Nanotechnology is a relatively young field of research, which will keep the scientific community busy for a long time before it is fully recorded and documented in all its facets. Skeptics fear hazards in the use of nanoparticles, especially if they are integrated in foods or if they exist in loose form (as nanodust).
But scientists agree that nanoparticles are harmless to man and the environment if they are bound to a carrier agent. Even the nanoparticles integrated in the VTA Nanofloc are incorporated permanently onto a matrix of special organic charge carriers in order to accelerate or intensify its effect in sewage treatment systems.
Like all VTA product developments, even VTA Nanofloc was subjected to extensive technical trials before deploying it for practical use in order to rule out any negative effects.
An independent research and environment laboratory carried out multiple series of tests with the product. The result: VTA Nanofloc has no negative influence on the decomposing efficiency of microorganisms.
Nanotechnology deals with research and transformation of substances and systems, the individual atom size of which is not more than 100 nanometers.
A nanometer (nm) is one millionth of a millimeter. In a piece of metal, a nanometer is almost the length of four adjacent atoms. A skin cell is of the size of about 10,000 nm, a virus 100 nm, a nanotube 1 - 50 nm.
Nanoparticles are groups of a few to some thousand atoms or molecules. They have special chemical and physical properties, which clearly differ from those of solids or bigger particles. More importantly, they react more vigorously with other substances and can thus lend special properties to these substances.
VTA’s Nanofloc, a high-tech product based on the latest nanotechnology, opens up new dimensions in wastewater technology. With quick-acting effect and unequalled penetrating power, Nanofloc is miles ahead of all existing precipitants on the market. Integrated metal oxide nanoparticles are bound to special organic charge carriers and trigger powerful chemical reactions in the sewage plant as required. This, for example, enables the properties of the activated sludge to become immediately apparent and effectively improved.
Nanofloc not only works extremely fast but even at exceptionally low dosages and is therefore particularly cost efficient.
The practical applications of nanoparticles appear to be almost limitless – be it in medicine, optics, computer technology, industry or the food industry.
Today nanotechnology is being used in innumerable products. Nanoparticles in sunscreen block out harmful UV light; they make automotive paint scratch-resistant and allow dirt to simply roll off textiles.
Research in nanotubes is inspiring great hopes. Nanotubes are made of pure carbon and have a diameter of merely 1 to 50 nm. Depending on the structure, they can for instance conduct electrical energy or heat especially well and have 20 times the tensile strength of steel while still being ductile. In the future, they can play an important role as building blocks for nano-transistors, catalysts and biochip systems.
Concrete is known the oldest nano raw material, though it was only realized long after its first use that its strength is due to its crystalline structure, the size of which is only a few nanometers.
• causes extremely stable flocculation in record time
• visibly improves sludge formation properties immediately with a long-lasting effect
• ensures stable operation of the plant due to a low sludge index and high sedimentation rate
• controls floating sludge effectively
• prevents sludge drifting in the event of hydraulic overload
• reliably binds very fine floc and suspended matter in the post-clarification unit
• distinctly improves the result of sludge densification and dewatering
