Fixed Film Systems

SSI’s Moving Bed Biofilm Reactor (MBBR) technology delivers exceptional performance for wastewater treatment plants. Key benefits include:

• High Treatment Efficiency – MBBR systems provide a large protected surface area for biofilm growth, enabling superior biological treatment.
• Compact Footprint – Ideal for facilities with space constraints, MBBR systems require smaller tanks compared to conventional systems.
• Low Maintenance – No sludge recycling and minimal operator intervention reduce operational complexity.
• Scalable and Flexible – Perfect for new installations or retrofits in municipal and industrial applications.
• Energy Efficient – Designed to optimize aeration and mixing, reducing energy consumption while maintaining performance.

A successful MBBR system depends on uniform distribution of media and oxygen throughout the tank. SSI’s design ensures:

• Advanced Diffuser Technology – Provides even oxygen transfer and mixing.
• Reliable Media Retention Screens – Prevents clogging and guarantees smooth media movement.
• High-Performance Media – SSI offers carriers engineered for maximum biofilm growth and durability.

Poor mixing can lead to dead zones, reduced treatment efficiency, and uneven biofilm growth. SSI’s MBBR systems eliminate these issues through precision aeration and optimized tank hydraulics.

Integrated Fixed-Film Activated Sludge (IFAS) combines suspended growth (activated sludge) with attached growth (biofilm) in the same reactor. This hybrid approach:

• Increases treatment capacity without expanding tank volume.
• Improves nitrification and denitrification performance.
• Offers a cost-effective upgrade for existing activated sludge plants.

• Decades of experience in wastewater treatment innovation.
• Comprehensive product line including MBBR and IFAS systems.
• Expert engineering support for design, installation, and optimization.
