VTA Calcoferrit®, the uncomplicated, efficient protection against odor and corrosion in the sewer

Odors from wastewater systems and sewers are a problem in many places. They are not only annoying, but can also pose a health risk.

The solution: VTA Calcoferrit®. It also suppresses the formation of biogenic sulphuric acid, which leads to corrosion damage to the sewer system. VTA Calcoferrit® therefore reduces the costs for maintenance and renovation!

Possible combination

VTA underground tank

The VTA underground tank is the best option for storing VTA system products for odour control below ground and for dosing.

Foul odours from the sewer and concrete corrosion on the infrastructure are effectively eliminated and prevented by VTA’s highly effective ‘odour killers’. Where these system products are in use, however, the question often arises, particularly in pumping stations, of what the best option is for storing and dosing them.

The solution is the VTA underground tank, a double-walled storage tank made of polypropylene, available in various sizes from 1 – 3 m3. Thanks to its corrugated profile, the outer wall is particularly resistant and able to reliably withstand compressive stresses from the ground earth. The interstitial space is monitored by a leakage sensor.

How the innovative system solution works

By preventing anaerobic conditions, metabolic pathways are prevented which result in the formation of hydrogen sulphide and other odorous substances, as well as a corrosive effect on the infrastructure. A further component ensures the elimination of existing odorous substances.

It is not unusual for VTA Calcoferrit® to dispense with control and regulation technology. So simple, so effective!

On customer request, we offer online monitoring and H2S-controlled dosing for secure documentation of your data.

H2S monitoring

With H2S monitoring and highly effective special products, VTA reliably ensures that odours are eliminated even under difficult conditions. Using the latest measuring and control technology makes odour control particularly economical and user friendly. VTA offers the option of remote monitoring  and control using H2S monitoring: dosing is controlled online via the H2S server (H2S sensor, GPS terminal). VTA offers the full complete package for this purpose on request. 


VTA Calcoferrit® in practice

Simply good. Twice as effective.

VTA Calcoferrit® is effective wherever odorous substances can escape between discharge into the sewer system and the wastewater treatment plant.
