BLACKBOX carbon filter
Ventilation with activated carbon filter removes bad odors.
Activated carbon filters the air
Is there a bad smell coming from the pumping station? Then you probably have a problem with hydrogen sulphide. BLACKBOX is an activated carbon filter that effectively removes bad odors by removing hydrogen sulfide, mercaptans and ammonia.
The activated carbon used in the BLACKBOX is designed to remove complex odor challenges that can occur, for example, in the ventilation of sewage pumping stations. In the pumping station, the air with hydrogen sulfide is drawn from the top of the odor source (sump) up through the BLACKBOX where the odor is filtered out. The air is then led out of the building.
Installation is simple and easy!
- Black box is mounted on a suitable wall
- Pipes are laid that lead the air to the carbon filter and then on out of the building
- A duct fan sucks the air through the Blackbox filter
We recommend that you first make sure to lower the moisture level in the air before the carbon filter to below 70% RH, this prolongs the carbon's ability to absorb hydrogen sulfide. If you do not reduce the humidity level, the activated carbon risks being saturated by water instead. This leads to a need to change the carbon more often.
One way is to first dehumidify the air in the superstructure with an energy efficient FLEX. If you suck the air from the sump to the carbon filter, the negative pressure created in the sump will draw down dry air from the superstructure, resulting in a lower relative humidity level.
Experience from a large number of installations with our solution Odorless climate where we use our dehumidifier FLEX together with Blackbox provides:
- That the bad smell is removed
- Energy consumption can be reduced
- You get an improved working environment
- Coal lasts longer with drier air
- Reduced maintenance costs through reduced corrosion
Blackbox activated carbon filter - an effective solution for pumping stations and wastewater treatment plants that want to remove bad odors!
- Dimensions: 500x410x940 mm
- Weight (empty): 20 kg
- Weight (with coal): 70 kg
- Connection (in and out): Ø 125 mm
- Airflow: up to 150 m3/h
The activated carbon is easily replaced when it can no longer absorb hydrogen sulphide. Regular replacement is included as part of the service contract.
