Treatment of Sulphate Rich Effluents with the Combined Electrolytic/Biological Process
Laboratory work on producing hydrogen by electrolysis as the energy source for sulphate reducing bacteria, aimed at cutting the running cost of treating sulphate rich mine water.
by JP Maree, JJ Smit & BJ Bladergroen | April 2003
Hydrogen for biological sulphate removal can be generated on site by electrolysis more cheaply than it can be bought. Stainless steel electrodes in acid mine drainage gave hydrogen at about a third of the bought in price while oxidising ferrous iron to ferric, which helps downstream treatment. Iron and zinc electrodes dissolved too quickly to be viable.

Ion exchange treatment of acid mine drainage from a closed KwaZulu-Natal colliery was piloted and shown to give effluent free processing, converting the salts into saleable products rather than sludge and brine. Reverse osmosis had previously produced water of discharge standard but left both. Combined flow from the two mine compartments averaged 4.6 megalitres a day.
