Abstract:
Water can be considered as the most important natural resource that can be utilized by man to develop his prosperity as well as his essential needs. Raw water contains different types of impurities that have harmful effects on human health. Water is subjected to some forms of treatment before its use. The main goal of water treatment is to produce potable or acceptable water to use which is biologically and chemically safe for human uses and meet certain water quality standard. The principal target of this study was to investigate Moringa oleifera capability of water treatment against the traditional methods of purification using chlorine and Aluminum sulphate (Alum) in turbidity, algae and bacteria removal. Moringa oleifera was proved to be efficient when used in specific dose (50 mg/l) with settling time 120 min make 90% removal of turbidity 91.7, 84.8, 87, 91.4% for Diatoms, green algae, blue green algae and total algal count respectively. While the removal of bacterial groups were 88.4, 90, 94.3, 100% for total bacterial count, total coliform, fecal coliform and Fecal streptococcus. Then studied doses of Moringa oleifera with alum alone, different doses of Moringa oleifera with chlorine, then different doses of Moringa oleifera with the traditional method (alum and chlorine).the study showed that the best result in algae and bacteria removal was 50% of Moringa oleifera and 50% of (alum with chlorine). It also helped to reduce the cost of chlorination and Alum usage and maintain human health. |
