EcoBox – Compact, efficient, digitally cleaned
The EcoBox SBR is a compact, biological wastewater treatment plant for the reliable purification of domestic wastewater using the proven SBR (Sequencing Batch Reactor) process. The system is delivered pre-assembled and ready to plug in, enabling particularly quick and easy installation – even in confined spaces.
Thanks to its slim, rectangular design, the EcoBox offers flexible placement options and is ideal for single-family homes, small apartment buildings, and properties without a sewer connection or with limited space.
The robust PE tank with an integrated partition ensures high stability and durability, while two telescopic, walk-in access panels provide convenient access for maintenance and servicing.
Overall, the EcoBox SBR combines modern wastewater technology, digital control, and minimal maintenance requirements in a compact system – a future-proof solution for decentralized wastewater treatment.
The EcoBox in detail
A key feature of the EcoBox is its digital operation via telemetry. The system is automatically monitored daily, malfunctions are reported immediately, and the operating log is maintained digitally on a monthly basis. This significantly reduces the manual effort required from operators – operator responsibilities can be completely handled by a maintenance company.
In addition to its high operational reliability, the EcoBox also offers clear economic advantages: Maintenance intervals can be reduced from the third year of operation onward, resulting in long-term cost savings. The combination of automated monitoring, an efficient cleaning process, and simple installation makes the system particularly efficient and economical to operate.

- The air supply lines are not included. Four DN 16 hoses are required.
Telemetry / Data Transmission
DIGITAL OPERATION
Telemetry enables us to offer you comprehensive service for the operation and maintenance of your system.
REDUCED MAINTENANCE
For a small wastewater treatment plant equipped with telemetry/electronic data transmission, the maintenance frequency can be reduced starting in the third year of operation.


OPERATOR MONITORING
As the operator of a small wastewater treatment plant, you are required to perform various checks on your system. Your maintenance company can handle these operator obligations for you using telemetry/electronic data transmission. Without any additional effort on your part, the system status is retrieved daily, the operating log is automatically maintained monthly, and any malfunctions are reported immediately.
How SBR wastewater treatment works
The EcoBox small-scale wastewater treatment plant uses the SBR (Sequencing Batch Reactor) process for the biological treatment of wastewater. The system consists of two sections:
- Sludge storage
- SBR reactor
The treatment process is automated and takes place in several phases:
- Reactor filling
- Biological treatment by microorganisms
- Sedimentation of solids
- Clear water discharge
The treated water can then be discharged in accordance with local regulations.
