Sažetak
The coagulation/flocculation process was employed for the treatment of reactive dye wastewaters. FeCl3 6H2O was used as a coagulant. The process was found to be very effective with a more then 99.5 % color removal. Typical representatives of monochlorotriazine reactive dyes, with azo and anthraquinone chromofores, C.I.Reactive Red 45 (RR45) and C.I.Reactive Green 8 (RG8) were chosen as model dyes. In order to obtain the optimum pH range and coagulant concentration a series of jar tests was done. Further experiments were conducted using a square flocculation tank with turbine impeller applying rapid and slow mix operations. The optimization of initial rapid mixing which have an important role in the overall coagulation process efficiency was carried out. The optimum combination of velocity gradient and time of rapid mix was suggested for reactive dye wastewater treatment. Sedimentation curves for both model dyes were obtained as well.
