The study included testing the susceptibility of algae (Oscillatoria pseudogeminata) in removing phytonutrients consisting of ammonia, nitrite, nitrates, active phosphorus, and total phosphorous. As well as the ability of these algae to reduce the chemical requirement of oxygen from the domestic wastewater, in addition to its effectiveness in removing some heavy metals (iron, copper, lead, nickel). This algae was used in the form of the Unialgal culture obtained from the algae plant in the fish department. The results indicated that the efficiency of O. pseudogeminata was better than the other two types. Where the removal was complete (100%) for both ammonia and active phosphorus during the seventh day of treatment. 79% of total phosphorous was removed after ten days. The ability of the algae was lower in removing nitrites (70%) and nitrates (80%), and the algae was able to reduce the chemical requirement of oxygen to 80% during the treatment period. The heavy metals were removed 100% for iron, copper, lead and nickel on the ninth day.
