The table indicates continuously supplied thiocyanate feed concentrations, hydraulic retention times (HRT), and loading rates in molasses (M) or water-based (W) reactor systems (R1–R5). The arrows in the Table indicate the points from which the experimental conditions in the reactors were held at a SCN^– feed concentration of 250 mg/L (0.36 mM/h).
