Why choose hybrid filters in the water and wastewater sector?
By combining activated carbon and biological treatment, stable operation is ensured—even in humid environments where traditional carbon filters lose efficiency.
The systems are available as modular solutions, ranging from small compact units to larger, modular installations that can be tailored to any application.
The result is lower operating costs, fewer replacements, and an improved working environment for operating personnel.
The BM series – documented performance in demanding environments
BM100 – compact hybrid filter for small installations
BM100 is typically used at smaller pump stations, wastewater manholes, and decentralized installations with low to moderate airflow rates.
The unit handles air volumes of up to 100 m³/h and combines activated carbon with biologically inoculated filter mats, ensuring effective removal of hydrogen sulfide (H₂S) and ammonia—even in humid environments.
The filter is well suited for local installations where stable odor control, simple operation, and minimal maintenance are required.
BM100 can be installed as a standalone unit or integrated into existing systems and is available either as a passive, power-free solution or with monitoring for documented operation.
BM300 – hybrid filter for medium-sized installations
BM300 is used for medium-sized pump stations, sewer manholes, and wastewater installations with moderate airflow and increased requirements for odor reduction.
The filter combines activated carbon and biologically active filter mats, effectively removing hydrogen sulfide (H₂S), ammonia, and organic odor compounds—even in humid environments and under fluctuating load conditions.
BM300 has a capacity of up to 225 m³/h and is supplied either as a passive unit or with Standard A/B monitoring, enabling continuous documentation and optimization of operation.
The filter is typically installed as a stationary unit on a foundation or in a technical cabinet and is ideal for municipal and decentralized wastewater systems where stable operation and low maintenance are essential.
BM600 – hybrid filter for large installations
BM600 is used for larger wastewater installations, treatment plants, and pump stations with high airflow rates and a need for continuous, reliable odor treatment.
The filter combines biological and chemical filtration in a flexible system that is tailored to load conditions, humidity, and H₂S levels.
With a capacity of up to 600 m³/h, BM600 is ideal for installations where long service life, low maintenance, and stable operation are critical.
The filter can be supplied as a passive, power-free solution or with Standard A/B monitoring for documented performance and remote control.
BM600 is typically used at wastewater treatment plants, overflow chambers, and central air treatment systems, where effective removal of hydrogen sulfide and ammonia is essential to protect both the installation and the working environment.
BM2500 – high-capacity hybrid filter for large facilities
BM2500 is used at large wastewater treatment plants, main pump stations, and central wastewater installations where airflow rates and load levels are high.
The filter combines biological degradation and chemical adsorption through specially developed hybrid mats and is tailored to local operating conditions and pollution levels.
With a capacity of up to 2,500 m³/h, BM2500 ensures effective odor control, long service life, and low maintenance—even in humid and demanding environments.
The unit is supplied in a robust HD-PE housing and is available for passive operation or with full monitoring and documentation of treatment performance.
BM2500 is typically used in municipal treatment plants, large pump stations, and wastewater systems where high demands are placed on continuous operation and the working environment.
BM5000 – advanced hybrid filter for large central facilities
BM5000 is used at large central wastewater treatment plants, main pump stations, and industrial wastewater installations where very high air volumes and complex odor loads are handled.
The system combines biological and chemical treatment in a modular hybrid design with a capacity of up to 5,000 m³/h.
BM5000 is supplied as standard with advanced monitoring (Standard A), enabling remote control and full documentation of operation.
The filter ensures high removal efficiency, stable operation, and low maintenance—even under humid and heavily loaded conditions.
BM5000 is typically used where maximum requirements are placed on continuous air treatment, safety, and the working environment, such as at large municipal treatment plants and regional wastewater systems.
