sachverstaendigen-gutachten-vta-nanocarbon

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.

VTA Nanocarbon® replaces the 4th cleaning stage

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.

Wastewater Treatment Plant Manager 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 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.

Increasing the treatment performance of wastewater treatment plants

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.

Sedimentation

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.

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 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.

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 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®

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>
