| Abstract | ||
| Bacillus apiarus, Bacillus filicolonicus and Bacillus laterosporus were used to degrade organic pollutants from final discharge of Al Dura wastewater treatment plant in Baghdad and reduce their concentrations by measuring Chemical Oxygen Demand (COD), Total Organic Carbon (TOC), Total Nitrogen (TN) and Total Phosphorus (TP) in laboratories conditions of 25o c, pH 5.8-6.8 in batch culture system and 18hr period treatment, the bacteria Bacillus apiarus, Bacillus filicolonicus and Bacillus laterosporus showed ability to reduce COD concentration by(82, 88.5, 94)% and TOC concentration by (73, 82 ,84)% and TN concentration reduced by (86, 91, 81)% in 18 hr period treatment with highly significant differences P<0.01 for all bacterial treatments, the bacteria in the current study showed high ability to reduce TP concentration by 100% with highly significant differences P<0.01 for all bacterial treatments in 18hr period treatment. | ||
