Proven DAF Excellence for Over 50 Years

For decades, Krofta has led the way in Dissolved Air Flotation (DAF) technology, providing efficient and innovative solutions for wastewater treatment. With a legacy of more than 60 years and installations in over 3,000 facilities worldwide, Krofta DAF systems are trusted for their unmatched reliability, superior performance, and commitment to sustainability.

Krofta DAF systems utilize the principle of dissolved air flotation to separate suspended solids from wastewater. Compressed air is dissolved into the water through Krofta’s patented Air Dissolving Tube (ADT), creating microbubbles. These microbubbles adhere to solid particles, lifting them to the water’s surface, where they are skimmed off as sludge. The clarified water below is then discharged for reuse or further treatment.

Dissolved Air Flotation (DAF) is an efficient solution for liquid-solid separation because of its ability to effectively remove suspended solids, oils, and other contaminants from wastewater with minimal energy and chemical usage. Here's why:

1. Microbubble Technology: The DAF process generates microbubbles that attach to suspended particles, reducing their density and causing them to float to the surface for easy removal.

2. High Separation Efficiency: DAF systems can achieve high rates of particle removal, including fine and lightweight particles, which are often challenging for other separation methods.

3. Reduced Chemical Consumption: While coagulation and flocculation are optional, DAF systems often require fewer chemicals compared to sedimentation or other methods.

4. Compact Design: DAF systems, such as Krofta DAFs, are designed for high flow rates in a smaller footprint, saving space and installation costs.

5. Customizable Process: The process can be tailored to specific wastewater compositions, making it versatile for industries like food processing, paper, textiles, and municipal treatment.

6. Sustainability: DAF systems enable water reuse by efficiently clarifying process water, reducing environmental impact, and supporting zero-discharge goals.

The combination of efficiency, adaptability, and cost-effectiveness makes DAF a superior choice for liquid-solid separation in diverse applications.
