About the system
What Tasotfilt does
Tasotfilt is a filtration system mounted under the manhole cover to capture hazardous gases, reduce odor release, support cleaner air in urban environments, and protect wastewater infrastructure from contamination-related risks.
🌍
Cleaner urban air
Helps improve environmental conditions by reducing odor emissions and limiting the release of harmful gases into the atmosphere.
🛡️
Barrier for harmful organisms
Acts as a defensive layer against rats, insects, flies, mold spores, bacteria, and viruses moving from wastewater lines toward living spaces.
🏙️
Public health support
Reduces odor nuisance and contamination transfer in municipalities, office buildings, malls, amusement parks, and mixed-use urban projects.
🪨
Debris entry reduction
Helps prevent sand, stones, and wind- or rain-carried debris from entering wastewater systems through manhole openings.
⚙️
Lower maintenance burden
Supports smoother operation by helping reduce blockages, overflows, pump issues, pest control needs, and avoidable intervention costs.
System categories
Filtration solutions by operating requirement
The product family is organized for different concentration thresholds and application environments, making it easier to match the right system to the site.
TASOTFILT Type 4
If the maximum gas concentration reaches up to 20 ppm, the 4-layer cartridge system is the recommended option for balanced performance and compact deployment.
TASOTFILT Type 12
For higher gas concentration environments, the 12-layer cartridge system provides a stronger filtration structure suited to more demanding wastewater conditions.
TASOTFILT Bio
A biofilter system developed for pump stations, collectors, and inspection manholes where biological treatment characteristics are beneficial.

Technical overview
Design and functionality
Tasotfilt is designed so that gases follow the longest possible path within a minimal volume, maximizing contact with the filtration media while allowing gas and water passage without pressure buildup.
The role of oxygen in wastewater systems
One of the main problems in wastewater pipelines is oxygen drop. When biodegradable materials decompose rapidly due to bacterial activity, oxygen decreases and anaerobic conditions begin to form. Tasotfilt helps regulate the controlled release of pressurized air from manholes, supporting fresh air movement through the line and promoting a more stable aerobic environment.
During low-flow periods such as nighttime, oxygen levels can fall quickly and harmful gases may accumulate. When flow rises again, those gases and pH-related effects may stress structural components. In these conditions, controlled air balance becomes especially important.
Filtration mechanism
- The filter cartridge uses interwoven labyrinths that guide gases in a helical motion toward the center.
- As gases pass through the filter, they contact the media, separate molecular structures, and support capture reactions.
- The media chemically binds harmful gases through Van der Waals forces.
- Certain bacteria on the media surface can become active and contribute to gas breakdown.
- A dry chemical section in the center helps neutralize harmful organisms before clean air is released.
Durability and maintenance
Materials used in the filter assembly are selected to withstand aggressive wastewater conditions, including low pH environments. Mounting brackets are stainless steel, the housing is rigid polyurethane, and the cartridge is recyclable polyethylene.
During maintenance, only the cartridge is replaced while the other structural elements remain fixed, supporting practical long-term operation.
Safety and future direction
- The filter is buoyant and will not sink if dropped into wastewater.
- A safety ring helps prevent loss if the unit becomes dislodged.
- The ring is typically secured to the manhole cover hinge for added stability.
- Future developments may include beneficial bacteria transfer concepts that further support treatment efficiency and circular wastewater ecosystem goals.
