Application of two fungal strains Aspergillus niger and Candida albicans in wastewater quality improvement

The nutrients Phosphorous, Nitrogen and Carbon are essential for aquatic life. However, in excess they also cause serious problems. For this reason, wastewater treatment must meet nutrient effluent limits. A sample was taken near Dhahibah village from the Erbil channel north of Iraq. In experiment, pure cultures Aspergillus niger Candida albicans were used to treat wastewater. Samples measured physicochemical parameters like EC, pH, Phosphate, Nitrate, Nitrite, BOD5 using standard methods every third day during 21 days experiment. results revealed that had maximum efficiency removing BOD5, NH4, NO3, EC (87.27, 89.57, 83.52, 78.49%) respectively. On other hand, experimental period, decreasing PO4, NO2, (91.58% 88.89%), Statistically, there differences (P≤0.05) between control treated both fungal stains all
