Efficient wastewater treatment is a critical need for the protein and meat industry, where high levels of fats, oils, grease (FOG), total suspended solids (TSS), and biochemical oxygen demand (BOD) must be managed.

Krofta Dissolved Air Flotation (DAF) systems deliver superior performance in treating kill plant effluent for beef, pork, and poultry processing plants.

Compared to traditional clarifiers and competing DAF systems, Krofta DAF technology provides unparalleled efficiency and flexibility.

Krofta DAF systems are available in multiple configurations to meet the diverse needs of protein processing facilities:

• Two-Stage DAF Systems: Often, two DAFs are used in series for optimal treatment. The first DAF operates without chemical additives to recover FOGs for reuse, while the second uses chemical treatment to achieve the highest water quality for downstream processes.
• Customizable Solutions: Krofta DAF systems can be adapted for various stages of wastewater treatment, ensuring compatibility with existing plant setups.

Krofta DAF technology is highly effective in reducing key pollutants commonly found in protein and meat processing wastewater:

• Standalone Solutions: Can be implemented as a primary treatment option to reduce FOG, TSS, and insoluble BOD/COD levels before discharge.
• Integration with Biological Processes: Acts as a pretreatment or post-treatment step to enhance the performance of biological processes by removing solids and oils that could disrupt microbial activity.

Key Benefits: Improves effluent quality, reduces environmental impact, and minimizes operational costs.

In beef processing plants where hides are processed on-site, Krofta DAF systems address the unique challenges of high-solids effluents:

• TSS Reduction: Efficiently removes suspended solids from wastewater streams in hide processing operations.
• Brine Reuse: DAF systems enable the treatment of high-concentration brines, reducing TSS to allow reuse in processes. This minimizes reliance on disposal wells or costly off-site brine transport.

Key Benefits: Enhances sustainability by reducing waste and supporting water reuse initiatives.

Krofta DAF systems outperform traditional clarifiers and other DAF designs in several key areas:

• Shorter Treatment Time: Rapid clarification in just 3-5 minutes.
• Higher Solids Loading Capacity: Handles higher concentrations of FOG and TSS without compromising performance.
• Smaller Footprint: Requires less space compared to conventional systems, making it ideal for facilities with limited available area.

By integrating Krofta DAF technology, protein and meat processing plants can achieve:

• Regulatory Compliance: Meets stringent discharge standards for wastewater quality.
• Sustainable Operations: Supports resource recovery, such as FOG reuse and brine recycling, reducing waste and improving efficiency.
• Cost Savings: Minimizes operational costs by improving process efficiency and reducing the need for external waste disposal.
