FBR

The fixed-bed reactor provides robust, efficient biological wastewater treatment with solid support materials.

In industrial water treatment, FBR stands for “fixed bed reactor” or fixed bed reactor. This is a type of biological reactor that is used to treat municipal or industrial wastewater through the use of microorganisms fixed on a solid support material.

How an FBR works:

  1. Backing material: In FBR, microorganisms are settled on a solid plastic carrier material. These materials offer a large surface area for biomass adhesion — even more surface area compared to MBBR.
  2. Biodegradation: Wastewater flows through the fixed bed, and the microorganisms settled on it break down the organic pollutants. The treatment can be carried out aerobically or anaerobically, depending on the type of biological processes that are suitable for the specific type of wastewater and the pollutant composition.
  3. Continuous operation: Unlike in a batch system such as SBR, the FBR typically works continuously, which makes it particularly suitable for industrial companies with a constant amount of waste water.

The FBR — benefits at a glance

raindrop icon
Space-time yield
High density of microorganisms on the carrier = high loading rate = high pollutant degradation rate
raindrop icon
Extreme robustness
FBRs are capable of effectively operating even at high pollutant concentrations. Ideal for industrial water treatment.

Low maintenance:
The solid support material requires less maintenance and monitoring compared to movable systems.
