Abstract

Water treatment plants play an important role in the purification and distribution of safe drinking water to the public. The present study focused on the performance assessment of the Al-Rasheed water treatment plant [ARWTP]. The main objectives of the assessment were to determine the efficiency of various plant units as well as the quality of inlet water from the Tigris River. Results obtained from the collected data indicated the presence of high concentrations of soluble nitrate and phosphate ions in the filtered water. The removal efficiency of alkalinity, EC, total hardness, SO₄, Cl, NO₃ and PO₄ were found to be (+11.05%), (-0.67%), (-29.33%), (-2.64%), (-6.25%), (-32.13%), and (0%) respectively. The removal efficiency was negative for some parameters which means that the concentration before treatment was less than the concentration after treatment. Water treatment facilities in Al-Rasheed water treatment plant need modernization and rehabilitation. Using pre-chlorination as an effective method for the controlling algal growth in the conventional water treatment plants is highly recommended.
