THE EFFICIENCY OF USING MORINGA OLEIFERA SEED AND ALUMINUM SULFATE IN WATER TREATMENT
Abstract
The aim of the present work was to investigate the efficiency of using Moringa oleifera seeds and aluminum sulphate in water treatment. Water was collected from Ajiwa dam, and the Alum was bought from local market in Batagarawa, Moringa seed pods were collected from Moringa tree. The seed pods are shade dried for a week, the pods are dissected and the seeds were removed from the pod. The seeds were deshelled and the kernel were obtained. Nutrient Agar was prepared according to manufacturer’s instruction to obtain Single Strength and Double Strength broth and autoclaved at 121°C for 15mins. Endo Agar was prepared according to manufacturer’s instruction and autoclaved at 121°C for 15mins. 2g of Moringa was added in to 200ml of water for 24hrs at room temperature. The mixture was filtered and 1ml of the filtered water was placed on a plate. Nutrient Agar was poured in to the 1ml filtered water and was placed in an incubator for 24 hours, Endo Agar was poured into the 1ml filtered water and was placed in an incubator for 24 hours, the growth was checked and the procedure was repeated in 4g,6g,8g and 10g. The same process was applied to Alum also. The present study compared the coagulation potential of Alum (a hydrated double Sulphate salt of Aluminium.) and Moringa oleifera. In the present study, it was observed that the turbidity values of Alum decreased with increasing concentration. The reverse was observed for M. oleifera as the turbidity increased with increasing dosage. From the above result, it can be concluded that both aluminum sulphate and Moringa oleifera seeds powder served as primary coagulants in water purification. They all gave clear water, but aluminum sulphate gave clearer water than Moringa oleifera seed. Aluminum sulphate remain a better coagulant in water purification or settlement than moringa oleifera seeds powder, because it gives more clear water and produced larger, heavier and stronger flocks (coagulated dirt).
