Save millions instead of building them

VTA Nanocarbon® is dosed directly into the existing biological stage.

No construction work required.

In the video: the VTA Nanocarbon Ionization System — fully containerised, plug and play, ready for immediate operation.

€8–11 million lower total cost over 10 years

compared to granular activated carbon, for a plant serving 100,000 PE.

  • €350,000–500,000 investment instead of €6.0–9.5 million for GAC
  • No filter structures, ozone generators or oxygen tanks
  • Ultrasonically ionised — higher performance at lower consumption

Model calculation for 100,000 PE excluding ancillary construction costs, based on the expert report of 07/2026. Worldwide patent pending.

Thanks to the special and innovative structure of VTA Nanocarbon® with the greatest

possible active surface area, a far-reaching removal of anthropogenic trace substances, microplastic particles and AOX can be achieved in the existing cleaning system in a low-energy way, even with the smallest dosage quantities.

VTA Nanocarbon® can remove up to 99% of microplastic particles, especially in the lower micrometer range.

By using VTA Nanocarbon®, additional pollutant parameters that are not naturally degradable, such as AOX up to 93%, can be bound from the wastewater.

VTA Nanocarbon® replaces the 4th purification stage

The Liquid Engineering process using VTA Nanocarbon® guarantees high removal rates of trace substances

without expensive investments for conversion and expansion work, as well as the energy-intensive operation of a 4th treatment stage.

Alternative to the 4th cleaning stage

Headmaster Thomas Heppner confirms practical use

VTA Nanocarbon® marks a significant advance in wastewater treatment as the latest development in

the VTA Liquid Engineering series.

Reduction of ventilation energy

The compact floc structure is permeable to diffusion, allowing the oxygen introduced to be used optim

ally. This makes it possible to reduce aeration energy in the activated sludge stage by up to 30% and therefore represents an important contribution to energy and climate neutrality in the wastewater sector.

Increasing the cleaning performance of wastewater treatment plants

By maximizing the settling speed of the solids, a high level of operational reliability is ensured

, even under high hydraulic loading. In addition, biological activity is increased and the treatment performance of the wastewater treatment plant is enhanced.

Sedimentation

Several series of tests confirm: VTA Nanocarbon® leads to a significant improvement in sedimentation

behavior and settling speed and improves sludge properties, resulting in an optimal and compact floc structure.

Micropollutants - Danger to Humans and the Environment

At the current state of the art, wastewater treatment plants are not able to retain or break down

the micropollutants introduced by humans, so that rivers, lakes and even groundwater are polluted. Microplastics also pose an ever greater threat to people and the environment, with especially the smallest, health-relevant plastic particles being insufficiently removed from wastewater by conventional wastewater treatment processes.

A world first in biophysics

The introduction of VTA Nanocarbon® in the VTA Liquid Engineering series marks a significant milestone

in wastewater treatment.

Save energy & protect the climate

Thanks to its specific structure, VTA Nanocarbon® enables extensive and energy-efficient elimination

of pollutants in the existing treatment system at minimal dosage. VTA Nanocarbon® is added to the aeration tank of the wastewater treatment plant, ensuring optimal mixing and sufficient contact time.p>

VTA Nanocarbon®

VTA Nanocarbon® is extremely effective and cost-saving in wastewater

treatment, even at very low dosages, and can replace the 4th treatment stage.
