Abstract
This study was conducted to apply phytoremediation technology in removing pollutants from wastewater to reuse it for different purposes; this technology is considered one of the promising technologies, as it is environmentally friendly, cost-effective, and removing pollutants. The experiment was conducted in the Al-Tuwaitha location (Iraqi Atomic Energy Agency, IAEA). Six glass tubs of (30×30×30) cm dimension and 27 L capacity each were filled with sewage water that brought from Al-Rustomia sewage plant after primary treatment stage bowl, 100g of Azolla plant which brought from Al-Chibayish Marsh in the south of Iraq were placed in three tubs and the other three was without plants (control) after 28 days the plants were harvested. Many pollutants and nutrients were determined every week. The results showed that the percentage of (SO4, Cl, PO4, NO3, COD, BOD, Ec) removing was (56, 52, 55, 52, 46, 42.5, 23) % respectively at the first fourteen days, and at 2nd fourteen days was (83, 76, 84, 76, 79, 63, 49) % respectively.
