H2S database

Online sensor to combat foul odours


The H2S reducer from VTA forms the basis for efficient and reliable odour prevention in sewer systems.

It collects hydrogen sulphide data via a network of online measuring sensors and controls the associated dosing systems. Data exchange is fully automated via GPRS connections. All data (for example, measurement curves) can be retrieved online. Request your  test access

Hydrogen sulphide (H2S) is colourless, highly toxic, highly flammable and has a characteristic pungent stench of rotten eggs. It occurs when anaerobic conditions prevail in wastewater, for example in pressure lines. H2S assaults not only the olfactory nerves, but also the infrastructure through corrosion.

VTA system products for combating digester gas, such as the ‘odour killers’ Calcoferrit and Dolomin, do not allow H2S to develop in the first place. This means they reliably prevent foul odours and corrosion damage.

Odour can be controlled particularly economically by using state-of-the-art measurement, control and regulation technology in the form of the VTA H2S sensor. This user-friendly method allows the development of H2S to be monitored and assessed online from the comfort of your office.

Possible combination


Odours from wastewater systems and sewers are a problem in many places. Not only are they irritating, they are also a danger to health.

The solution: VTA Calcoferrit®, the simple, efficient and organic way to stop odour in its tracks.

It also suppresses the formation of biogenic sulphuric acid that leads to corrosion damage in the sewer system. This can considerably reduce the costs of maintenance and repair.

Effective, active in many ways, cost-effective & uncomplicated: VTA Calcoferrit® in, odour out.

The VTA underground tank offers the option to store and dose VTA system products for odour control, for example, VTA Calcoferrit®, below ground – the main area of application for the tank is in pumping stations in the municipal sector.

The corrugated profile of the outer wall of the double-walled storage tank is particularly resistant and able to withstand compressive stresses from the ground earth.

Positioning the technical equipment in the manhole pit means that it is easily accessible at all times.

The products are dosed using state-of-the-art membrane dosing pumps, while the interstitial space is monitored using a leakage sensor.
