Abstract

The paper deals with possible synthesis and use of potassium ferrate(VI) (K2FeO4) for the treatment and disinfection of carwash wastewater. Potassium ferrate(VI) was synthesized by wet method and the quality of the product was studied by SEM/EDX. The purity of the product was 90%. The treatment process was optimized by CCD and RSM. The optimum conditions for COD were established at pH 5.8, 0.97 g/L dose of K2FeO4 and with reaction time 23 min. Simultaneously, COD was decreased by 79.8%. At the same conditions the total proteolytic bacteria decreased by 92.1%. The application of ferric chloride as coagulant was also evaluated. The study indicated that the use of potassium ferrate(VI) and anionic flocculant is the better option than the use of ferric chloride and the same flocculant. The application of potassium ferrate(VI) is a viable option for the treatment of carwash wastewater.
