Using Of Method Ozonetion for Mineral Water treatment

Mineral water and drinking water are one of the vital and immediate needs for human beings. Depending age and weather, everybody needs about one to two liters. The origin of %80 of human diseases are unavailability of healthy water.%75 percent of people in developing countries are deprived of facilities for water. Actually, healthy water scarce and expensive. Pollutions descend quality of water by changing it physically, chemically and biologically.Some of the pollutions are decadence and can be decreased easily, like human, animal and agricultural drainages.Some of the pollutions are undecadence, like polop and Mercury, and plastices that we should reduce them in water. In this reseach two samples of mineral water found in northern Mahabad, west Azarbaigan, with hardness of 42, 36 mg/l(CaCo3) are investigated. Then, different amount of Ozone gas is injection in to mineral water and biological and chemical changes probed. The used Ozonator can produce 25 mg Ozone per hour.We used iodometry method in order to determine amount of ozone gas. In injection of 1.25 mg/l we have done complete removal of diatomaceae in sample (1) and up to 99 percent in sample (2). Both had complete removal of chlorophyceae in 1.1 mg/l complete remove of BOD5 sample 1 in 1.1 mg/l Ozone and sample 2 in 1 mg / lit ozone are produced. We had 65 percent reduction of COD for injection of 1.2 my Ozone for sample (1) and 68 percent for sample (2). Complete disinfection is done in both by 0.5 mg per liter.In this method agreeable water is achieved because no chemical is used and we don’t need to provide chemical substance. So, we can introduce Ozonetion the best method for water treatment
