A slow chemical reaction rate of dissolved ozone and pollutants present in raw water have been experimentally determined. The modified Hatta number was defined and calculated as a criterion which determines whether and to which extent the reactions of ozone and pollutants influence the rate of the pure physical ozone absorption. %K ozone %K absorption %K chemical reactions %K raw water %K continuous stirred tank reactor (CSTR) %U http://www.ache.org.yu/CICEQ/2008/No1/06_2985_2008.pdf
