Biological Removal Systems
Overview
Advanced Biological Wastewater Treatment with Scalable FRC System Designs
FRC biological wastewater treatment systems use MBBR and MBR technology to remove BOD, COD, and nutrients. Compact, efficient, and scalable solutions for industrial and municipal wastewater treatment.
FRC biological treatment systems use Membrane Bioreactor (MBR) and Moving Bed Biofilm Reactor (MBBR) technologies to deliver high-performance treatment in compact, reliable designs. They reduce BOD, COD, and nutrients while minimizing footprint and operator involvement. With flexible configurations and durable construction, FRC systems provide cost-effective solutions for industrial and municipal wastewater.
Specialized plastic carrier media circulate freely in an aerated tank, providing a large, protected surface area for biofilm growth. The biofilm consumes organic matter and nutrients, naturally shedding excess biomass for removal via clarification or DAF.
Submerged ultra-filtration or micro-filtration membranes replace traditional clarifiers, filtering out biomass and suspended solids. This process produces exceptionally high-quality effluent suitable for reuse, discharge, or advanced polishing.

Biological Treatment FAQ
Q: What is the difference between MBR and MBBR wastewater treatment?
A: MBBR systems use moving carrier media for biofilm growth and organic removal, while MBR systems use submerged membranes for advanced solids separation and high-quality effluent. Both are effective biological treatment methods, but MBR produces effluent suitable for reuse or discharge without further clarification.
Q: What are the advantages of MBBR wastewater treatment?
A: MBBR offers compact footprint, resilience to shock loads, low operator involvement, and scalability by simply adding more carrier media. It is ideal for industrial plants or municipal facilities with variable influent conditions.
Q: Why choose an MBR system over conventional activated sludge?
A: MBR systems replace large clarifiers with compact membrane tanks, producing very low suspended solids effluent. This allows direct reuse of treated water, reduces space requirements, and eliminates the need for return activated sludge handling.
