| In this reseach, two samples of mineral water found in Northern Mahabad, west Azarbaigan, with hardnesses of 36, 42 mg/l (CaCO3) are investigated (.Kanisepi South Region, and Minerals of the Tutankhach Village Northern Region). Then, different amount of Ozone gas is injected into mineral water and biological and chemical changes are observed. The used Ozonator can produce 25 mg Ozone per hour. To determine the amount of Ozone gas. We used iodometry method. By injection of 1.25 mg/l we achieved complete removal of diatomaceae in sample 1 and up to 99 percent in sample 2. Both complete removal of chlorophyceae in 1.1 mg/l complete removal of BOD 5 sample 1 in 1.1 mg/l Ozone and in sample (2 in 1 mg/l Ozone complete removal).We had 65 percent reduction of COD by injection of 1.2 mg Ozone for sample 1 and 68 percent for sample 2.Complete disinfection is done in both samples by injection 0.5 mg per liter. In this method clean water is chieved because no chemical is used and we don’t need to provide chemicals. So, Ozonation can be introducd as the best method for filtration of water. DO: Dissolved Oxygen BOD: Biological Oxygen Demand COD: Chemical Oxygen Demand. | ||
