Abstract
The invention provides a process for removing polyamine chelating agents from aqueous solutions comprising oxidising the chelating agents with oxygen in the presence of an equivalent amount of a transition metal such as iron, followed by biologically reducing the chelates in the presence of an electron donor, and optionally by membrane filtration. The biological reduction is carried out with denitrifying and/or sulphate-reducing bacteria.
