Abstract

Water filtration is one of the oldest water treatmentprocedure used in eliminating pathogenic bacteria during water treatment in industries. This study aimed to assess the microbial load of water filtration units used in industries. Swab sticks were used for filter bed screening and samples were also obtained for raw and filtered water. Standard procedures were employed to perform microbial analysis of the samples.The raw water and sample swab microbial count ranges were 48 to 208 cfu/ml and 178 to 298 cfu/ml, respectively. Bacteria species isolated in this study were Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aureus, Enterobacter sp. Escherichia coliand Chomobacterium violaceum. No bacteria growth was observed in the filtered water samples. Water filtration units should be continuously assessed to affirm the quality of water used for production.
