The work
On an industrial site in the Basque Country, over man-made fill of carbonated ash, we injected FerroBlack®‑Fe by REDOX TECH to treat heavy metals through reductive precipitation (ISCR).
We treated the interval between 5.5 and 1.5 metres below ground with 42 injection points, 254 linear metres drilled and about 370 litres per point. The reagent was prepared in tanks with heating blankets and stainless-steel industrial mixers.
