Indicator material comprising a polymeric gel carrier and polymeric indicator

Indicator material comprising a polymeric gel carrier and polymeric indicator

The invention relates to a polymeric indicator fixed in a polymeric gel carrier, wherein the polymeric gel carrier comprises a hydrophilic polymer, wherein the polymeric indicator and the hydrophilic polymer are present together in the form of a combined cross-linked hydrogel network fixed by chemical bonds.

Biofilm carrier

Biofilm carrier

This invention relates to a biofilm carrier made of structured yarns (1) comprising filaments (2), where each individual filament (2) constituting the central yarn (1) forms a continuous fibre running over the entire length of the yarn (1) and filaments (2) are fixed to each other by anchor points (3) along the length of the yarn (1), and structured yarns (1) are fixed at fixing points (5) of a mesh structure (6), and each structured yarn (1) forms a loop (4) between two adjacent fixing points (5), the arc length (T) of which is greater than the distance (t) of the two fixing points (5).

Nanoiron suspension, process for the preparation thereof its use and device for the preparation of nanoiron suspension

Az elemi vas nanorészecskék (nZVI) hatékonyan ártalmatlanítják a különböző klórozott szerves vegyületeket, megkötik a talajvízben található nehézfémeket. A találmány tárgya egy nanométeres tartományban levő méretű, szilárd vas részecskéket tartalmazó, vizes vas-szuszpenzió, továbbá a találmány szerinti vas-szuszpenzió alkalmazása szennyezőktől való mentesítésre, előnyösen talaj, víz, szennyvíz vagy gázelegyek tisztítására. A találmány tárgya továbbá berendezés a találmány szerinti vas-szuszpenzió előállítására.

Installation for preparation of nano-iron suspension

Installation for preparation of nano-iron suspension

The elemental iron nanoparticles (nZVI) efficiently decontaminate the different chlorinated organic compounds, absorb the heavy metals found in the underground water. The technical problem to be solved by the invention is the implementation of a device which ensures the production of a stable, aggregation-free and oxide-free nano-iron, even for the remediation of industrial-scale contamination, and for reducing the storage and transport time of said nano-iron.
