NanoRem Pilot Site – Spolchemie I, Czech Republic: Nanoscale zero-valent iron remediation of chlorinated hydrocarbons

This bulletin describes a pilot study of in situ nanoscale zero-valent iron (nZVI) remediation. It was undertaken as part of the NanoRem Project.

Zero-Valent Iron Nanoparticles
Pilot Injection of Nanoscale Zero-Valent Iron - Kara Trutnov site (CZ)
Groundwater contamination at the KARA site is caused mainly by obsolete technological practices and irresponsible handling of chlorinated ethylene and chromium compounds during processing of fur in past. Injection of nZVI has been proposed to finalize the treatment of the site.

Combined abiotic and biotic in-situ reduction of hexavalentchromium in groundwater using nZVI and whey: A remedial pilot test
The paper describes a pilot remediation test combining two Cr(VI) geofixation methods – chemical reduction by nanoscale zero-valent iron (nZVI) and subsequent biotic reduction supported by whey. Combination of the methods exploited the advantages of both – a rapid decrease in Cr(VI) concentrations by nZVI, which prevented further spreading of the contamination and facilitated subsequent use of the cheaper biological method. Successive application of whey as an organic substrate to promote biotic reduction of Cr(VI) after application of nZVI resulted in a further and long-term decrease in the Cr(VI) contents in the groundwater.
Distribution and Storage
Product availability: 500kg of slurry is usually dispatched in one day. Please consider using NANOFER STAR dry powder and preparation of fresh slurry by our dispersing unit in case you require larger quantities.

NANOFER slurry products are distributed in plastic canisters (capacity 5, 10 or 20 kg), small samples are available in PET bottles (100g, 250g, 500g). Storage in glass is not recommended due to pressure build-up.

Shelf-life: NANOFER slurry products are an extremely reactive dispersions of iron nanoparticles that – if in contact with oxygen or water – intensively oxidize. NZVI, which is capable of efficient reduction of contaminants in water, transforms into iron oxides and hydroxides. For this reason it is necessary to process the material as soon as possible, we do not recommend to store NZVI aqueous dispersions for a long time. If you need to do so, please store it in cold premises (5°C) in order to reduce corrosion rate. For more information, please read the article about nZVI slurry ageing in the download section.
