The Technology

How does a utp fixed-bed reactor / FBR-container work?

A cascaded fixed-bed system is based on multiple reaction stages connected in series, each equipped with specifically adapted carrier materials (biofilm carriers). As the wastewater flows through each reactor stage sequentially, each stage provides an optimally designed surface for microorganisms to colonize.
The pollutant concentration decreases from one stage to the next, allowing microorganisms in each stage to adapt to the specific conditions and pollutant levels present there.

The cascaded structure ensures particularly efficient utilization of microorganisms, as each stage operates under ideal conditions that are precisely tailored to the specific pollutant loads. This allows a step-by-step and targeted degradation of a wide variety of contaminants.
As a result, the system can be precisely adapted to different requirements, such as fluctuating wastewater compositions or varying flow rates.

Thanks to this mode of operation, the efficiency of the treatment process is maximized, while at the same time a high level of stability is maintained. The cascaded fixed-bed system thus offers a reliable and high-performance solution for demanding tasks in wastewater treatment.

The general process flow:

1. Inlet: Primary treatment of the wastewater to remove inorganic substances.
2. Biological treatment: The wastewater flows through the cascaded fixed bed. Oxygen is introduced by an energy-efficient ventilation system.
3. Secondary treatment: Separation of the sludge from the treated wastewater
4. Automatic control: Adjustment to the given conditions
