Purification of the Diyala River Water Using Seeds Extract of Gusen Al-Ban Tree (Moringa oleifera Lamarck) Cultivated In Dura Area, Baghdad

Abstract

In this study, water samples were taken from three sites along DiyalaRiver. The third site of old Diyala Barrage was more polluted than the first sitesof Baʼqubah and the second site in Khan Bani Saad. For this reason, the watertaken from this site was treated with the seeds extract of Gusen Al-Ban Tree(Moringa oleifera Lamarck) and study the changes in water quality before andafter treatment. The preparation of dried seed powder of Gusen Al-Ban Tree ofthe six concentrations were activated with 100ml of distilled water and that wastreated with raw water in 20% of the dilution. After treatment with raw water byJar test, samples were analyzed for all the parameters such as pH, turbidity,TSS, and bacterial examination. The results of the present study showed thatGusen Al-Ban seed has more coagulant activity specific at concentration 10 and15 percentage, in this concentration the turbidity values and total suspendedsolid were zero. The results of the present study demonstrated that Gusen AlBanseeds extract was efficient against bacteria found in raw water. Theconcentration (1%, 2%, 3% and 5%) of Gusen Al-Ban seeds extract reduced thenumber of bacteria in raw water to about (93.75%, 95.5%, 99.37% and99.68%) respectively. Whereas the concentration (10% and 15%) of Gusen AlBanseeds, extract reduced the number of bacteria to 100%. It was concludedfrom the current study that the Gusen Al-Ban seed is environmentally friendly,non-toxic and a natural coagulant, which is effective against the causes ofwater-borne diseases.
