Abstract
Laboratory experiments were performed to study nutrient uptake by the
unicellular green microalgae (Chlorella vulgaris ) grown in batch system uses Al-
Asady Factory for Seeds and Animal Feed (Mahmodia/Iraq) industrial wastewater
as culture media .The initial concentration of C.vulgaris was 1*10 6 cells/ml with
48 hrs of incubation in wastewater at different temperatures ranges (20-35)°C
where changes in COD, BOD, total nitrogen and total phosphorus concentration in
the effluent were calculated.
The results show that the removal efficiencies of COD ,BOD ,nitrogen and
phosphorus are 88%, 89%,92% and 89% respectively. The optimum temperature
at which highest removal efficiencies were obtained was 30°C.
