Chemisch - In-situ Chemische Reductie

A recently proven technique is in situ chemical reduction (ISCR). Verhoeve Environment & Water frequently applies this in soils contaminated with chlorinated solvents (VOCL). It is based on the chemical reaction of zerovalent iron with chlorinated compounds, according to: 2Fe + R-Cl + 3H2O = 2Fe + R_H+ 3OH-+ H2 + Cl-. Verhoeve Environment & Water created a reactive and permeable lightweight material, based on combining zerovalent iron with lightweight clay granules. This product is patented by us under the name Granul-X ® and has already been applied successfully to a number of locations in Flanders. Advantages: better ground water flow, more durable and financially attractive in comparison to standard zerovalent iron. Zerovalent iron can be used in permeable reactive walls, for direct injection on Micro or Nano scale and can optionally be mixed with carbon source. Evidently, it is of the utmost importance that such mixing and injection is performed anaerobically.
