Abstract
Access to drinking water is a universal right of human beings that has not been achieved globally, so it is necessary to continue working to achieve it. Humans and other living things depend on water for life and health. Forests have long been seen as an important source of clean drinking water. The high cost of treated water makes most rural communities resort to readily available sources that are normally of low quality, exposing them to water-brown diseases. In this light, this research was carried out to confirm the effectiveness of powder extracted from mature-dried seeds of Moringa oleifera, Parkinsonia aculeate, and Jatropha curcas for clarification of water. In the present study, various doses of Moringa oleifera, Parkinsonia aculeate and, Jatropha curcas seeds coagulant were added as 5 ,10 and 20 grams per liter of decanted water. Treated water was kept stable for 0 (control), 12, 24 and 48 hours. With increasing coagulant doses. The measured parameters such as pH, turbidity, TDS, TSS, watercolor, colony-forming unit (CFU), temperature, and electrical conductivity were decreased. Also, the lowest turbidity was achieved by settling time T4, since it displayed 4.29 (NTU), 9.42 (NTU) and 8.72 (NTU) for M. oleifera, P. aculeate and J. curcas seed powder, respectively. Furthermore, the total bacterial count at settling time T1(control) gave the highest CFU 232.48×103 cfu∕ ml, 301×103 cfu∕ ml and 297.71×103 cfu∕ ml for M. oleifera, P. aculeate and J. curcas seed, respectively. On the other hand, the total coliform detected the highest total bacterial count in water samples treated with Parkinsonia aculeate tree as compared with the two other trees; it was 391.3×102 at the second concentration. Therefore, the main objective of this experiment was to evaluate the efficiency of natural absorbents from Moronga oleifera, Parkinsonia aculeante, and Jatropha curcas in treating drinking water.
