Upgrade of Al-Aziziah wastewater treatment (Wasit)‎ to meet nutrient removal requirements

الملخص EN

The aim of this paper is to verify of suggestions to upgrade the existing process of wastewater treatment to achieve nutrient removal (phosphorus and nitrogen) from the treated wastewater.

The results show that the adding a cyclic anaerobic, anoxic and aerobic condition helped to biological nutrient removal efficiencies.

The effluent phosphorus and nitrogen contaminants concentrations were below the maximum permissible concentration under various conditions of flow and temperature except considerable release of phosphorus during summer (July and August) because the sensitivity of phosphate accumulating organisms PAOs to the temperature effect.
