| Abstract | ||
| The trendof algal immobilization and impact them inphycoremediation of pollutants in wastewater is a new technique that did not enter into Iraq even though it is growing in other countries. In the current study We use of a number of algae in both free and immobilized status inmunicipal wastewater treatment.The results showed that immobilized algae Stigeonema spand Cladophoraglomerata have been reduced pH, which began baseline and finished tied 7.8 and 7.4, as well as increased concentrations of dissolved oxygen in the end of the experiment in all treatments free and immobilized comparing with the control group and increased the amount of dissolved oxygen by 67.06%.On the other hand, treatment with algae contributed to reduce of total suspended solids TSS by 61.81% at treatment the immobilized C.glomerata least it was when algaStigeonemasp in the immobilized condition. The studied algae reduced about 85.5-96.7% of nitrite byC.glomerata and the Stigeonemasp respectively and reduced about 95.2-99.93% of nitrate by C.glomerata and S.dimorphus respectively ,At last removal of phosphate was at its peak when treatment Stigeonemasp in its free state and reached to 99.93% and immobilizedS.dimorphuswhich remove about98.35%of phosphate | ||
