Alteration of Iron Level in Drinking Water by Aeration in Gonbad Kavoos (North East of Iran)

Problem statement: In this study, removal of iron was surveyed in well water in Gonbad Kavoos City. Approach: Samples were taken before and after aeration. Concentration of iron in each sample was measured by spectrophotometer. Results: The results showed that the iron concentration was decreased after aeration (0.55, 0.44, 0.44, 0.46, 0.40 and 0.41 mg L^-1) when compared with before aeration of water (0.64, 0.68, 0.65, 0.62, 0.65 and 0.67 mg L^-1), respectively. Conclusion: It was concluded that using aeration technology can reduce iron concentration conform to internationally approved guidelines for iron.
