| Summary: | Aluminum plates have been used for treating sewage by exposure to the direct solar radiation in the normal conditions of Mosul city using transparent plastic containers with capacity of 5 liters and four treatments (t1 sewage without dilution, t2 diluted sewage with conc. of 75%, t3 diluted sewage with conc. of 50% , t4 diluted sewage with conc. of 25%) ,the measurements have been concluded to: pH, EC25, BOD5, T H., some cations and anions, and indicators of bacteriological contamination etc. according to international standard methods . The studying reveals a significant improvement in the transparency and water quality, the removal percentages of organic load, TH, calcium , chloride and phosphate reached to ( 86 , 55.53 , 50 and 81) %, respectively, toward the end of the treatment, while the removal percentage of bacterial total number was up to 96% in the fourth day of the treatment, but reached to 100% for both fecal coliform and E. coli in the third day of treatment, as a result of the impact effect of water temperature and solar radiation, as well as the role of aluminum plate in utilizing as much as possible of the reflected rays to stimulate photochemical reactions |
