Description

To confirm the performance of a treated swine wastewater decolorization system, the combination of an Ozonation Process and a sand filter was investigated.<br>This study made use of an Ozonizer with a titanium dioxideelectrode and a honeycomb structure, which produced 3g-Ozone per hour.<br>In Experiment 1, the decolorization conditions of the low concentration composition against chromaticity in thetreated swine wastewater were examined. Likewise, in Experiment 2, decolorization conditions of the high concentration composition were examined. In both experiments, the volume of treated swine wastewater in a reactor tank was 300 liters.<br>The results showed that the Ozone production was not affected by temperature or moisture. In Experiment 1, a chromaticity of less than 50 degrees was obtained at about 4 hours, whereas in Experiment 2, low decolorization and high Ozone consumption was found.<br>These findings indicated that a low concentration of COD and NOX-N in the treated swine wastewater was obtained by use of this low cost Ozonation Process.
