Fully Biological Wastewater Treatment: The Fixed-Bed Process for Stability
AQUATO® 3K-PLUS
At AQUATO®, we introduce the 3K-PLUS: a reliable small WWTP that ensures consistently high purification performance through the proven fixed-bed process.
It is one of our biofilm systems and offers exceptional operational stability, even under low-load conditions and at low external temperatures. The system contains no in-tank mechanical components, utilizes wear-free tank components made from recyclable materials, and ensures maximum long-term operational safety. It is ideal for new construction or retrofitting into existing three-chamber systems

How Does the Fixed-Bed Process Work?
The Fixed-Bed Process (FB) is a proven, continuously operating method for biological wastewater treatment. It utilizes fixed-bed media where microorganisms settle to form a stable biofilm. The wastewater is then gradually passed through several chambers for step-by-step purification.
This process is simple, robust, and low-maintenance. Since the majority of biological degradation occurs directly on the fixed-bed media, the plant ensures highly stable operation, even with fluctuating loads.
Sampling takes place during the final clarification phase.
Pre-Clarification: Coarse and settleable components are removed in the first chamber to reduce the load on the subsequent biological process.
Biological Treatment (Fixed Bed) Pre-treated wastewater flows through the fixed-bed media. The settled microorganisms degrade pollutants, and intermittent aeration further supports the process for highly efficient treatment.
Final Clarification: The treated wastewater is separated from biofilm residues and activated sludge in the final chamber, then flows to the discharge. Settled solids are returned to the system.

FAQs
You have questions? We have answers!
What is special about the fixed film process of the AQUATO® 3K-PLUS?
The fixed film process utilizes tubular support media that provide an optimal habitat for cleansing microorganisms. This ensures consistently high and reliable purification performance, guaranteeing stable operation even under low-load conditions and at low external temperatures.
Are electrical components installed in the water in the AQUATO® 3K-PLUS?
No, the AQUATO® 3K-PLUS system operates without any energized or mechanically stressed components inside the tank or in the wastewater area. This maximizes operational safety and simplifies maintenance.
Can the AQUATO® 3K-PLUS be integrated into existing tanks?
Yes, the 3K-PLUS is ideally suited for retrofitting. It can be installed in existing concrete tanks. Custom adaptation to accommodate older tank sizes is also possible.
