Disinfection of stabilization pond effluent by peracetic acid and sodium hypochlorite
Aims: In this study, the efficiency of peracetic acid (PAA), sodium hypochlorite (NaOCl) and combination of both disinfectants for disinfection of stabilization pond effluent was assessed. Materials and Methods: The samples was collected during four months. All samples were analyzed as triplicate ac...
