The wastewater gas problem

Gas formation, pressure and odour are part of the wastewater environment.

Wastewater systems are dynamic environments. Flow conditions, residence time, biological activity and oxygen availability can influence the formation and movement of sewer gases. TASOTFILT is designed to address these conditions at access points and within selected wastewater treatment applications.

Hâ‚‚S

Hydrogen sulfide

Hâ‚‚S is associated with characteristic sewer odour, corrosion and health and safety concerns, particularly where gas can accumulate in enclosed wastewater environments.

Oâ‚‚

Oxygen availability

Low dissolved oxygen conditions can favour anaerobic processes in wastewater and contribute to sulfide formation.

↔

Gas movement

Air and wastewater gases move through manholes and pipelines as pressure and flow conditions change throughout the system.

âš 

Infrastructure risk

Sulfide-related conditions can contribute to corrosion and operational problems within wastewater infrastructure.

â—Ž

Odour at the source

Treating or filtering wastewater gases close to their point of release can reduce the need to manage odorous gas farther downstream.

âš™

Practical installation

TASOTFILT systems are developed around compact installation, accessible cartridges and practical field maintenance.

Product systems

Three technologies for different wastewater conditions.

TASOTFILT Type 4
Type 4 4-layer cartridge

TASOTFILT Type 4

A compact passive filtration system developed for outdoor manhole applications. The Type 4 cartridge is designed for wastewater gas and odour control without electrical power.

Technical Information
TASOTFILT Type 12
Type 12 12-layer cartridge

TASOTFILT Type 12

A multi-layer cartridge system developed for higher gas-load applications. Its staged media structure is designed to reduce preferential flow paths and improve utilisation of the filtration media.

Technical Information
TASOTFILT BIO
BIO Biological treatment

TASOTFILT BIO

A biological filtration system developed for wastewater pumping stations, deep collector manholes and inspection chambers, using a continuously wetted medium and biological activity for Hâ‚‚S control.

Technical Information
ENGINEERING & TECHNOLOGY

Designed around how wastewater gases actually move.

TASOTFILT combines passive filtration, staged media and biological treatment technologies. Each system addresses wastewater gas conditions in a different way.

TYPE 4 Passive system

Compact passive filtration

A compact passive filtration system designed for outdoor manhole installation and wastewater gas and odour control without electrical power.

TASOTFILT Type 4 is designed for outdoor installation beneath manhole covers. Sewer gases generated within the wastewater system can move through the manhole as pressure and flow conditions fluctuate. When a filter is installed, the gas stream passes through the cartridge before reaching the surrounding environment.

The system requires no electrical power. The cartridge can be accessed and replaced without special tools, supporting practical field maintenance.

  • Outdoor installation
  • No electrical power consumption
  • Quick cartridge access and replacement
  • Designed for harsh environmental conditions
  • Reference service life based on Hâ‚‚S concentration and gas flow
TYPE 12 Multi-layer media

Twelve-layer filtration architecture

A staged multi-layer cartridge developed to reduce preferential flow paths and improve utilisation of the filtration media.

Read more Read less +

Field testing identified preferential flow paths within filter media that could reduce effective media utilisation and shorten cartridge service life. The Type 12 design was developed to address this behaviour through a staged, multi-layer filtration structure.

TASOTFILT Type 12 consists of 12 filtration layers, each 4 cm thick. The carbon-containing initial stage is designed to condition and homogenise the incoming gas before it enters subsequent filtration stages.

This promotes broader use of the cartridge rather than allowing the gas stream to remain concentrated along a preferential path.

The cartridge incorporates six dry-chemical layers, five of which contain carbon. The combination of dry chemical media and carbon forms the filtration structure developed for higher gas-load applications.

BIO Biological system

Biological Hâ‚‚S control at the source

A biological treatment system designed to address Hâ‚‚S close to its source using a continuously wetted medium and biological activity.

Read more Read less +

TASOTFILT BIO is designed for wastewater pumping stations, deep collector manholes and inspection chambers. Instead of transporting contaminated gases through additional pipework, the system is designed to address Hâ‚‚S close to its source.

The system uses a dedicated monofilament medium that is continuously wetted with wastewater. This creates the moist surface required for biological activity and supports the presence of Sulfobacter oxydans within the system.

A portion of the wastewater is pumped through the system, distributed across the medium and returned to the wastewater stream. This closed-loop circulation supports continuous wetting and biological activity.

Applications

Engineered for wastewater infrastructure.

TASOTFILT systems can be applied at locations where wastewater gases, odour and Hâ‚‚S-related conditions require practical control close to the source.

01

Wastewater pumping stations

Suitable for environments where wastewater residence time, biological activity and gas accumulation can become operational concerns.

02

Deep collector manholes

Compact filtration and biological treatment options for deeper wastewater collection structures.

03

Inspection chambers

Manhole-mounted filtration designed to intercept gases before they are released around access points.

04

Collector networks

Solutions for wastewater networks where pressure fluctuations and gas movement can contribute to odour release.

05

Municipal infrastructure

Compact systems suitable for urban wastewater infrastructure where odour control is important to surrounding communities.

06

Industrial & commercial sites

Applications where wastewater gas control must be integrated into existing infrastructure with minimal installation space.
