| Abstract | ||
| This study is the first in Iraq, in which the use of the Al-Ruwag tree seeds that were planted from seeds imported from Sudan and the age of the tree three years, and this is the second season of harvested bods. Al-Ruwag tree is very useful and all parts of the tree have potent medicinal value and seed has coagulant activity to remove the turbidity from water as a natural coagulant instead of chemical coagulant. In the present study preparation of dried seed powder of Al-Ruwag tree in many concentrations and that was treated with raw water. After treatment with raw water by Jar test, samples were analyzed for all the parameters such as pH, turbidity, TSS, and bacterial examination. The results of the present study showed that Al-Ruwag seed has more coagulant activity specific at concentration 10 and 15 percentage, in this concentration the turbidity values and total suspended solid were zero. The results of the present study demonstrated the of Al-Ruwag seeds extract was efficient against bacteria found in raw water. The concentration (1%, 2%, 3% and 5%) of Al-Ruwag seeds extract reduced the number of bacteria in raw water to about (93.75%, 95.5%, 99.37% and 99.68%) respectively. Whereas the concentration (10% and 15%) of Al-Ruwag seeds extract reduced the number of bacteria to 100% .We conclude from the current study that the Al-Ruwag seed is environmentally friendly, non-toxic and a natural coagulant, which is effective against the causes of water-borne diseases. | ||
