“On this basis, the process is to be classified as a suitable alternative to GAC, PAC and ozone.”
KARL fulfills the legal requirement for micropollutant removal
PFAS-20 removal instead of 12.7% with ozone + GAC

Measured values from the Brannenburg and Imst wastewater treatment plants. Site-specific values must be verified on a case-by-case basis. Expert report by Michael Kocher, certified according to DIN EN ISO/IEC 17024 — Institute for Sewage Sludge Analysis, Detmold
Thanks to the special and innovative design of VTA Nanocarbon® with the largest possible active surface area, the most extensive 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 dosing quantities.
VTA Nanocarbon® can remove up to 99% of microplastic particles, especially in the lower micrometer range.
By using VTA Nanocarbon®, additional, not naturally degradable pollutant parameters such as AOX up to 93% can be bound from the wastewater.
The Liquid Engineering process using VTA Nanocarbon® guarantees high removal rates of trace substances
without expensive investments in conversion and expansion work, as well as the energy-intensive operation of a 4th treatment stage.VTA Nanocarbon® marks a significant advance in wastewater treatment as the latest development in
the VTA Liquid Engineering series.The compact floc structure is diffusion-permeable, so the introduced oxygen can be used optimally. This enables a reduction in aeration energy in the activated sludge stage by up to 30% and therefore makes an important contribution to energy and climate neutrality in the wastewater sector.
The measured values represent an average purification performance for various anthropogenic trace substances at different types of wastewater treatment plants over a measurement period of one year.

fewer microplastic particles
relevant trace substances are removed
less ventilation energy
Pollutant parameters such as AOX are bound from the wastewater
The average elimination rate required by the EU Urban Waste Water Treatment Directive is 80%. VTA
Nanocarbon®’s average trace substance elimination rate is 93%!
By maximizing the settling velocity of the solids, high 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.
Several test series 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.
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 contaminated. Microplastics also pose an ever-increasing threat to people and the environment, with particularly tiny, health-relevant plastic particles being insufficiently removed from wastewater by conventional wastewater treatment processes.
The introduction of VTA Nanocarbon® in the VTA Liquid Engineering series marks a significant milestone in wastewater treatment.
Thanks to its specific structure, VTA Nanocarbon® enables extensive and energy-efficient elimination of pollutants in the existing treatment system at a minimal dosage. VTA Nanocarbon® is added to the aeration tank of the wastewater treatment plant, ensuring optimal mixing and sufficient contact time.
VTA Nanocarbon® is enormously effective and cost-saving in wastewater
treatment, even at the smallest dosing quantities, and can replace the 4th treatment stage.p>Do you need more information?
