Over the past six years, we have studied the use of iron shavings, especially turnings or shavings of 38CrMoAl steel (Figure 1) for enhanced biological treatment of industrial process wastewater. The iron shavings contain iron (>95%), carbon (0.35−0.42%), silica (0.2−0.45%), chromium (1.35−1.65%), and a few other trace elements (e.g., Mo, S, P, Ni, each <0.03%).
