Mineral water and drinking water are one of thevital and immediate needs for human beings.Depending age and weather, everybody needsabout one to two liters. The origin of 80% ofhuman diseases is unavailability of healthywater,75%percentofpeople in developingcountriesare deprived of facilities for water.Actually, healthywater scarce and expensive. Pollutions descend thequality of water by changing it physically,chemically and biologically .Some of the pollutionsare decadence and can be decreased easily, likehuman, animal and agricultural drainages.Someof the pollutions are undecadence , like polop andMercury, and plastices. That we should reducethem in water,In this reseach two samples of mineral waterfound in northern Mahabad, west Azarbaigan, withhardness of 36 , 42 mg/l(CaCo3) are investigated.Then, different amount of Ozone gas is injectionin to mineral water and biological and chemicalchanges probed.The used Ozonator can produce 25 mg Ozoneper hourTo determine the amount of Ozone gaswe used iodometry method. In injection of 1.25mg/1 we going complete removal of diatomaceaein sample (1) and up to 99 percent in sample (2).Both had complete removal of chlorophyceae in1.1 mg/1 complete remove of BOD5 sample 1 in1.1 mg/1 Ozone and in sample in are my Ozone.We had 65 percent reduction of COD for injectionof 1.2 my Ozone for sample (1) and 68 percent forsample (2).Complete disinfection is done in both by 0.5 mgper liter.In this method agreeable water is achievedbecause no chemical is used and we don’t need toprovide chemicals. So, we can introduce Ozonetionthe best method forfiltertion water.Key words: Ozonetion, filtertion,
