Use of ionizing radiation technology (Co60)‎ for treating crude water

Abstract EN

Water is the essential element for forming societies, the emergence and prosperity of cities.

therefore, water treatment is one of the essential processes in daily life to obtain water safe for human health and reduce the damage from liquid waste resulting from human and industrial activities for possibility of its reuse.

one of the most water quality treatment techniques is the ionizing radiation.

current study showed that the exposing raw water of Shatt al-Arab river to gamma rays (caused by the radioactive isotope of cobalt Co60) in the intensity of the radiation (0.029, 0.087, and 0.70) Msv / y for different periods (1, 3, and 48 hrs.).

the result showed that treated samples for 48 hours have lower values of (turbidity, dissolved oxygen, biological oxygen demand, total suspended solids, and nitrite) as compared with control.

the total number of fecal coliform bacteria decreased sharply in the treated samples for 3 hours, while the values of active nitrates increased after treatment for one hour.

also, the pH and active phosphates values were increased compared to the control treatments.
