The paper recycling industry faces unique challenges, including fiber recovery, efficient resource use, and waste reduction. The Krofta Spray Filter is an innovative solution designed specifically to address these challenges, enhancing recycling efficiency and sustainability. With its advanced fractionation technology, it provides unmatched benefits to de-inking mills and recycling plants.

The Krofta Spray Filter specializes in recovering valuable long fibers from waste streams, a critical advantage in de-inking operations where up to 35% of solids can be lost:

• Minimized Fiber Waste: Captures the long fiber fraction, reducing losses and improving recycling efficiency.
• Clean Fiber Output: Produces high-quality fibers with minimal ash content, ready for reintegration into the production process.
• Increased System Efficiency: Enhances the recycling process by reducing fiber loss, boosting output, and maximizing resource utilization.

By reducing fiber waste and improving recovery rates, the Krofta Spray Filter delivers significant cost savings:

• Lower Furnish Costs: Recovered fibers replace new furnish, saving $1500–$2500 per day at a 5-ton recovery rate.
• Reduced Disposal Expenses: Decreases sludge volume sent to landfills, cutting disposal costs by approximately $1000/day.
• Short-Term ROI: With both cost reductions and operational efficiency gains, the Spray Filter provides a rapid return on investment.

The Krofta Spray Filter uses advanced spray and screen systems for precise fiber fractionation:

• Fine Mesh Screens: Operates with screen openings as fine as 155 microns, enabling effective separation of fibers from fines and ash.
• Self-Cleaning Design: The rotating drum screen’s natural fluttering motion prevents clogging and maintains filtration efficiency.
• Backwash System: Periodic cleaning ensures consistent performance and minimizes maintenance.

The Krofta Spray Filter supports environmentally friendly operations by reducing waste and maximizing resource recovery:

• Waste Reduction: Decreases landfill sludge volumes by recovering usable fibers.
• Water Reuse: Integrates seamlessly with clarifiers like Krofta Supracell for water recycling, reducing freshwater consumption.
• Lower Carbon Footprint: Enhances resource efficiency, supporting sustainable paper recycling practices.

The Krofta Spray Filter optimizes the paper recycling process by effectively managing waste streams:

• Ash and Fines Removal: Separates unproductive fines and ash, leaving behind clean fibers for reuse.
• Integrated Solutions: Works alongside de-inking systems and clarifiers to enhance overall plant performance.
• Versatile Applications: Suitable for writing, printing paper, and tissue production, accommodating a variety of recycling needs.

The Krofta Spray Filter stands out from competing technologies due to its focus on fiber fractionation. Unlike standard gravity or vibrating screens, it efficiently separates long fibers without mat formation, ensuring high recovery rates and clean output.

With its proven performance, sustainability benefits, and cost-saving potential, the Krofta Spray Filter is an invaluable asset for the paper recycling industry.
