This study was conducted to determine the ability of water treatment system (Vortisand) to reduce some chemical and physical properties for tigris river raw water, It consisted of turbidity, electrical conductivity, pH, total hardness, calcium Hardness as well as temperature in order to determine the unit`s efficiency for reducing their concentration as compared to those in the water produced by some classical potable water projects (Dora and Wathba) in Baghdad. Samples were collected during the cold months (December 2016 and January 2017) and during the hot months (May and June 2017). The results showed that this system has the ability to reduce some properties such as turbidity, the values were 215NTU in raw water and decreased to NTU 2.8 during the cold months and NTU343.3 was reduced to NTU 125 during the hot months while it has no significant effect in reducing some properties such as total hardness of 503-513.3 mg/ L in produced water and calcium ranged from 131.3-160.5 mg/ L during the cold and hot months, respectively, and the properties in produced water fall within the permissible limits of potable water according to the Iraqi and international water quality standards.
