This research presents the effect of shelled and unshelled Moringa seed on fecal coliform in water treatment. Bacteriological analysis was conducted on a natural occurring water to examine the effect of the shelled and unshelled Moringa seed on fecal coliform reduction. The treatment variables, shelled and unshelled Moringa seeds were used under the same temperature and environmental conditions. Raw water samples were collected and subjected to post-treatment analysis. The treatment variable was used at a treatment level of 50ml and 75ml Moringa seed aqueous solution which was produced at 40g/l. The presence and reduction of fecal coliform was analyzed. The shelled Moringa seed aqueous solution produced an average of 76% fecal coliform reduction level as against the unshelled Moringa seed aqueous solution with 73.5% fecal coliform reduction level. The result showed that the lowest coliform level was 1811cfu/ml and 1899cfu/ml after treatment with the shelled and unshelled 50ml Moringa Oleifera seed sample respectively while at 75ml treatment level, the result also showed 1860cfu/ml and 1977cfu/ml respectively for the shelled and shelled Moringa seed sample. The analysis showed clearly that the unshelled Moringa will serve as a better fecal coliform reduction agent. Read full PDF
