superior Performance for Diverse Applications

DAF systems excel in applications where traditional sedimentation struggles, particularly with light particles, fats, oils, and greases (FOG), or high-fiber materials. Key applications include:

• Industrial Wastewater Treatment: Food & Beverage processing (meat, dairy, vegetables), Petrochemical, Pulp & Paper, Textiles, Metal Finishing.

• Municipal Wastewater Treatment: Primary clarification, tertiary treatment, thickening of biosolids or WAS (Waste Activated Sludge).

• Water Treatment: Algae removal, color reduction, pretreatment for membrane systems (RO/UF).

  Sludge Thickening: Efficiently concentrates sludge, reducing downstream processing volume and costs.

Key Advantages of Modern DAF Systems:

• High Removal Efficiency: Effectively removes suspended solids, FOG, algae, and colloidal particles.

• Rapid Clarification: Faster processing times compared to sedimentation, leading to smaller footprint requirements.

• Excellent Clarified Water Quality: Produces low-turbidity effluent suitable for discharge or reuse.

• Effective Sludge Thickening: Achieves higher solids concentration in the float (sludge thickening), reducing sludge handling costs.

• Chemical Optimization: Can reduce chemical usage compared to other methods, especially when combined with appropriate coagulants and flocculants.

• Compact Design: Ideal for space-constrained facilities or retrofits.
