BLACKBOX carbon filter
Ventilation utilizing an activated carbon filter eliminates unpleasant odors.
Activated carbon filters the air
Experiencing foul odors from the pump station? You likely have an issue with hydrogen sulfide. BLACKBOX is an activated carbon filter that effectively eliminates unpleasant odors by removing hydrogen sulfide, mercaptans, and ammonia.
The activated carbon used in BLACKBOX is engineered to address complex odor challenges, such as those arising from the ventilation of wastewater pump stations. Air containing hydrogen sulfide is drawn from the upper section of the odor source (the wet well) up through the BLACKBOX, where the odors are filtered out. The purified air is then discharged from the building.
The installation is simple and straightforward!
- The Blackbox is mounted on a suitable wall.
- Ducting is installed to direct the air to the carbon filter and subsequently out of the building.
- An inline duct fan draws the air through the Blackbox filter.
We recommend first ensuring that the humidity level of the air entering the carbon filter is reduced to below 70% RH, as this extends the carbon's capacity to absorb hydrogen sulfide. If the humidity level is not reduced, there is a risk that the activated carbon will become saturated with water instead, leading to the need for more frequent carbon replacements.
One approach is to first dehumidify the air in the upper structure using an energy-efficient FLEX unit. By drawing air from the wet well to the carbon filter, the negative pressure created in the well will pull dry air down from the upper structure, resulting in a lower relative humidity level.
Experience from a large number of installations featuring our Odour-free climate solution, where we combine our FLEX dehumidifier with the Blackbox, demonstrates:
- The elimination of unpleasant odors
- Reduced energy consumption
- An improved working environment
- Extended carbon lifespan due to drier air
- Lower maintenance costs achieved through minimized corrosion
Activated carbon filter with Blackbox – an efficient solution for pump stations and wastewater treatment plants seeking to eliminate bad odors!
- Dimensions: 500x410x940 mm
- Weight (empty): 20 kg
- Weight (with carbon): 70 kg
- Connections (inlet and outlet): Ø 125 mm
