Biological iron(II) oxidation as pre-treatment to limestone neutralisation of acid water

Author: Maree, JP ; Dingemans, D ; Van Tonder, GJ ; Mtimkulu, S Date: 1998 Iron (II) should be oxidised to iron (III) before the neutralisation of acid water with limestone, otherwise the oxidation will occur downstream of the neutralisation plant with the formation of acid (reactions 1 and 2). This study aimed at ... Read more
Integrated iron(II) oxidation and limestone neutralisation of acid mine water

Author: Maree, JP ; Strydom, WF ; De Beer, Morris Date: 1999 Volumetric iron (II) oxidation rates exceeding 100 g/(l.d) were achieved by dosing powdered limestone to a bio-reactor treating artificial acid mine water. Neutralisation and partial sulphate removal were achieved as well. The rate is highly ... Read more
