ABSTRACT
The aim of this research was to evaluate copper catalyzed Fenton reaction for removal of Salmonella spp from fish pond water. Standard bacteriological methods were used to enumerate the total bacterial count of the copper catalyzed reaction and non-catalyzed reaction using pour plate methods after serial dilution. The bacterial isolates were characterized and identified using morphological and biochemical methods and sugar fermentation test. The percentage distribution and frequency of the isolates were evaluated using statistical method. The results showed that the enumeration of microbial population (bacteria) in copper catalyzed Fenton, Iron and non-treated wastewater sample were 3.33 X 101 ± 0, 18.00 X101±6.00 and 34.00 X 101 ±19.9 respectively. There was a significant difference (p<0.05) between the bacterial count for the copper Fenton treatment and the untreated wastewater. Following the cultural, morphological and biochemical characteristics of bacteria from water samples, the result revealed that Escherichia coli, Bacillus sp, Salmonella sp and Staphylococcus were present. Among the listed isolated isolates, only Bacillus spp was obtained from the copper Fenton reaction. The distribution of isolates across the treatment showed that copper had a total of 25%, iron had a total of 75% while the wastewater without fenton reaction had 100% of the bacteria in this study. Hence copper catalyzed fenton reaction was able to remove salmonella from the wastewater as salmonella wasn’t found in copper fenton treated water.
