Evaluation of Sodium Ferrate Efficiency in Processes of Meat Industry Wastewater Disinfection

The use of sodium ferrate as a disinfectant for industrial wastewater from such groups of pathogenic microorganisms as generalized coliform bacteria (GCB), bacteria of the genus Salmonella, Enterococcaceae and Staphylococcaceae is considered. Several types of wastewater were studied to investigate in more depth the possibility of using sodium ferrate for disinfection. It is shown that the use of sodium ferrate with the addition of 2, 3.5 and 5 vol. % of the current volume of the investigated wastewater samples has a high inactivation of the investigated pathogenic microflora. The most effective concentration for almost complete disinfection of real wastewater from the meat industry for all four microbiological indicators was identified: 5 vol. %.
