Summary
This work reports a laboratory-scale study of the bacteriological treatment of sulfuric water residues produced during steel cleaning. A strain of Thiobacillus ferrooxidans was successfully subcultured in order to adapt it to differents pHs and dilutions of initial WPL. Once adapted, the bacteria were able to oxidize all ferrous ions in the diluted sulfuric water residues, producing iron and ammonium sulfates. By evaporation/crystallization and later calcination at temperatures between 800 – 1000 °C, hematite was obtained. The process produced 50 kg of Fe2O3 per m3 of waste pickling liquor with 99.8% weight iron recovery.
