Efficiency Of Moringa Oleifera Seeds As A Natural Coagulant For Removal Of High Turbidity And Bacteria Compared With Aluminum Chlorohydrate In A Rural Community, Blue Nile, Sudan

Abstract

The Moringa Oleifera seeds known a (the purifying tree) in Arabic known as (shagarat al rauwaq), were investigated to remove turbidity and reduce total coliform. The water was collected from the Blue Nile during a rainy season at high turbidity 4000NTU.The results show that Moringa has ability to reduce turbidity up to 4.95 NTU below the World Health Organization’s(WHO) and The Sudanese Standards and Metrology Organization (SSMO) guideline value of 5 NTU for drinking water. It reduced the total coliform by 85% after 24 hours. The studies have also shown that pH, alkalinity, electric conductivity and total dissolved solid conformity with WHO and SSMO standards for drinking water. There was a decrease in the concentration of nitrate and phosphate, with increase in phosphate, but below within permission. Moringa shows remarkable ability to remove high turbidity and reduce total coliform with low cost and simple method for rural people living in the Blue Nile area.
