- •
In-situ whey application after nZVI supported microbes to reduce efficiently Cr(VI).
- •
Reduction was mediated mainly by iron and sulphate reducing bacteria.
- •
Bacteria recovered previously spent nZVI into Fe(II).
- •
Recycled nZVI and natural iron in Fe(II) form enabled further Cr(VI) reduction.
- •
Efficient Cr(VI) removal was observed for 10 months.
