The four oxidants under consideration were ozone, chlorine dioxide, potassium permanganate, and chlorine, Experimentation was directed towards the impact of these oxidants upon turbidity, TOC, and color removal, as well as reduced manganese oxidation. Studies were conducted with an experimental water with enhanced TOC levels. Experimentation was accomplished by a series of jar tests in which solution pH, coagulant dose, and oxidant dose were varied. Results show that, in general, oxidant application had either no impact or a negative impact upon TOC, turbidity, and color removal. Further deterioration of finished water quality was observed with increasing oxidant dose. Reduced manganese was oxidized by both potassium permanganate and chlorine dioxide. Ozone effectively oxidized reduced manganese in waters of low TOC, while chlorine was an ineffectual oxidant. Additionally, particle counts were conducted. Results show that the application of an oxidant increased the number of smaller particles present alter settling However, this immense of particles did not significantly alter settled turbidity levels.","abstract_html":"The effects of four oxidants upon water treatment process parameters were investigated.
